I have Kubuntu 8.04 installed on a zareason.com (Asus Bare bones) laptop.
Grub version is 0.97-29ubuntu21.1
I have only kubuntu installed on a single HDD
Today I turned on my laptop and grub? did not start. It was as if I had
no hard drive connected. The screen showed the little "Asus" logo in the
bottom right corner but this usually disappears within a couple of
seconds, this time it remained and nothing else happened. I ejected the
DVD that was in the drive (Batman: The Dark Knight; Special Features)
and rebooted (had to turn off my laptop manually by holding down the
power button as ctrl-alt-del did not work.) Same Thing happened.
I inserted a Live CD and could hear it spinning up to speed, but nothing
else happened. I rebooted again, but the live CD did not boot either.
It occurred to me that I had two external USB drives connected, neither of them
bootable.
I disconnected them and restarted again. My computer booted!
Without the USB drives my computer boots normally either from the HDD or
the live CD. The weird thing is that if only one of the USB drives are
connected my laptop will boot fine, but if both are connected it will
not. This was repeatable.
**Additional Details:**
My USB drives are an "iAudio G3" 2GB mp3 player and an "ExcelStore GStor Wave"
160GB Portabe HDD Serial/Number: BF16LH*********
My laptop has a total of four USB ports all of which were full when it would
not boot.
1 & 2 were occupied by the ExcelStore HDD which requires two USB drives (one
for additional power)
3 had the iAudio plugged into it
and 4 had the Mouse.
I have not tested tested whether removing the mouse makes any difference.
I have Kubuntu installed on a single HDD with the following partitions:
Number Start End Size Type File system Flags
1 32.3kB 255MB 255MB primary ext3 boot
2 255MB 8258MB 8003MB primary linux-swap
