    Default Dual Booting Windows 7

    I am going to be replacing the Vista installation on my desktop with Windows 7 (a disk/key came with my new computer and I won't be using it there). I already have openSUSE, Fedora (PlanetCCRMA) and Archlinux installed on this machine, and I have Grub set up to multiboot all these (and Vista). Obviously, after installing Win7, I won't be able to get to Grub, or any of my other OSs. So what steps should I take to get Grub back and get my Win7 install added to it? Are there any tricks I should know?

    Thanks.

    So I assume you are using the grub menu you currently want to use and you know where that menu.lst is ?

    Can you post your current fdisk -l
    and explain it?

    First two partitions are utility/recovery. sda3 is the Vista install. Following that is an extended partition (sda4) with my Arch /boot (sda5), Fedora (sda6), openSUSE (sda7), openSUSE /tmp (sda8), Arch / (sda9), swap (sda10) and two data partitions mounted under /home (sda11 and sda12).

    I will be resizing/deleting the last two and creating an additional NTFS partition for the Windows 7 install (for data, not OS). I'd like to install Win7 on the Vista partition (sda3).

    The boot menu is openSUSE's, on sda7; I believe I installed it to the MBR.

    By the looks of that the bootloader is not to the MBR
    See the boot flag on the extended partition!

    When you install W7 that flag will be moved to sda3

    If you have the SUSE DVD, you can use that to fix grub. Or I have other ways, if you can't get that to work

    I noticed that too. What confused me is that I am certain I selected "Install to MBR" during installation. But whatever works, I guess.

    I've used the openSUSE installation disk before to set up Grub after installing another OS. I wasn't sure if Windows 7 had any specific issues in that regard. I guess not?

    Thanks for the advice.

    All I would say is there were issues with grub on the MBR when Vista wanted to install service packs. My guess is W7 will be the same. Users with grub on the MBR had to restore windows bootloader, install the service pack, then re-install grub. The grub bit takes a few minutes, but expect the service pack to take it's sweet time.

    With windows 7, do you have an actual install DVD? It kinda sounds like you do. Just stick it in and boot from it


    1. Choose your language settings, and then click Next.
    2. If you are using the Windows installation disc, click Repair your computer.
    3. Select the Windows installation you want to repair, and then click Next.
    4. On the System Recovery Options menu, click a tool to open it.



    Automatic repair should do it and not touch your Linux installs

    I do have an install DVD. That sounds just like what I needed. When I install Win7, I'll probably try to get it all updated before I reinstall Grub; I'll be sure to keep both install discs on hand, though!

    Thanks so much for the assistance.
