Abit KT7A motherboard. Ubuntu 5.10. Windows 2000 was hda, Ubuntu was installed to hdb with no errors. On boot up, things hung at the infamous Error 21.

GRUB loading, please wait...
Error 21
</samp></pre>

After finding this and <a href="http://ubuntuforums.org/showpost.php?p=9327&postcount=6">other posts</a> I tried first switching the drive positions and re-installing. That allowed me to have GRUB and Ubuntu installed on hda and I could boot up into Ubuntu - but the Windows drive, hdb, still wouldn't boot from GRUB and still gave Error 21. If I understand correctly, the Master Boot Record on the Windows drive of mine was messed up. (I thought about trying something from the XP install/recovery CD with <code>fixmbr</code> or <code>fixboot</code>.)

Finally, on a hunch - somebody's comment someplace - I changed the second drive from <code>auto-detect</code> type to <code>manual</code> and <code>LBA</code> and then both operating systems could boot from GRUB without errors.
