Just so I am crystal clear here - all you did was to run Driver Verifier; your system BSOD'd; then you could not re-boot because of the inaccessible boot device error. Correct?
If so, Driver Verifier seems to have flagged a boot driver. Go to c:\windows\minidump and see if there are any recent dumps there.
If there are, copy them to Desktop, zip them up and attach to your next post. Perm settings will prevent you from zipping in the \windows directory.

p.s. I am really lost about your drivers.
