Interesting issue, didn't cause me any harm, but only by chance. I was installing Ubuntu 9.04 64bit server from the CD on a machine that I normally run ESXi on. I wanted to test disk speed on a direct install vs. the install in ESXi, so I installed a 4th hard disk, shutdown ESXi, and installed Ubuntu directly on the new disk (4th Bios disk - SCSI:3 or sdd). When I tried to boot from this disk, nothing happened. I rebooted from the ESXi install disk (SCSI:2 or sdc), all was fine. Playing around, I finally found that to boot the ubuntu install, i had to boot from SCSI:0 - Grub had installed there, even though I never indicated that disk for anything during the install. It would be much better if Grub ASKED where it should be install, rather than assuming.

Did you use the Desktop CD to install Ubuntu?

Yeah it is the default. I think you have to choose expert mode when booting the server CD to choose the Grub install location. I believe there is a warning, but again not sure unless you choose expert install.

Just as you finalize the partitioning during the install is an advanced button. That lets you choose which drive to install grub.
