Comment 24 for bug 414996

Also affected: HP Proliant DL140, which has two Bays for SATA drives connected to a LSI Logic Raid Controller.

10.04 64bit Server Beta1, Beta2 and Release Candidate all behave the same when trying to install from USB stick.
Last binary I tried, downloaded a few hours ago: http://releases.ubuntu.com/releases/10.04/ubuntu-10.04-rc-server-amd64.iso

The installer environment detects the USB-Stick as /dev/sda and the only Hard Disk as /dev/sdb.
It displays the following for a second: Running "grub-install /dev/sda"

/dev/sda - the USB stick which contained ubuntu-10.04-rc-server-amd64.iso until now - now has the MBR needed to boot the proliant machine. The MBR on the hard disk drive /dev/sdb is not written.

On reboot with the USB stick disconnected, the screen justs blanks and displays a blinking underscore cursor.
(Without USB stick, the hard drive is detected as /dev/sda)

The USB stick can be used to boot the machine, log in and run "grub-install /dev/sdb", which fixes the problem.

Kind regards,
Flummy
