My son's Acer E5-551-T1PJ Windows 10 laptop crashed while playing Steam yesterday. Screen went black while gaming, rebooted, then immediately "No Bootable Device".
There's nothing important on it so now I just need to Reset Windows 10.
What I've tried...
Tried resetting from boot screen repeatedly (both options). Each time got to 80% then failed and reverted.
Login screen tells me there's no saved restore points (even though there should be.)
If/when it gets as far as letting me login,
Explorer.execrashes immediately:There's no taskbar or start menu but hitting CTRLALTDEL and Task Manager slowly loads, and from there I can manage to get an elevated command prompt.
Task Manager says Disk Usage is at 100%, but only 0.3 MB/s is listed:

Memory Tests
I was finally able to run a Windows memory test (MdSched.exe at the command prompt) and a Linux memory test (from the GRUB screen)...
- No memory problems found.
CHKDSK /F
Apparently this error means:
...there are corruptions or bad sectors in Windows partition Run
chkdsk c: /r /f /vto repair system partition.
(I began a CHKDSK /R before I found that, but looking at the docs I'm not convinced the extra switches will make a difference.)
CHKDSK /R
CHKDSK C: /R Bad Clusters Repaired (Click to Englarge)
After about 8 hours it finished, and had found & repaired a few dozen bad clusters. I ran it again to confirm there was no problem.
...but it still won't reset. It gets partway done and then "has a problem" and reverts...

sfc /scannow
Finished Verification 100%, and then:
Windows Resource Protection could not perform the requested operation
CHKDSK /R /F /X again
Attempt #3 powered itself off halfway through.
Attempt #4 is about 4 hours in:
SFC /scannow
Verification 100% complete.
Windows Resource Protection could not perform the requested operation.
Any guesses at the diagnosis? Memory vs Disk?
Is there anything else I can try using only the command prompt, recovery menu, or Linux?
Will creating a recovery drive in a USB thumb drive have any more chance of working than already the failed Reset attempts?
...any other suggestions to save this poor single dad a few hundred bucks at the repair shop?!
