Windows 10: acpiex.sys corrupt

ok still looking up options.
All DISM commands fail in re is that correct?
DISM /Online /Cleanup-Image /RestoreHealth /Source:repairSource\install.wim
DISM /Online /Cleanup-Image /RestoreHealth /Source:C:\$Windows.~BT\Sources\Install.esd

IF i remember correctly the DISM dont work with X:

Error 50
DISM does not support servicing windows PE with the /online option

Re the bootable rescue disk link, I take it I would need another machine on hand to download and write this dvd if so will and old xp machine work?
Also, are there some reasonably idiot proof instructions on how to proceed amongst the 101 pages of at thread? :-)

thanks very much much for all your help

yes you have options with a bootable windows 10 iso: Download Windows 10

In the windows advance recovery menu you were able to test reset, restore, startup repair

What happens when you select startup options?

Reset and Restore don't work nor does Image recovery. Startup Repair fails and points me to error log. Startup Options (Settings?) allows me to restart to view the various further restart options but none of them do anything. See my post 6
thanks

Sorry, but I don't really understand how to proceed with Kyhi's Custom recovery disk thread. Are there idiot proof instructions somewhere in the thread?
