No Bootable Device and BSOD
Posted on 2008-10-16
A friend installed SP1 on Vista Home Premium last night. This was after the computer was restarting itself several times throughout the day. He suspected that the service pack may be the cause of the restarts. The SP install went fine, but then his computer would not boot. Instead it returned this error:
no bootable device--insert boot disk and press any key
The hard drive is visible in BIOS, if that means anything. I inserted the Gateway Windows Operating System CD that came with the computer and tried to boot from that. Booting from the CD yielded the following blue screen error:
worker thread returned at bad irql
What does this mean, and what should I try next? Thank You.
