with that boot-sb4.iso I get first the grub 2.00 menu, and after choosing Fedora 17 entry:

----------------------------------------------
Booting `Fedora 17`

Secure boot not enabled
error: failure reading sector 0x40 from `cd0Ž.

Press any key to continue...
----------------------------------------------

And it's stuck there.. pressing "any key" doesn't help,
and ctrl+alt+del doesn't work either. I have to press Reset button.

I tried burning the iso image twice to different cdr's.. didn't help.
Any ideas?
