I have recently bought a thinkpad x24,when i turn it on it says operating system not found,so i have connected via usb an external cd rom drive and rebooted only to be stuck at the same black screen with "operating system not found" i have only the cd drive and hard drive selected to boot and have diabled the network,other devices so that it will only look at the cd and hard drive but i still get the same answer,could this be a hard drive problem?

When i restarted the system i pressed esc to take down the following details but i dont know what they mean :

details are:CPU iNTEL PENTIUM M PROCESSOR 1133 MHZ
638 K SYSTEM RAM PASSED
382M EXTENDED RAM PASSED
512K CACHE RAM PASSED
SYSTEM bios SHADOWED
UMB UPPERLIMIT SEGMENT ADDRESS:dc00
usb :tEAC CD-224E
fIXED dISK 0:HITACHI_dk23da-30B
mouse initialised
then it goes blank screen and operating system not found even though i have a proper version of xp pro in the cd drive.

any help would be most appriciated.
