Windows Vista failing to boot

[Guest]

I've been trying to get Windows Vista Beta 2 to install on my desktop however
I can't seem to coax it into working with all i've tried. I'm running a MSI
K8NGM2-FID motherboard with a nForce 7800 GT graphics card with 3 SATA
drives. For some reason I can not boot from the DVD if I place it in my
drive, instead it just suddenly resets my system. If i try to install it from
WinXP it will do whatever it needs to in windows reboot then when it tries to
read the drive afterwards it just suddenly reboots again without any notice.
This forces me about 100% of the time to launch the recovery console off my
XP disc to repair the MBR and boot sector before I can get back to Windows XP.

Specs:
MSI K8NGM2-FID motherboard
eVGA geForce 7800 GT
1 GB DDR400 ram
AMD Athlon 64 3200+
USB-External Memorex DVD-/+ RW burner
3 SATA drives (Mix of WD and Seagate)

I did check the Upgrade Advisor and it stated that the "NVIDIA nForce PCI
System Management" requires me to install them manually but says they exist
but if its required to install, how do i give it to Vista before it begins
it's install? Could this just be a case of a missing driver or am I actually
sitting on some incompatible hardware for this beta?

What version of xp do you have?

I'm running Windows XP MCE 2005, the most recent OEM kit.

You may need to use an internal DVD-rom instead. I think Vista loses access
to your USB dvd-rw drive when setup starts.

Try this to confirm it: If you run Vista setup from within Windows, after it
reboots but before it loads (before the moving progress bar) take out the
installation dvd. You should be able to progress further through setup until
it needs the disc.

I've actually turned off the drive all together after running the install in
Windows to attempt to see if that was the problem. Normally in windows, if
the drive or install disc isn't there, it should come up with a boot menu of
sorts but for some reason it just reset without any other notice. I'll see if
I can rig some sort of IDE connection to an internal unit tonight. I don't
have one in the PC itself due to a problem with the power supply sticks into
the space where my CD/DVD drives should sit.
