Windows 10: Partition Missing on Hard Disk

I was trying to install a Linux partition a few days ago but I decided to back out of the whole thing mid-process, but I had already partitioned 50 GB of my 512 hard drive from the Windows OS in my hard drive knowing I had enough free space to do so. Upon returning to Windows, I saw in storage in settings that it said my OS was 474 GB, which made sense as I had partitioned 50 GB off of it. I figured that the ~50GB partition would show up in disk manager as I have partitioned my hard disk before and simply added the non-allocated 50 GB onto the OS partition by extending the volume in disk mana

W7 Hard drive partition issue

to get rid of that 100 meg windows partition that setup creates for you on a new install on a blank hdd:

- press shift+f10 when on the partition management screen in setup <-- this opens a command prompt
- diskpart <-- start the windows command line partition management tool
- list disk <--- list the installed hdds in this computer for the next step
- select disk 0 <- might have to replace 0 with the number of the correct disk
- clean <-- this will erase all data on the disk you selected one step up- dont use the wrong disk!
- create partition primary <- creates a primary partition taking up all space on the drive, adjust the command if necessary
- exit, exit to exit diskpart and the command prompt
- click refresh in partition manager and select your newly created partition and install to that

 

Hard disk partition not showing up.

Hi Muhammad,



Thank you for writing to Microsoft Community Forums.



This can happen if the Hard-disk drivers are not up-to date. I would suggest you to update the hard disk drivers first. To update the drivers, please follow the steps mentioned below:

1. Open Device manager.
   
2. Then Expand “Disk drives”.
   
3. Then Right click on the Hard-disk listed under this category.
   
4. Then click on Update drivers.
   
5. Alternatively you can also try to update the drivers from manufacturer’s website.
   

Once the hard-disk drivers are updated, you will need to allocate the last partition (it is not allocated according to the screenshot) and you will be able to view the partition.



Also note that sometimes the hard disk partitions/drives might be hidden in This PC or My Computer window due to a Registry key. If a DWORD with the name NoViewOnDrive or NoDrives is present under following key in Registry Editor:

HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Policies\Explorer

Delete the DWORD and your drives will become visible in My Computer window.



Hope this helps.

 

how to add a portion of disk into another hard disk partition in windows 10?

Hi Hamiul,

I realize the inconvenience you are facing. Let me help you in resolving the issue.

I suggest you to follow the steps below and check if that helps.

• Run Disk Management. Open Run Command (Windows button +R) a dialog box will open and type "diskmgmt.msc".
• In the Disk Management screen, just right-click on the partition that you want to shrink, and select “Extend Volume” from the menu
• Locate your system partition — that’s probably the C: partition. Right-click on it and select “Shrink Volume.” If you have multiple partitions on your hard drive, you could also choose to resize a different partition to free up space.

Hope the information helps. Please let us know if the issue persist and we will be happy to assist you further.

Thank you.
