    Grub should also be on MBR of sdb.

    If you can not install openSUSE, I do not understand this part.
    Nevertheless, the question should go on another thread, I think.

    You must have something in the disk MBR even if generic boot code and if so then you need to mark the root partition as bootable. In this case I think I'd put the Grub MBR there.

    Hi plesset,

    I suspect that the external hard disk is not recognised as bootable. I had much the same problem. Please check if the external hdd is recognised as bootable by "Set up" and can be included in the booting order.

    I have the same predicament, but only reversed. I didn't want to create a similar redundant post, so I pitch in here.

    I have successfully cloned Windows from my internal SSD drive onto an external disk drive (connected with USB). Both come up under grub2 and both boot up. However when I booted Windows on the external drive without grub2, it ended with a BSOD (which I was unable to read fast enough).

    Disconnecting the external drive and trying to boot the second Windows option fails. Expected since it cannot find the drive. I then concluded that this boot option in grub2 really is the Windows on the external drive.

    I have run the Windows Recovery DVD and executed both bootsect and bootrec on both drives. This enabled the Windows partition on /dev/sda1 to boot instead of grub2. Windows boot loader offered me two Windows options. I expect these where both the internal and the external Windows. The first one boots perfectly as it should. The second one boots up half way and ends in a BSOD.

    So going back to grub2. Disabled the boot option on partition /dev/sda1 and grub2 would work again. Booting up both Windows options from grub2 works. The external drive does not get any BSOD booting from grub2.

    So I am sitting with a cloned windows drive that works, but not completely. I also want it to work without grub2. I want to be 100% sure that the clone is a viable Windows drive before I delete Windows from the internal drive.

    So any suggestions? Would be nice to be able to boot Windows without grub2, but since the computer will be running linux anyway and the external Windows drive is only "allowed" to be used with this computer it does not really matter if I boot it from grub2.

    Still as I stated, since it does not work to boot alone, I am left with a nagging feeling that it is not a viable Windows drive.


    I know this problem is 50% linux and 50% Windows (perhaps), and concerning booting Windows without linux/grub2, but who else knows better about this sort of problem with Windows than linux users.


    When I have deleted Windows from the internal drive I plan to move the linux partitions to where windows where. Reinstallation is for succers .

    IIRC installation on USB drive is not supported until Windows 8.

    IIRC installation??? What is that acronym for? http://acronyms.thefreedictionary.com/IIRC

    I'm running with Windows 7. I'm not installing anything, it is a just moving Windows from one drive to another. Since I have done it successfully before, cloning Windows from one smaller SSD to a larger SSD. Now that I have installed OpenSuse I have cloned Windows out on a different external drive. I wanted openSUSE to run alone on the internal drive and if/when I had a need to use Windows I could just boot up the external drive. And booting it up I wanted to be able to do it with and without grub2.

    I recently cloned my Windows 7 disk, internal to external via usb, then
    exchanged the disks so that it wold boot from the new disk, and Windows
    refused, blue screen. It refused to boot because the hardware had
    changed and it thought it was an illegal copy (though the wording was
    not that clear).

    I solved it by making sure the "Disk identifier:" as seen by fdisk is
    the same as the value on the old, broken disk.

    If I Recollect Correctly. I never have seen other usage at least in technical Internet communication.

    I'm running with Windows 7. I'm not installing anything
    I's not about installation process itself. There are timing issues with USB drivers so booting from (or better having system drive on) USB is not supported. It may work, or may not work.

    It must be something different trying to boot Windows from an external drive connected with USB. As I said in my previous post, I have before cloned Windows from one SSD disk to another SSD disk. However the old disk was switched out from my laptop and replaced with the new disk. Windows booted fine on the new internal disk, even though it booted from a different hard drive than before.

    When Grub2 list up both my Windows drives it seems to boot both up without problem (the internal and the external).
