My father updated from win 8.1 to win 10 but kept getting an error message saying that msvcr100.dll was missing and programs wouldn't work.  He opted to roll back to 8.1 and now his machine will not load anything.  It keeps trying to "Repair" itself and he has tried all options apart from a reset - guess who hadn't done a backup!
Has anyone else experienced this and if so was there a way out?  He has no recovbery media.
The machine is an Asus X550C laptop.

I think at this point you need to backup any personal data and reinstall 8.1 using the media creation tool here. This would be equivalent to a reset. You can also try a reset after pulling the data instead of using the media creation tool. This would be a better option as all your drivers would be included but any program installed after purchase would be gone. To pull the data you can create a WinPE disk using another Windows 7 or 8 computer, Download and run Aoemi PE builder. It will let you create a bootable CD or USB flash drive. Using it you can copy files from the Asus to an external or flash drive. Another option would be to remove the drive and attach it to another computer using an enclosure or USB adapter.

I am not sure if the reset would send the computer back to 8.1 or keep 10
