Package: grub-pc
Version: 1.98~20100128-1.2
Severity: normal
I am seeing the same problem: grub reports this on startup and then gets no
further:
error: fd0 cannot get C/H/S values.
entering rescue mode
My system has three RAID1 md partitions across sda and sdb, containing swap, /
and /boot and it has another disk (sdc). With these plugged in, it all works
fine, but once I plug a USB drive in as well, the system won't start. I can
get it to start by removing the USB drive and resetting it (ctrl-alt-del or
power-cycle). This is not ideal though, as it's a hidden-away server which
always has a USB disk plugged into it for backup purposes, so I cannot reboot
it remotely because it won't start up again.
