Question attempting to install mythbuntu..Grub error 22 / can't reboot from XP cd .. help!

Hello from St. Catharines Ontario..

I recently installed mythbuntu on my pc and after finishing the installation / rebooting the computer I got the infamous Grub error 22.. I have no idea what to do after this. I have exhausted the forums and found the most common solution is to set BIOS to boot CD (primary), HD (secondary), and then reboot into the recovery console using the XP cd.

I have tried this but for some reason it will not boot directly from the CD. I tried to set BIOS to only booting from CD (by removing the HD as secondary) but when I do this I get the error "disk boot failure, insert system disk and press enter" - when I insert disk i hear the disk spinning but pressing enter does nothing.

A little background... The day before installing mythbuntu, I had reinstalled Windows XP64 as the sole OS on my computer using the XP64 cd (so i know it works). I burned the mythbuntu iso onto a disk and then installed it using the first option for the partition stage of the installation (divided partition) alloting half my disk space to mythbuntu (around 130gb)

So now when I start the computer, if I leave it to boot up freely, I get the Grub 22 error and then have to shut it off. If I try to start it with the XP CD in the drive, it does the exact same thing without giving me the option to go into recovery mode.

Can anyone help me with this??? Thanks in advance!

Have you tried booting another comp with that disk? Either the disk isn't bootable or cdrom drive is not booting up first. Check that the disk is bootable and read your motherboard manual to make sure your settings are correct. My bios has two separate options for defining boot order.

Here is the grub site for errors and other helpful grub information; , you may want to boot to a partition tool CD to view all the partitions, such as this one here;, and after booted either to a live Linux CD or USB flash drive, you run this; fdisk -l, as the root user, which shows all drives partitions, and you can copy and paste it as a text file to save and print it. Also real handy to boot to is this disk; You then may need to edit your grub boot menu file here; /boot/grub/menu.lst so that it boots to the correct one for your Linux. Are you dual booting with windows XP ?
