My daughter's laptop has stopped booting into Winodws Vista SP1 32 bit. It gets past the Dell BIOS screen and starts trying to load Windows, but sticks at the small rippling bar at the bottom of the splash screen, just before the Windows logo appears. This rippling bar just goes on and on.
I've tried starting it in Safe mode, but the scrolling list of drivers gets as far as Windows\system32\drivers\crcdisk.sys then stops.
I've tried Last Known Good Configuration - nothing happens.
I've restarted the computer with the Dell operating system disk in the optical drive, in order to run a repair. But the computer won't boot from the drive - it just goes to the startup options menu again.
The Dell BIOS screen has no indication of what key to press, in order to get into the BIOS and change the boot order to the optical drive. I've tried every key I can think of - F8, F10, F11, Esc... and so on. Nothing will persuade the computer to get me into the BIOS.
Any thoughts on how I can get the computer to boot from the OS disk, please?
