Are you dual booting Win7 using XP on 2 different hard drives?

    If you are can you confirm if installing Win7 on a second (unformated) harddrive will still mess up XP. Also, do you still have to label the main hard drive to a drive letter once you install win7 on the 2nd hard drive?

    unplug the XP drive first, so that it doesnt mess with the boot block.

    Then use your BIOS to choose what drive to boot.

    That way each OS beleives that its OS is the C: drive, and you can just change the drive letters for the other OS as you see fit.

    The only thing that can format a HDD thats unplugged, is a big magnet.

    I have XP x64 installed on 1st partition and Vista on the second Partition of a raid 5 setup and both working great.

    The reason i install XP 1st as i will likely use that more than 7 like i did with Vista. And if 7 fucks up i can just format the second partition lol. O yeah XP don't mess up on me it's been sweet since i got it which is another reason i put XP on 1st and on the 1st partition.

    Anyways no problems here at all.


    I formated the 2nd partition from XP and just booted up the win7 DVD and installed it to the second Partition. As long as your boot order is right should be just fine.

    asrock: since you installed 7, the bootblock has been changed. Depending on what HDD that bootblock is now installed to, you could have an unbootable system removing either OS

    (If bootblock is on 7 drive, formatting that drive will make your XP unbootable, and vice versa)

    Can I just clarify how this is done.

    Install new hard disk.

    Disconnect current hd with xp.

    Insert win7 cd and format install in new hd.

    Then connect hd with xp back up.

    When booting, go to bios and select boot order.

    Is this right?

    Would I have to change the boot order every time I want to switch to the other os?
    Does this also work with Vista and xp on seperate hd disks?

    I'm hoping Mussels can answer this.

    Tye

    Well by reinstalling XP will kill win 7 anyways. And the older win 7 i deleted and put vista in it's place without issue now it has win7 on it once again lol..


    Thanks for the info though, i'll just back up xp stuff before getting rid of 7 if needed.

    Optional. havent you ever installed windows before? you always have a choice to partition and format.


    yes thats how i do it. It works with as many OS's as you have Hard drives.
    Most modern motherboards have a hotkey, instead of pressing delete to go into the BIOS, you press ESC, F8, F10 or F12 (it varies... annoyingly. check your mobo manual/google) and it gives a list of bootable devices.


    A repair install usually fixes it. Lots of people tend to screw up repair installs and format accidentally (cough my brother cough), so i find it best to warn them in advance.
