I hibernated my Lenovo G770 laptop (H2O Insyde Bios, Windows 7) last night with a USB hard drive attached. On trying to resuming this morning I get the error:
Windows Boot Manager
Info: The boot selection failed because a required device is inaccessible.
I suspect that this may be related to the USB hard drive, which is powered on and attached. I've tried to boot with/without the drive, also tried to boot the Windows recovery CD and Debian Live USB stick, but none of them work and I cannot get into the bios to alter the boot order (Have tried all the f* keys). When trying to enter the bios I just end up at the Windows Boot Manager, presumably because the system is trying to resume from hibernate all the time. If I press the space bar during boot then the only boot option shown is Windows 7, no option to drop the hibernated version and restart.
HELP, I need this machine for my work. Can you suggest what I might do next?
