INACCESSIBLE_BOOT_DEVICE after upgrade from Win 7
Hi,
A friend turned his computer (Dell Vostro) on this morning to find that it had tried to upgrade itself to Windows 10. Now when it starts, it gets an INACCESSIBLE_BOOT_DEVICE blue screen and tells you to restart. I've tried changing the AHCI/ATA setting in the bios, but that doesn't help. I've also tried booting from Win 10 install media to get to the recovery environment. When I do that, it shows a screen that says that it is in the middle of an upgrade and that I should remove the media and restart if I want to continue the upgrade or otherwise do a clean install. I would prefer not to do a clean install, since everything was set up the way he wanted it and working fine before this 'upgrade'.
I've read that sometimes booting into safe mode or removing certain drivers can resolve this problem, but I can't figure out how to do either one. Any ideas?
