About a year ago, I was preparing to copy files from multiple computers I used into one. Both machines were Windows 7 while the target machine is Windows 10.
tl;dr, Windows 10 fast boot will damage/corrupt Windows 7 drives.
One of my machines survived the process though it refreshed the User Profile on boot. The machine I'm working on now is less expedient in its return.
Last I left it, it wouldn't finish a Startup Repair even after hours of waiting (1 TB hdd 7200rpm). I went in with Parted Magic to see what the partitions looked like (couldn't remember if the whole thing was jumbled). The partition viewer reported in the C partition:
$MFTMirr does not match $MFT (record 0)
and said I should run CHKDSK /f as it would be the best at it.
I restarted and entered the system repair command prompt and ran CHKDSK /f which I hoped would return some normalcy. The CHKDSK failed at 57%. The message at the end was
an unspecified error occurred <696e647863686b2e e19> failed to transfer logged messages to event log with status 50
I ran it several times and it would have the same issue at the same %, give or a take a few records (Verifying Indexes stage 2/3, 2488728 of 2774856) and always around 2488000+).
Some googling said that the partition could be locked or that I have drive errors (ran a quick drive check in pmagic and it came back ok). I opened up DISKPART in the CMD and tried to clear any readonly flags for C but DISKPART said it failed to clear flags. I don't know if there just weren't any or something else was going on.
Some websites said to go into safe mode and run CHKDSK and I tried that but safe mode won't go any further than loading drivers and giving me a black screen with the cursor. I can move the cursor but nothing else happens. I've tried safe mode and safe mode with command prompt.
My question today is "How do I safely reenter Windows 7 after possible file corruption from Windows 10?"
I would preferably like to complete one round of CHKDSK before booting normally.
Additionally, I have available a copy of the HDD from a year and a half ( a little over half a year ) before my initial file copy with Windows 10.
I have the time and some decent technical skill, so I'm all ears.
Edit, Update post 2 hours: I hit "Start Normally" just to see where that would get me, and it ends up the same as safe mode, but it knows my power settings as pressing the power button goes to sleep, which is what I set it to long ago.
Edit, Update post 7 Hours:
I ran ntfsfix /dev/sda2
( sda2: the main partition) while in Parted Magic for the $MFT
message it had given. Other than a few attribute edits, CHKDSK reached the same index and stopped. The index number it stops at changes but not more than a few hundred in either direction. I tried to run sfc /scannow, but it wouldn't run as it needed a system restart. Tried to delete the pending.xml but it reported back as corrupt and that I needed to run chkdsk. I ran chkdsk just before this so I am nearly at a complete impasse.
Edit, Update post 8 hours: Forgot to delete pending from X: as well. Deleted pending in C using Parted Magic. SFC ran but found nothing wrong.
Edit, Update post 30 hours: Chkdsk finished Index verification this time around, probably black magic from using pmagic, or that I'm using a Windows 7 disk instead of recovery partition (which may have errors I don't know about yet).
Edit, Update post 3 days:
After indexes verified (chkdsk), there were alot of Replacing invalid security id with default id for file ####### of 2207744
messages. Windows still boots into a cursor and black screen. The commands sfc /scannow /offbootdir=C:\ /offwindir=C:\windows
reports that "Windows resource protection could not perform the requested operation". No % verification is ever reported, just that it began and will take time. DISM didn't work either from the Win7 disk I used, and the Win7 PE environment doesn't contain DISM. I'm thinking the profile system is corrupted or something. More info would be nice.
