My Windows 8 installation is currently refusing to boot up correctly. It appears to be stuck on the screen with the Windows logo and spinning circle. The circle continues to spin but does not do anything - even after waiting for hours.
After rebooting multiple times, it tries to perform an automatic repair. This eventually displays a black screen with a movable mouse cursor in a low resolution, but nothing else appears, again after waiting for multiple hours.
I have tried hitting F8 to try to get into Safe mode, but it tries to do the automatic repair and I never get any option to boot into safe mode. I have tried Shift-F8 as well with no result.
I have also tried booting from the installation disc. This gets me to the point where I can select "Repair your computer", but this ends up with a blue screen with movable mouse cursor as above.
As a result, I cannot boot into Windows at all, and I cannot currently perform a refresh/reset.
I've run a memory test overnight, but there doesn't appear to be any errors.
Windows is installed on an SSD and I have two other hard disks attached. System is a Core 2 Duo in an Asus motherboard (will add model when I remember it) with 8G of RAM, Geforce 460. It's possible that there was an update installed before I rebooted, but since it happens automatically, I'm not sure.
I would prefer not to have to reinstall Windows. Are they any further steps to take to diagnose/fix this issue?
