Thread: Fresh Windows 8 dual boot. Using GRUB2 causes Windows update failure?

    Default Fresh Windows 8 dual boot. Using GRUB2 causes Windows update failure?

    Hello everyone!

    A few days ago I decided to reformat my desktop PC for various reasons, and set up a Windows 8 and Opensuse 13.1 dual boot. When I had this setup before, I used Easy BCD to allow the windows boot loader to load Opensuse. I didn't like the way that setup worked, so I wanted to do it the better way this time and use Grub2 as the boot loader, which seemed to work fine. I could dual boot into both systems.

    However, there were security updates in Windows 8 that I just could not get to install no matter what I tried. I was also unable to update it to Windows 8.1 through the store.

    Finally I reinstalled the Windows boot loader, and the updates were able to install. I had to go out of town now and am away from my desktop, so I didn't get a chance to try the Windows 8.1 upgrade yet, but I suspect it should work fine as well.

    As much as I'd love to ditch Windows completely, I can't. At least not yet.

    Searching the internet just leads me to a lot of threads about people who can't get the dual boot part working, which for me wasn't a problem. My machine is a bit older.

    So, has anyone else encountered this problem and found a way to fix it? I set my boot loader to load from MBR, but should I have set it up differently?

    Here's a bit of info that I can remember.

    Motherboard is a Gigabyte GA-970A-D3. I had installed Windows 8 first as a primary partition. Then I used GParted to shrink the partition down, created an extended partition for Opensuse 13.1, and installed it with the boot loader set to boot from the MBR. I had also installed a 512mb boot partition.

    I really hope there's a way to use GRUB2 as my boot loader and have both systems work smoothly.

    Thank you for anything!

    When Windows is installing updates that affect its booting, it tries to check out everything. And if you are setup for grub2 to handle the booting, it won't check out and Windows will back out that update.

    My solution was to use the Windows boot manager to boot linux -- about what you were doing with EasyBCD. But I could then set the active partition to the linux partition and I would boot with grub2 alone. If I am having problems with a Windows update, I set the active partition back to Windows, and install the update. I can revert to boot with grub2 at a later time.

    Hello!

    That sounds like a good idea. So you install Grub to a /boot partition, and just set that partition as active with diskpart in Windows?

    Thanks!

    Right.

    I have Windows 7, and openSUSE. I take care that the master boot record
    (MBR) is the original of the machine, never grub. The extended partition
    is marked as bootable, grub is there, and /boot is a logical partition.

    If Windows complain, I set back the first windows partition as bootable;
    I do the updates, and then undo the marking with any Linux rescue cd.

    Alternatively, I could use EasyBCD, but last I heard is that it did not
    work with Windows 8.

    As far as I know, it works with MBR systems, but not on UEFI systems.

    Hello again,

    This is how I'll set it up when I get back home. I didn't want to use EasyBCD again, and Grub2 boots the machine much faster than the way EasyBCD had set it up.

    And yes, EasyBCD worked well for my non-UEFI system, aside from it having to reboot when I picked a system other than Windows.

    Thank you very much!

    I don't remember that.

    I got a very simple, ugly, text menu at boot, where I could choose which
    system to boot.

    This unfortunately has high chances to break when grub2 is updated. My be allowing to specify boot sector device and device to embed core.img separately could be a solution ....

    Note I could be wrong with Win8. In most cases Windows only check the boot flag (except for ver upgrades) so If you put grub in MBR and set the boot flag to Windows most updates should work.

    I refuse to dance to MS's tune so I only run Windows from a VM This works great as long as you don't want high end MS games.

    The reason I use Windows some times is to maintain and upgrade certain
    gadgets, like cell phone, car navigation system... Well, one of these
    gadgets refused to connect to Windows on a virtual machine, it had to be
    a real one.

    It is funny that several of these gadgets are Linux inside, yet they
    only work with Windows proprietary software for management.
