    Angry No Boot Loader on Startup - Dual OS (XP and Ubuntu)

    Hi. I have practically raided the forums for answers but I cant find anything that works.

    I have XP installed on my pc, and decided to have dual OS with Ubuntu.. So i already installed Ubuntu on this one partition, and everything was installed.

    During reboot, no boot loader showed up. It automatically boots XP.. I dont have any idea how to access my already installed Ubuntu. Im thinking it's really installed since the partition cant already be found in XP.

    can you help me? i want Ubuntu on my pc!! NOWW!

    thanks.

    Boot from the live CD and type in the terminal
    Code:
    sudo fdisk -l
    where -l is a small L and post the results

    OK , your partition table shows that you have the two necessary partitions for Ubuntu. now type in the terminal
    Code:
    gksudo gedit /boot/grub/menu.lst
    and post the results to see the operating systems already on your machine.

    The bios will always look for a boot sector on sda first and if it finds one it will use it. That is what is happening to you. Grub is on sdb and the xp boot loader is on sda so it goes first. You can also install grub on sda if the following is beyond you but this only takes a few minutes.

    Try swapping the plugs on the drives and make your Ubuntu drive sda instead of sdb.

    It is not difficult to do, all you need is maybe a screwdriver, maybe not even that.

    If they are SATA drives, the ones with the little cables instead of the big ribbon, just swap which plug they are in on the motherboard. If you have only one drive it does not matter which plug it is in but when you start adding drives it does. Lazy assemblers will just plug a single drive into any SATA port on the motherboard. It is a common thing.

    If it is the ribbon cable type (PATA) you will need to change the little jumper on the back of the drive to make the Ubuntu one the master and the windoze one the slave There is a little sticker on the top of the drive to show you what you need to do. You might also need to change them so your Ubuntu drive is the first one on the cable.

    This way is also better because if you need to remove or replace either drive the other one will boot.

    Hope this helps.

    You can also boot Ubuntu with Super Grub:

    Had the same exact problem on my laptop, all I did was clear the CMOS since it seemed to be a BIOS error
