    Default multi boot Win7 - Fedora - BT4

    Hi
    I have first installed Win 7 without problem, (/dev/sda1)
    After what, I install Fedora 12 (/dev/sda2 for /boot, /dev/sda3 for / and /dev/sda5 for the swap)
    And then I install BT4 (/dev/sda6 for the swap, /dev/sda7 for /boot and /dev/sda8 for /)

    After Fedora installation, I could go from one OS to another without problem.

    But After BT4 installation, I could only go from Win 7 to BT4 OS, but I can not go under Fedora.
    Is anyone familiar with grub?

    Here is /boot/grub/menu.lst file

    Code:
    # menu.lst - See: grub(8), info grub, update-grub(8)
    #            grub-install(8), grub-floppy(8),
    #            grub-md5-crypt, /usr/share/doc/grub
    #            and /usr/share/doc/grub-doc/.
    
    ## default num
    # Set the default entry to the entry number NUM. Numbering starts from 0, and
    # the entry number 0 is the default if the command is not used.
    #
    # You can specify 'saved' instead of a number. In this case, the default entry
    # is the entry saved with the command 'savedefault'.
    # WARNING: If you are using dmraid do not use 'savedefault' or your
    # array will desync and will not let you boot your system.
    default         0
    
    ## timeout sec
    # Set a timeout, in SEC seconds, before automatically booting the default entry
    # (normally the first entry defined).
    timeout         10

    Default Re: multi boot Win7 - Fedora - BT4

    So....
    what exactly happens when you are booting your System up?
    There should be a bootscreen where you can select your System, you want to boot from.
    Seeing your grub-List it should seem like this:

    Code:
    Ubuntu 8.10, kernel 2.6.30.9
    Ubuntu 8.10, kernel 2.6.30.9 (recovery mode)
    Ubuntu 8.10, kernel 2.6.30.9 (memtest 86+)
    
    Other OS:
    Windows Vista/Longhorn
    I saw some Code in your Grub-list that may be an error, leading to mistaken Boot-settings. I will mark it red here:

    Code:
    ## ## End Default Options ##

    try removing the red-marked part and boot up again. But backup this text-part somewhere, because i'm not 100% sure, if this is really the problem.

    Try and write back

    Best wishes

    Hi,

    You have two boot partition > dev2 and dev7.

    I think dev7 took over dev2 (boot partition for Fedora)..

    You need to had fedora to grub conf file

    --
    title Fedora
    root (hd0,3)
    # kernel /vmlinuz root=/dev/hda2 ro // not sure for this one
    --

    Try to find tutos on grub's configuration

    Well,

    Here is how I've done :
    I boot under BT4.
    With the fdisk (-l /dev/sda) and df (-a) command, I knew the différent partitions of Windows, BT and Fedora.
    I mount the fedora partition containing /boot
    I Open the boot file to copy all the lines between two line starting by Title.
    And then, I was able to connect to fedora.

    BUT I will have to change the BT4 boot file each time a new kernel will be installed on Fedora.

    Thanks to all.
