Boot off a CD-ROM? Could do?

_____________
Can do easily.

Hit the key during startup that enters the BIOS setup and put the CD-ROM
ahead of the hard drive in the Boot Sequence. On my Dells it's F2 before the
self-test completes. F12 lets me select any bootable source for this session
only.

My Lenovo laptop is a little different. It came in a Fastboot mode that
bypassed the chance to enter the BIOS.
