Imaged but no boot

[TechSupp]

Just come to the last PC to be imaged (all same image and syspreped), imaged other PC's fine, booted installed etc etc, the last one imaged it but it just wont boot from the drive, its in bios etc It just goes through all the boot options then starts again. Did have xp on before now shoild be w7. Its a NEC ML450 (not my particular fav and less now!) All rest were fujitsu. Thinking its the drive not marked as boot (had once before with a samsung) how can I check/set boot flag? Usually use sysrescuecd but of course its at home! Or is it something else?

Just checked and first 100mb partition is marked as primary and active as viewed in partitionmagic.

Job sorted, it was a bios upgrade that was needed, just need the audio controller and job done!

I am having the same issue where the NEC ML450 won't accept any other OS apart from XP and see TechSupp solved it by doing a BIOS upgrade but I have never upgraded a BIOS before and if mess it up, the PC becomes unusable. How do I update the BIOS on a NEC ML450?
