Windows 10: CHKDSK might have broke my partition

My old hard disk was fully broken, when I plug it in it makes the computer almost frozen.But I repaired the hard disk with good percentage to only restore the data.The disk was working very good, yes sometimes it freeze but at least working and I took some of my old data copy and it worked.I wanted to defragmentation to make the disk better, but I saw that it have dirty bit or something like that so I tried chkdsk to solve that.But chkdsk broke my partition!Now my partition is defined as "RAW" but when I use chkdsk again, it restore the partition name and say it and partition file system type

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

 

How do I run CHKDSK on EFI System Partition?

On Windows, I used DISKPART to assign the EFI System partition a letter. Fired up DISKPART, and typed LIST DISK to find the disk, followed by SELECT DISK <N> (where is the drive number). Followed the same steps to find the proper partition (i.e. LIST PARTITION followed by SELECT PARTITION <N>), and then simply typed ASSIGN LETTER = X to have Windows mount the partition to letter X.

Then opened CMD with administrative access. Ran CHKDSK X: /f /r

Then, I tried installing Ubuntu once again, and it installed successfully!

 

chkdsk c: /F

It might be an error on the drive. We suggests that you follow the troubleshooting steps below:

• Run Disk Cleanup utility to clear your junk files.
• Open an elevated CMD type sfc /scannow and hit Enter to run the System File Checker.
  
• Once the scan is completed, restart your computer. Remember to exit ChkDsk
  during boot.
• Next, again open CMD as admin type
  Dism /Online /Cleanup-Image /RestoreHealth and hit Enter to repair the Windows image.
• Now see if ChkDsk able to complete the scan.

Note: Before doing the steps, make sure you save a back up of your files.
