    Linux installation on a 2d hard drive.


    Hello,

    I have installed Linux Fedora on my newly installed 2nd hard drive. My Primary C: hard drive has Windows Vista OS.
    I want to know how I can boot from the 2nd hard drive and use the Linux Fedora. Is it possible to make a floppy boot disk while installing that I could use at start up to run Linux? Or could I somehow have the option at startup to pick the Vista OS or LINUX OS?

    Thanks very much,

    Perry

    Here is the grub.conf file

    # grub.conf generated by anaconda
    #
    # Note that you do not have to rerun grub after making changes to this file
    # NOTICE: You have a /boot partition. This means that
    # all kernel and initrd paths are relative to /boot/, eg.
    # root (hd0,1)
    # kernel /vmlinuz-version ro root=/dev/VolGroup00/LogVol00
    # initrd /initrd-version.img
    #boot=/dev/sda
    default=0
    timeout=5
    splashimage=(hd0,1)/grub/splash.xpm.gz
    hiddenmenu
    title Fedora Core (2.6.18-1.2798.fc6)
    root (hd0,1)
    kernel /vmlinuz-2.6.18-1.2798.fc6 ro root=/dev/VolGroup00/LogVol00 rhgb quiet
    initrd /initrd-2.6.18-1.2798.fc6.img

    What is your current problem? Are you able to boot Linux but not able to boot Vista? Can you post the output of
    Code:
    su
    fdisk -l
    or
    Code:
    sudo fdisk -l
    the l is a small L

    Also do you know which disk BIOS tries to boot from first?

    Edit grub.conf file :
    Code:
    title Windows Vista
    rootnoverify (hd0,0)
    chainloader +1
    In case it doesn't work, post the output of fdisk -l command here.
    Code:
    su -
    fdisk -l
    It is amazing what you can accomplish if you do not care who gets the credit.

    After adding the above code the grub.conf it looks like this:
    grub.conf generated by anaconda
    #
    # Note that you do not have to rerun grub after making changes to this file
    # NOTICE: You have a /boot partition. This means that
    # all kernel and initrd paths are relative to /boot/, eg.
    # root (hd0,1)
    # kernel /vmlinuz-version ro root=/dev/VolGroup00/LogVol00
    # initrd /initrd-version.img
    #boot=/dev/sda
    default=0
    timeout=5
    splashimage=(hd0,1)/grub/splash.xpm.gz
    hiddenmenu
    title Fedora Core (2.6.18-1.2798.fc6)
    root (hd0,1)
    kernel /vmlinuz-2.6.18-1.2798.fc6 ro root=/dev/VolGroup00/LogVol00 rhgb quiet
    initrd /initrd-2.6.18-1.2798.fc6.img

    title Windows Vista
    rootnoverify (hd0,0)
    chainloader +1

    The error I now get when I try to boot windows Vista is now different, it is now:

    Bootmgr is missing

    Thanks

    Looking at your fdisk- is sdb3 your Vista ?
    Try changing the bios boot order, will Vista boot ?

    rootnoverify (hd1,0) ==sdb1 recovery partition
    rootnoverify (hd1,1) ==sdb2 could be the Vista OS partition
    rootnoverify (hd1,2) ==sdb3 likely the Vista OS partition

    (hd0,0) ==sda1 is listed as a NTFS partition on your linux hdd, suspect it is a storage partition ?? Not your Vista OS partition.

    Grub error 21 is "Unknown boot failure"
    Grub error 2 is "Selected disk doesn't exist"
    as stated at GRUB Error Messages
