I'm quite sure that F8 gives u the options to boot in safe mode, vga mode etc.
But to boot from the cd u need to go to bios and change the boot priority.
And for the partitions u can just delete it after booting from the cd, when reinstalling it comes to a part where it shows the partitions and asks to which one u want to install windows. Then just delete the partition u don't want there and make a new one.
