    Dual HD


    I have windows 8 on a new dell and would like to put in another hard drive from my old computer that has win7 on it...I hooked it up (two plugs, easy) but when I turned the computer back on it immediately went into "starting repair" so I chickened out, shut the computer down and unhooked the other hard drive.
    I'd really like to have both of them there so if I'm having problems with one I can just restart into the other....should I let it do the repair? What is it trying to repair? I don't want to screw up the new hard drive.

    You need to delete the Windows 7 install first. Than both HD Drive will work.

    And then reinstall it? I want an OS on each drive.

    I personally would keep the Windows 7 install on the old PC, for now.

    I can understand that....not liking windows 8 but can't have two computers running (space is TIGHT and too much of a pain to unplug from one and plug into another, all the cords are hard to get at).....That's why I'd really like to move the HD into the win8 computer....then I can switch over easily. Any work arounds? Should I not let it "repair"? Obviously I don't want to screw up win8.

    As a guess:

    1) If you removed the Win 7 drive from another PC, then surely the drivers, etc are going to be for the other PC, not this one.

    2) If you just plugged the Win 7 drive into the PC's second drive bay, then the Win 8 drive is still plugged into SATA0 and the Win 7 drive is going to be plugged into wherever Dell ran the second drive SATA cables to (probably SATA 3 or 4 on the Motherboard). Therefore, the PC will presumably still try to boot from SATA0 (the Win 8 drive).

    You can turn off SATA0 (Win 8 drive) and enable SATA* (Win 7 drive) in BIOS, therefore it can't try to boot from the Win 8 drive. But, as in 1 above, I'm not sure if it's recommended as the drive wasn't intended to be the boot drive for your PC when Win 7 was installed on it.

    Personally, assuming you have a valid licence key and installation disc for Windows 7, I'd back up your files, format the disc and re-install Win 7 on that drive from the PC you're going to be using it on (plugged in to the primary SATA cable). Then you will have Win 7 on one drive and Win 8 on the other. Depending on which drive you want to boot from either remove the side panel of your PC and swap drives, or if they're both plugged in to separate SATA ports, disable the primary drive in BIOS before booting so that it boots from the other drive.

    If your Win 8 PC has UEFI, then I've no idea as I've never used it.

    All new Windows 8 Pc's have uEFI & Secure Boot,

    Windows 7 not install with Secure Boot.

    Boy, I can't win can I. Sigh. Guess I'll keep it in the other computer and throw it (not literally) down cellar and if in emergency I need it I'll have to go from there. SEems like too much trouble to try to do above (if it can even be done)...so here's another question, I also have a smaller drive that I installed win 8 pro on a few weeks ago when it first was offered for cheap...what if I connected that hard drive as a "2nd" instead? Would that work?

    The above will not work.
