I have a new H67 Sandybridge computer I put together. I installed Win7x64 as my main operating system. On another harddrive I used Win7 disc manager to partition a 750GB harddrive. I made one partition 20GB with plans to install XP for dual booting, the other partition would be used for storage. WinXP won't install on the hard drive. I set bios to boot from the DVD with second boot device being the 750GB harddrive (the bios doesn't see partitions, just entire harddrives.) The WinXP will load files, etc, then when it gets to starting windows gives a blue screen saying I have a virus on my harddrive or it is corrupt, run chdsk. I tried partitioning the harddrive with parted magic boot cd but then Win7 doesn't recognize it. Any idead how to make this work?
