I am totally out of ideas here. I have a all NEW Biostar MCP6P M2+ mobo and a gig ram and decent amd processor. I have 2 used 160gb drives that I have run Darik's boot and Nuke on with no problems. Here is the problem I install the OS from a legit Window$ CD and it installs fine no problem but then it goes to reboot after the install and then it just hangs there with a flashing " - " or if the CD is in the drive it just stops at "press any button to boot from CD" and never does anything. I have the bios set to boot from cd first then HD second so I tried setting it to HD first and same thing. I checked and I do have the HD set as master and nothing else on the cable.
Things I tried:
used only 1 HD and 1 CD Drive
Used a SATA drive then tried a IDE drive
reset the CMOS
changed cables both the IDE then SATA
Tried Windows 7 then formated drive and tried XP on both drives.
