[help] WinXP boots only with CD

[mar_tin]

Heya, my 1st post here

I have some weird problem, Windows XP boots only when the Windows CD is in the CD Drive (I haven't tried with other CD's). Otherwise I get the Boot error as if there is no OS on the hard disk. I created an unattended version with nLite, and I added some custom tweaks. It installs and works with no errors. Does anyone have a clue what could be the problem?

Thank you

Martin
