Boosting Sound Quality: Optimizing the Volume Settings on Your Computer

Have you ever experienced a moment when you wanted to blast your favorite song or watch a video with crystal-clear audio, only to find that the volume on your computer was disappointingly low? Fear not. In this article, we will explore different ways to turn up the volume on your computer and enhance the sound quality for an immersive audio experience. So let’s dive in and learn how to optimize the volume settings on your computer.

Adjusting System Volume

One of the most basic steps in optimizing your computer’s volume settings is adjusting the system volume. To do this, locate the speaker icon in your taskbar (usually found at the bottom right corner of your screen) and click on it. A slider will appear, allowing you to increase or decrease the system volume level. Dragging it towards the right will amplify the sound output, while dragging it towards the left will lower it.

It’s important to note that some computers have additional volume controls within their operating systems. For example, Windows users can access advanced audio settings by right-clicking on the speaker icon and selecting “Open Sound Settings.” Mac users can find similar options by clicking on “System Preferences” and then selecting “Sound.” Exploring these additional settings can provide even more control over your computer’s sound output.

Using Media Player Controls

Another way to boost sound quality on your computer is by utilizing media player controls. Whether you’re listening to music or watching a video, most media players come with built-in features that allow you to adjust volume levels independently.

In popular media players like VLC or Windows Media Player, look for a speaker icon or a volume control bar within their user interfaces. By increasing these controls’ levels, you can amplify sound directly from within the media player itself. This method is particularly useful when you want to fine-tune audio levels for specific media files without affecting your system’s overall volume settings.

External Speakers or Headphones

Sometimes, the built-in speakers on your computer may not provide the desired sound quality. In such cases, connecting external speakers or headphones can significantly enhance your audio experience. External speakers come in various sizes and price ranges, allowing you to choose the one that suits your needs and budget.

When connecting external speakers or headphones to your computer, make sure they are properly plugged into the audio output jack. Once connected, adjust their volume controls independently from your computer’s system volume. This gives you an additional layer of control over sound amplification and allows for an optimal listening experience.

Enhancing Sound with Software

If you’re looking to take sound optimization a step further, consider using software solutions designed to enhance audio quality on your computer. There are numerous applications available that offer advanced features such as equalizers, sound boosters, and virtual surround sound technology.

Equalizer apps allow you to fine-tune different frequency ranges, giving you precise control over bass, treble, and other audio components. Sound boosters can amplify sound beyond the maximum level offered by your operating system. Virtual surround sound technology creates a more immersive listening experience by simulating multi-channel audio through stereo speakers or headphones.

With these tips in mind, you can now optimize the volume settings on your computer like a pro. Whether it’s adjusting system volume levels, utilizing media player controls, connecting external speakers or headphones, or enhancing sound with software solutions – there are plenty of options available to suit every need and preference. So go ahead and turn up the volume on your computer to enjoy an incredible audio experience like never before.

How to set boot disk flag with diskpart

My Windows Server 2008 R2 won't start and stops with Stop 7B, so I start the recovery console and use diskpart to check the disk. There are to partitions one of Type 17 and one of type 07, the detail disk command show me that the disk is not a boot disk. How can I set this boot flag with diskpart? Or is this flag only set true if the MBR works fine. I try following commands:

the last command show me the number of OS is 0, so how can I set this flag to true?

• you should detail how you fixed it, so that others can benefit. And if you can't remember then you should have detailed how you fixed it so that others could benefit –  barlop Dec 20, 2015 at 1:37
• 2 As I mentioned in the Comments of your answer it was a issue with the driver signature. After deactivate the signature verification while startup I can start the system reinstall the driver and everything works well. So the solution was to recreate the MBR and start without driver verification. –  kockiren Dec 20, 2015 at 5:26
• 1 To clarify: Bugcheck 0x7b (INACCESSIBLE_BOOT_DEVICE) means that Windows did indeed begin booting, but was unable to find a driver for accessing its partition after switching to direct storage access. –  Daniel B Dec 30, 2015 at 11:55
• Note: As I understand it, "Boot disk" in diskpart only means that this is the disk from which the Windows has booted. Not that the disk is bootable from the BIOS. In addition, use "list volumes" to see which is the "System" volume, which contains the Windows OS currently running. (These might be in different disks.) –  Shalom Craimer Oct 19, 2022 at 6:33

The diskpart in recovery console doesn't allow you to make a partition active(bootable).

Use Gparted Live.

http://en.wikipedia.org/wiki/Diskpart "On the Recovery Console, which is included in all Windows 2000, Windows XP and Windows Server 2003, there is a diskpart command which is significantly different from the one included in the actual operating system. It only provides functionality for adding and deleting partitions, but not for setting an active partition. The utility is also provided in the Windows Recovery Environment, the successor of the original Recovery Console"

• I boot from a live-Linux and start gparted. The Bootflag is set but the detail disk show me "boot disk" no –  kockiren May 18, 2013 at 11:14
• 1 @kockiren there are some more commands you can try social.technet.microsoft.com/Forums/en-US/winserversetup/thread/… like sfc (with some parameters like sfc /SCANNOW /OFFBOOTDIR=d:\ /OFFWINDIR=d:\windows where d is your windows drive) and startrep.exe and if both those fail then you might have to reinstall windows. As windows server 2008 apparently has no repair installation w7 has no repair installation either! xp does. –  barlop May 18, 2013 at 11:47
• 1 also if you just made it active/bootable when it those commands can't see windows, then you're not likely to be able to even start getting into windows. if you can reach a stage where those commands can see windows, particularly the rebuildbcd command which found 0 Oss, if running those other commands leads it to find the Os then great, if not, then maybe that's a basic problem that leads diskpart to not see that it's bootable when gparted set it to bootable. –  barlop May 18, 2013 at 11:51
• I run sfc and startrep but it dosent help. No bootrec /rebuild find a Installation but the System won't start correctly. It stops with 7B and now Dumpfile was create :-( –  kockiren May 18, 2013 at 12:00
• 1 I didnt need a fresh install, Windows won't start with Drivererrors, after I fix it windows start correctly and then the Boot Disk flag is set. –  kockiren May 18, 2013 at 18:54

I have successfully restored an VHD GPT-disk from a Windows 8.1 PC combining information from this and other threads on another windows 8.1 Hyper-V-Server.

• Rip the disk using Disk2vhd from Microsoft Sysinternals .
• Mount the vhd in the file system of the Hyper-v-host. (i.e dubble click the vhd).
• Download and install AOMEI Partition Assistant .
• Start AOMEI Partition Assistant and select the VHD-disk which appear as an ordinary disk. Mark the disk av select to convert disk to MBR-disk from the Disk-menu.
• Remove all partitions that contains recovery disks and other non Windows partitions.
• Detach VHD from HOST (Restart may be necessary).
• Create a new Virtual Machine in Hyper-V Manager and use your modified VHD.
• Boot VM from Windows Installation disk an go to recovery console and select command prompt.
• DISKPART (to open the partition utility),
• LIST DISK (disk number(s) will be shown),

I realize that this is an old thread, however . . .

Steps 9 and 10 above by g2mk worked for me when I needed to slide a Win81 partition to the unallocated space at the front of the drive, because . . .

I originally had XP in partition0, then I installed Win81 (aka Dual Boot) and it installed Win81 to partition1. Btw, there's a procedure to remove the old Microsoft partition0 OS elsewhere on the web (says for Win7)(btw,you can use gparted to set Win81 as Boot, which equals Active via Diskpart). Then I used Gparted to slide the Win81 partition over the unallocated space. Then I needed to use Steps 9 and 10 above to get rid of 0xc000025 on winload.exe and be able to boot into Win81 on the HDD.

Btw, unless I'm missing something, everyone should note that as written, these procedures are for Windows installed on a MBR disk (ie. not for Windows installed onto a GPT disk on UEFI hardware).

• Welcome to Super User! On this Q&A site we try to provide good answers to questions people post. Part of a good answer is including all the steps required to making your answer work. Referencing to someone else's answer by saying 'above' isn't enough because the order of answers on Stack Overflow is not fixed. Please include the steps you are referring to in your own post. Providing credit by linking to the answer you're referring to is never a problem, of course! –  Cas Oct 10, 2016 at 13:43
• This bit of your answer is why I upvoted it: " everyone should note that as written, these procedures are for Windows installed on a MBR disk (ie. not for Windows installed onto a GPT disk on UEFI hardware). " Indeed, even the answer mentioning "VHD GPT-disk" first converts VHD to MBR as there is no way that DISKPART will let you make any partition "Active" on a GPT-disk. When you have a GPT disk, follow the steps in superuser.com/a/1444266/14061 by @Nathan2055 –  Jeroen Wiert Pluimers Dec 29, 2022 at 18:09

While attempting to load Windows Server 2003 on a new drive of my Windows 7 machine, I somehow wiped out the boot on the Windows 7 drive.

Windows could not start because of a computer disk hardware configuration problem

After three days of poking around, I was able to use the following steps to correct the issue:

• Boot from Windows 7 Install Disk
• Select "Repair" Option
• Select "Startup Repair" (this will run but not find any issues)
• Select Advanced Options to get to "Command Prompt"
• bootsect /nt60 SYS
• Restart the computer normally

• This is an answer to a different question ... –  DavidPostill ♦ Nov 19, 2016 at 11:05

Make Partition Bootable in Windows 10, 8, 7 Using Diskpart OR CMD

In any case, the partition contains bootable data, sometimes the system may fail to detect it as a suitable partition. This is owing to the fact that, to be recognized by the PC as a bootable partition, the partition does not require a bootable environment, it only needs to be marked as an active system partition.

Users can add the active marker to the hard drive partition using Diskpart, a command-line disk management application built into Windows. Therefore, in the upcoming section, we are going to discuss a manual procedure to understand how do I make a partition bootable in Windows 10. Before that, let us know about the boot partition in a clear way.

Notes:- Fix External Hard Drive Not Showing Up in Disk Management in Windows 10

What is a Boot Partition?

For Windows OS including XP, Vista, 7, 8, 8.1, or 10, a boot partition is a partition that holds necessary files. In fact, the boot partition is also considered a boot volume. Whenever users install other Operating systems, for e.g., Windows Vista if they already have Windows XP installed or next Ubuntu already installed Windows Vista, then they must have to contain two partitions, i.e., dual-boot or multi-boot configuration.

Extra Tips: We all are aware of the importance of data, So it is highly recommend that first sucre your data and then perform steps to make partition bootable. Download computer data recovery software. Download Now Buy Now

Manual Methods to Make Boot Partition in Windows 10

Perform the methods to make HDD partition bootable in Windows 10, 8, and 7 either using the command prompt (CMD) or diskpart.

Method 1: – Make Partition Bootable Using Diskpart

Before executing the steps, first, you have to install Windows 7 and use Disk Management from Windows 7 for creating a boot partition and after that, install Windows 10. Also, you can use Disk Management for Windows 8 to install Windows 10 OS on a new partition. Follow the below steps to make the boot partition in Windows 10:

• First of all, boot into Windows 10
• Open Start Menu and type diskmgmt.msc to access Disk Management
• Click the OK button or press Enter key
• Check if you have the unallocated space on the hard disk. If so, then right-click on unallocated space and click the New Simple Volume . In case, if you do not have any unallocated space, you can shrink the volume Windows 8 already uses. For this, right-click on volume and click the Shrink Volume .
• Continue with instructions to accomplish the process

Method 2: – Make HDD Partition Bootable in Windows Using CMD

Go through the following steps to make the partition bootable using the command prompt:

• Open the Windows screen and after that, type cmd . Right-click on Command-Line Prompt and choose Run as administrator
• Now, type diskpart and press the Return key . Now, the Diskpart will launch. When the Diskpart is active, the traditional command prompt will be replaced by Diskpart prompt, identifying a command you enter will be processed by an application
• Enter list disk and again, press the Return key. You have noticed that the number assigned to a drive that contains partition you want to make bootable . You can find that particular number in the first column
• Mark select disk X , replacing X with the number assigned to a suitable drive. Now, press Enter key
• Type list partition and press Return key. Consider the number assigned to a partition that you wish to make bootable
• Enter the select partition X , replacing X with a total number of the partition you wish to select. Press Enter key.
• Type active and press Return key to require Diskpart to mark that bootable partition as active
• In the end, select Exit followed by Return key, to close the Diskpart. Now, you can close the Command Prompt window

How to Make a Partition Bootable With DiskPart

Even if a partition contains bootable data, your computer might sometimes fail to detect it as a suitable bootable partition. This is usually due to the fact that, to be recognized by your computer as a bootable partition, a partition does not only need to contain a bootable environment, it also needs to be specifically marked as an active system partition. You can add that active marker to a hard drive partition by using Diskpart, a command-line disk management application that is built into Windows.

Windows 10 does not boot. No partition in system disk

I guess my system disk somehow got corrupted...

Short story of the issue:

I left my PC locked and when I returned I found it with BIOS opened.

When I tried to restart it, it was always entering BIOS.

I tried troubleshooting the issue from windows installer but it failed to find the issue.

I tried searching for possible solutions but I could not complete any of those because somehow my system disk is not identified as system.

If I go to cmd in windows installer and enter diskpart, select disk where windows are installed and enter "list partition" I get "There are no partition on the disk to show" message.

The only idea I have now is to reinstall windows, but that would delete all the data on my disk which I would like to avoid.

Is it possible somehow to fix this issue?

Hi, thanks for response.

Start up repair fails, so I've tried other steps.

The /fixmbr seems to succeed, however

bootrec /fixboot produces element not found

bootrec /scanos and /rebuildbcd fails to identify any installation.

to identify installations the link that you posted suggests running these commands:

bcdedit /export c:\bcdbackup attrib c:\\boot\\bcd -r –s -h ren c:\\boot\\bcd bcd.old bootrec /rebuildbcd

But the first command produces "The store export operation has failed. The requested system device cannot be found"

I'm not sure about the first step

After running "diskpart" and "List Disk" I ran "diskpart sel disk 0 list vol" but the command was not recognized.

Instead I ran Select disk 0, and then list volume, I hope this achieves same behavior?

I could then see some of my volumes listed but non of them had column Fs with FAT32 entry, only UDF and NTFS

One other strange thing that I'm seeing:

My PC has a dvd-rom, an SSD drive which has windows installed and extra HDD drive.

When i run "disk list" in diskpart, Disk 0 (111 GB) and Disk 1 (931 GB) get listed, based on the displayed size I assume that Disk 0 is ssd drive and disk 1 is hdd drive. (Also strange here that Disk 1 has 0 free space and "Disk 0" seems to be empty (its' free size matches its' full size))

After I enter "List volume", two volumes get displayed

Volume###       Ltr     Fs      Type               Size

Volume 0           D      UDF   DVD-ROM     4136 MB

Volume 1           C      NTFS  Partition        931 GB

Shouldn't there be another volume listed here? That would represent SSD drive which has windows installed? 

Also, not sure if that helps or is related but, My system drive where windows are installed should be named as "C" but in list volume I can see that Volume 1 has letter "C"

Repairing EFI/GPT Bootloader using the DISKPART and BCDEdit command

This guide helps repair bootloader issues, for example getting a blue screen of death with the following error:

c.f. http://woshub.com/how-to-repair-uefi-bootloader-in-windows-8/ for more background information.

Use diskpart to make System partition available.

(This will allow us to use bcdedit later in this guide to repair the bootloader.)

Boot from the Windows installation media

When at the Install Windows screen hit Shift+F10 to bring up a command prompt.

Type diskpart , then type list disk :

Select boot disk

You need to "Select" a disk before continuing. If only one disk shows, type, select disk 0 . If there is more than one disk, they will need to verify based on disk size. If it is not disk 0 they would replace 0 with the number of the drive. (In my sample above, it is hopefully clear that '0' is the boot drive and the other two are not.)

Verify Partitions

Type, list par , to verify that there are 4 partitions, Recovery, System, Reserved, Primary.

Select volume to use

Type, list vol , the volume number they want to use in the next step will have a FAT32 file system and should be 99MB with System under info.

In this example, this is Volume 2.

Type, select vol 2 , (number identified from previous step), i.e. select vol 2

Type, assign letter=z and should see "Diskpart successfully assigned the drive letter".

Type exit (Z: drive is now the System partition)

Set up EFI boot partition using bcdedit (Boot Configuration Data editor)

(c.f. https://neosmart.net/wiki/bcdedit/#Commands_and_parameters for more info on bcdedit)

Type mkdir Z:\EFI\Microsoft\Boot

Type xcopy /s C:\Windows\Boot\EFI*.* Z:\EFI\Microsoft\Boot

Type cd EFI\Microsoft\Boot

Type the following commands

bcdedit /createstore BCD

bcdedit /store BCD /create {bootmgr} /d "Windows Boot Manager"
