Thread: How to make SUSE boot independent of Windows?

  1. #1

    Default How to make SUSE boot independent of Windows?

    I'm a new SUSE user. I have some rudimentary understanding of unix. IOW, please elaborate

    I've read many, many posts about boot conflicts with Windows. I have an idea but I don't know whether it is possible or how to do it. I have read the GRUB manual and am still at a loss.

    I have Vista on hd0. I have SUSE on hd1. I would like independent booting so that if I ever reinstall or upgrade Vista I don't have to use a grubby recovery disk to reinstate SUSE.

    Is it possible to either:
    a) Make the SUSE hd1 boot on its own? (I can select to boot from this drive in the bios menu)
    b) Set up a CDROM or USB memory stick to act as a booter for SUSE on hd1?

    If so, how?

    Thx
    Brian

    1)Yes install grub to the same drive as Suse i.e hd1 it will default to the primary boot device(hd0) iirc so will take some user intervention when the grub install is presented. Just make sure you're choosing to install to the mbr of the second drive

    2)Yes both the netinstall iso does this anyway top choice is boot from harddrive. As for USB you can install grub to USB quick google Rene Mayrhofer - Making a USB Stick bootable with Grub (not a recommendation barely looked at it just an example) plenty of tuts about this.

    3) you can also chain load Windows I believe to do this. Think this tut works Boot Multiboot openSUSE Windows (2000, XP, Vista - any mix) with Windows bootloader.
    Man first, have a try at Info, have a look at Wiki, if all that fails Scroogle!!!!!

    If you make sure the grub bootloader is on hd1, what's the problem. SUSE IS booting independent of windows.

    Thanks for the help.
    It is reassuring to know that the two disks can be separately booted with the right set up. I'm not sure why this wasn't mentioned as a way to avoid Windows sabotage in any of the articles I read.

    I did try the Rene Mayrhofer method yesterday but couldn't get it to work. When I booted from the USB stick I only got a black screen and a flashing cursor. I may have done something wrong.

    In the GNU GRUB manual it says to do something like:
    grub> root (hd1,0)
    grub> setup (hd1)

    Is this all I have to do to boot SUSE off the hd1 drive? Or is there more to it (I expect so)?

    It's as simple as installing grub to hd1

    If you have 2 HD's with windows on one and SUSE on the other, it's a great setup. The win hd doesn't need to be touched. BUT it will be changed in boot priority in BIOS. We will need SUSE hd first! So although we say SUSE is on hd1 it will become hd0 in BIOS. How it is seen in SUSE will depend on your initial install setup of the HD's
    Ideally with win installed on hd0, then switch hd order to have Linux hd first, now install SUSE.
    So long as you can identify the HD's during install you can get grub installed correctly.

    You can always remove the power from the win HD if unsure, install SUSE, then manually add all the necessary details for the win hd once pluged back in.

    Are you trying to do this after the fact if so then try using yast boot loader as for your example yes it looks sort of correct but I tend to use yast. Sometimes the cli grub isn't quite as smooth as you can wish for I had it refusing to recreate menu.lst the other day.

    Though doing it this way will mean going into bios tbh I'm not surprised most people don't want to have to go into bios to choose an OS. Though I can see why you wish to but personally and for many others re-installing any distro isn't a common occurrence and the fix is minor and relatively easy.

    If you have installed your two operated system in diferent hard drive you only need to change the boot drive in the bios.

    Remember the boot loder of Linux has to installed in hard drive.

    well, it will only stay that way until the first time you have to fix
    the Redmond side by reinstalling...

    then, MS *will* overwrite grub and you will only be able to boot
    Windows...until you undo Bill's rudeness..

    Only if grub is on the same HD as M$. But in this discussion it's Not!

    ok...sorry...i missed that fact..

    but then i have to ask: if it _is_ possible to give a new guy who
    wants to dual boot, a surefire way to NOT have his dual boot
    capability murdered by Redmond Killers the first time s/he has to do
    the Redmond Cure-All (reinstall) then: Why the heck is that not the
    default way suggested by the install script (when two hard drives are
    available)??
