Xandros can't find CD

hi, :D my Xandros OCE 3.01 CD came in today :D from www.cheapiso.com came in yesterday so I plug in the hdd I wanted to put it on then I booted from CD and during the boot process the Xandros setup looks for the Xandros CD but it couldn't find it? is there something I can do to fix it by any chance? it just says:
Searching for Xandros CD: Not Found

--- the Same thing happens with my Vector Linux CD's it looks for the media on the disc but doesn't find it...but windows finds all my installation discs just fine

You might need to change the boot order so it boots from cd first, so press F1 , f2, f8, esc or del, when the pc starts up and change it from HDD, to CD first.

no I have that done...it just doesnt find it

Hmm... strange. Maybe the CD itself is corrupted?

no I have no idea what it is the Cd's are fine they install on other comps its just mine :?
