FC18 LiveCD

Hello all,

I am trying to use the FC18 liveCD on my HP dm4 laptop. The problem is when i try to boot using the liveCD, my laptop screen remains blank and no matter what key i press it remains blank.

I went into troubleshoot option selected boot with basic graphics however its no use the screen is still blank. Btw this laptop has dual graphics card, Intel HD3000 & Ati 5400 mobility radeon.

No idea what else i should try.

Any help is appreciated.

Thank you.
