win 10 drive error

I constantly have the notification to restart fix drive error. it never goes away. ran advanced repair said could not fix. running 10. no of course no back up. wanted to go back to win 8 but cant, and there are no stored files to go back to in restore. actually went a bought the win 8 installation disk ($130!) confirms key then shuts down, says cant install
so how can I get it load my win 8 installation from cd?

First try chkdsk, have to schedule it on next restart. (Admin) Command Prompt copy and paste this, press enter

chkdsk c: /f /r

Then try this at admin command prompt copy and paste this press enter, let it finish
sfc /scannow

After at the same open command prompt, copy and paste this and press enter, let it finish, reboot PC after it does
dism /online /cleanup-image /restorehealth


How did you try to go back to Windows 8, through Advanced options recovery ?

it wouldnt let me go through advanced recovery - wouldnt recognize drive - actually i did finally get it installed. i had to go to "compatibility" and revert to win 8, then i was able to install but even though everything on computer was wiped out only 10 of 139 used its sooo slow

Not sure what you meant by go through compatibility to revert back. You bought now a Windows 8.1 disc, that what you tried to install right, because your saying revert ? Possibility Hard Drive has issues without trying any of suggestion you went back to trying to reinstall Windows 8.1. Hard Drive could be failing, have bad sectors on the drive or can be issue being recognized by PC.

Hard to be sure as i do not have all the details and the specs of system. Other options we could of tried while still with Windows 10, but you went further now by trying to reinstall older OS back assumed with the new disc.
