V strange problem below, grateful for any suggestions!

I’ve created a new partition on my primary HD to install Vista. The HD now has 2 partitions one with XP and one with Vista. If I set my bios to boot from CDROM drive first and there’s a disk in there, I get a boot up prompt to press a key to boot from CDROM. Assuming I don’t press anything I get the Vista boot manager popping up as it should allowing me to choose from XP or Vista, both of which work fine.

If however, I turn off boot from CDROM first (ie boot from HD first as you would do normally to speed up booting) then the boot manager never appears and XP loads up straight away.

Anyone got any ideas on this? I thought it might be something to do with XP being installed on the “active” partition hence XP boots by default? My reading is that Vista should take over the booting process regardless so not sure why I’m getting the problem above.

I’ve tried all the suggestions on repairing the MBR etc but this problem seems to be linked to the BIOS.
