Title:
Grub2: Unexpected floppy access during boot
Status in grub2 package in Ubuntu:
Incomplete
Bug description:
Binary package hint: grub2
Observation:
During the startup Grub2 always accesses my floppy drive. This happens right after the start-message of grub, but before the appearance of the menu.
Directly after the very noisy floppy-access an error-message is shown wich says something like "bootdisk error". But this message appears only for a fraction of a second and is therefore difficult to read. Instantly after this message has vanished, the normal boot-menu shows up.
The boot process itself is not harmed, though.
My System:
I run a Karmic which has been upgraded from Jaunty. After the
additional upgrade from Grub-legacy to Grub2 the problem occured.
"/boot" and "/" are on separate md-RAID1 devices. In the BIOS-Setup
boot from floppy is disabled.
