Thread: Add Windows to Grub

    Default Add Windows to Grub

    Hi,
    I have a dual boot configuration on my pc, with Windows Vista 64 bit and OpenSuse 11.1.
    After installing a new hard drive, I used Paragon Backup to restore my system. When the restore was complete, I got a message that my Linux Boot Manager needed to be restored, and when I re-booted, I got a grub error 17.
    I then inserted the Suse CD and did a restore. This appeared to correct the problem, but when I re-booted, I noticed that the grub menu list did not contain an entry for Windows.
    When I edited /boot/grub/menu.lst, I saw --

    I think, at this point, that all I need to do is add Windows to menu.lst, but I'm not having much luck doing it.
    Fdisk -l shows --

    This tells me, I think, that my Windows operating system is in the second partition of hd0.

    I found a sample entry --

    title WIN XP/Vista/7
    map (hd0) (hd1)
    map (hd1) (hd0)
    rootnoverify (hd1,0)
    chainloader (hd1,0)+1

    To begin with, I'm confused about whether I need the map statements since my OS is not in the first partition.
    And, if I code

    rootnoverify (hd0,1)
    chainloaded (hd0,0)+1

    the entry for Windows appears on the menu, but if I select it, I get a message that says that the Boot Manager is missing.

    Any help would be greatly appreciated,
    Thanks,

    If that's not working you may need to fix the windows boot sector code

    I will still try this though first

    Thanks for the reply.
    Before I fix the windows boot sector code, I'd like to verify that my entry is coded correctly.

    Just try different entries until you find the right one. It's not going to break anything. (well if you boot into a Windows recovery system, do not repair anything!).

    Code:
    ###Don't change this comment - YaST2 identifier: Original name: windows###
    title Windows1
    rootnoverify (hd0,0)
    chainloader +1 
    
    ###Don't change this comment - YaST2 identifier: Original name: windows###
    title Windows2
    rootnoverify (hd0,1)
    chainloader +1 
    
    ###Don't change this comment - YaST2 identifier: Original name: windows###
    title Windows3
    rootnoverify (hd1,0)
    chainloader +1
    If none of these works, try to add the map command.
    Code:
    map (hd0) (hd1)
    map (hd1) (hd0)

    Again, thanks for the replies.
    It turns out that I was misled by the sample code that I stumbled on. Instead of coding "chainloader (hd1,0)+1", I needed to code "chainloader +1". Once I corrected the error, the menu entry brought me into Windows.
