    Booting CentOS 5.2

    i am getting a boot error after a fresh install.

    Error 21: Selected Disk does not exist

    press any key to continue

    after i press any key it get to GRUB

    what i have in the computer is
    1 250 GIG IDE HD (i want to install and boot from this drive)
    3 500 GIG SATA Drives that are hooked to a PCIE raid card

    i can see all the drives when i install and when i install i select that i want to use my IDE drive for the installation.

    it installs and then when i reboot i get the error 21.

    should i unhook the raid, install on the IDE get a successful boot and then install the raid?

    any help would be great

    thanks

    i was able to get it to boot once i was in GRUB

    my setting was set to hdd(3,0)
    i changed it to hdd(0,0) and it booted

    then udev failed
    so i let it keep going

    it has been booting for about 20 minutes now

    everything says OK but it is taking forever

    One hour later it still has not booted

    HAL failed and now it is just a blue screen with the mouse pointer that does not move when i move the mouse.

    it went through the boot up and at the end HAL failed and went to what i thought was going to be the login screen but it is just a blue screen.

    i went through the initial setup and then it wanted to reboot

    udev failed again and it seemed like it was going to take another hour to boot up so i quit and i am installing fedora 9.

    yes, this should eliminate the grub problem on boot, as for the slowness problem, it could be related to the raid hardware, at least try doing an install with it unhooked and see how it goes

    installing without the raid card hooked did solve the GRUB problem

    udev failed again. and is taking forever to boot

    udev works just fine in fedora

    i am thinking about just using fedora 9 and be done with this

    maybe there is a udev package update that will fix the problem after it boots
