I did a fresh install of windows 8.1 (pro x64) on a spare laptop of mine a while back.
I thought of upgrading it to windows 10 (pro x64). When I try to upgrade everything goes smoothly until the screen where there is a big dial in the center. It goes to about 35% and the status of copying files is at around 75% and the system restarts. After it restarts a screen appears which says Restoring your previous windows and I get an error message 0x80070b7 (or something like that) which says something of this sort 'Windows 10 installation failes in SAFE_OS phase PREPARE_FIRST_BOOT'.
If anyone can provide some steps I'll be grateful, I have'nt had any luck googling about it.
TL;DR Want to upgrade to Windows 10 but cannout due to PREPARE_FIRST_BOOT Error
Thanks.
