I just brought my parts for my new computer and build them, they were:
MSI P55 GD65 Motherboard
G Skill Ripjaws 2GB (x2)
XFX GTS 250
LITEON 24x Iinternal DVD/CD Rewriter
Seagate Baracuda 320GB HDD
Thermaltake Xaser VI MX
Anyhow, it boots up and I am able to access the BIOS menu.
I set the CD/DVD drive as 1st in the boot order.
But I cannot boot from my XP CD.
It comes up as this "Reboot and select proper boot device or insert boot media in selected"
I've even tried taking out my old DVD drive out of my older computer (Which i've used to install XP) and it still didn't work..
What are your BIOS settings for the DVD?
Are you certain the DVD connectors -to power and mobo - are good? You might try different cables - maybe the SATA cable (is it SATA?) is bad. Try a different power connector too.
If you have any USB devices connected - disconnect for now.
i got to be the CD/DVD copy of the windows, same happen to me with a old DELL pc, i couldnt get the cd to work, then again it was an ISo.file i created, the my friend lend me his Vista DVD and worked like a charm.
