Hi.
I recently installed Ubuntu 10.04 on my laptop with an USB-drive. The problem is, like the title says, that it doesn't boot unless the USB is plugged in. I've searched on internet and found one solution


sudo fdisk -l
# identify your hard drive e.g. /dev/sda
sudo grub-install /dev/sda


But it doesn't work.

Thanks

sudo grub-install /dev/sda

must be followed by

sudo update-grub

sudo grub-install /dev/sda

must be followed by

sudo update-grub

It doesn't even find /dev/sda without the USB plugged in. Only

with your usb drive plugged in, open a terminal and enter df -h and please post the results.

If the drive is sdb then the correct place to install the grub2 boot loader is the MBR of the sdb drive.

When you did the listing from fdisk it said sdb not sda so you are supposed to change to that drive.

sudo grub-install /dev/sdb
sudo update-grub

You know, slightly off-topic but this could be a neat security feature for some. While not a total show-stopper it would slow folks down who didn't know you needed the thumb drive in. :P
