I don't go into Win7 very often since I ( well, you guys helped me a lot ) created a dual boot system with Win10, but when I do chkdsk starts to run on all my drives (x7 drives).
After that when I boot back to Win10 I get a disk repair scan and fix....What on earth is going on? and is Win7 ( on a seperate drive ) messing with the ssd with Win10 installed?
When windows starts up it writes a dirty bit to the disks when it shuts down it clears it if on boot it finds its set then it runs a disk check Manually Reset or Clear Dirty Bit in Windows without using CHKDSK • Raymond.CC
When I had the same problem [on a dual boot, mine was Win10-WinXP], I only fixed it by running ChkDsk with these switches
NotesCode:chkdsk C: /F /V /R /X
- I aways worry about ChkDsk messing up my own files so I do a full backup before running these intensive scans
- My example shows C:\ being scanned.
- I ran it for F:\ as well - that was the drive letter for the other OS drive as it appeared in this one
- You can see the meaning of those switches by entering ChkDsk /? in a command window
- Afterwards, I ran fsutil dirty query C: [ and then ... F:\] in an elevated command prompt to check that the drives were no longer dirty.
- I did not note any timings but I seem to recall that these intensive ChkDsk scans took ages.
- My notes are not clear on the matter but I think I did all this ChkDsk-ing in Windows 10 only. I did not have any problems when I later booted into the other OS but I think I re-ran the fsutil checks anyway.
If this fix did not achieve the required outcome I would restore my latest system images for both OS.
Best of luck,
Denis
I would try turning off hibernation on both Windows 7 and Window 10. Hibernation is required for Windows 10 fast startup, which is enabled by default. This tends to interfere with Windows 7 booting and returning back to Windows 10. The command (which needs administrator rights) is:
powercfg -h off
Turning off hibernation saves disk space by removing the hiberfil.sys file and also helps prevent the two operating systems from interfering with each other.
Thank you everyone.
I will try the suggestions and update.
All the best
Disable Fast Startup on your W10 system.
