Answer 1

Recover from a crash For reinstalling your operating system Try tapping F8 on boot up then use arrow keys to scroll to last known good hit enter (Without Disk in the ROM drive)  

Answer 2

Try pressing escape rapidly when booting, or F8.

Your goal is to get to a screen that says "Choose boot type" or something, and lists CD/DVD, Hard Disk, LAN, etc.
