Dual-booting Vista and XP

ronz28 · 10-09-2007, 06:21 AM

Hello! I have been running a dual-boot XP Pro/Vista Ultimate machine for many months, having uninstalled/reinstalled countless times with no problems. I have just assembled a new PC (all new) and am unable to boot into Vista using the same method that worked for me before. The main difference is now I have a 4 disk RAID0. I went through the motions as if it were my old single disk, partitioned. XP loads fine. I boot with the Vista DVD, install to the unallocated space, the system reboots...into XP. No OS select screen.

I ran a repair install using the Vista DVD and it finds startup errors and says it needs to reboot to fix them...straight into XP again.

This has happened exactly like I've described 3 times now. Does anyone know how to fix this?

Specs:

Intel D975XBX2
Core 2 Extreme QX6800
1GB (256MB x 4) PC6400
XFX GeForce 7950GT 512MB
RAID0 (160GB SATA x 4) using Matrix

First, u have to divide (partition) ur drive into at least 2 in order to multiboot. then u have to know that u can't downgrade to xp from a higher version and if the ram is 512, i think it will lagg hard, i mean a like a whole bunch

The RAID0 is partitioned, one for XP and one for Vista. This is not a downgrade/upgrade situation, these are full install discs. I have 1GB of memory.
