Hello, I put together a new build with all new components and want to dual boot Win7 & XP. I read that I’m supposed to install XP first. After the XP disk loads misc components, it fails to boot into Windows to start the installation. Blue screen, stop message that indicates virus or driver or HDD problem. I tried two brand new Hitachi 7000K 2TB HDDs. I tried SATA2 and SATA3 connectors. I tried a different, known reliable DVD drive. I tried a different XP OS disk (I have three from builds I did 8-10 years ago). I searched Microsoft support and Googled the issue: my problem might be XP(SP2) doesn't include SATA drivers? My MB is ASRock Z77 Extreme6, has no IDE connections but does have a floppy connection(!). I can go look in my garage for a floppy drive and floppy disks, test to see if they still work, and try this fix. Does anyone have any better ideas? Do I need to format the new HDDs before starting the installation? I thought that would be the first thing the XP installation would have me do (partition new HDD, quick format…), but it doesn’t get to that point before the BSOD. Thanks for all suggestions!
