Hi I'm a fresh ubuntu user but i encountered some problems with the instalation.

It seems that the ubuntu was installed succesfully but when i tried to start it without the cd i got

error 21

It is installed on an external disk and on my internal- i have windows xp ,wich would also not start now.
I tried already typing sudo grub-install /dev/sdb at the command but i get answear:

could not find device for /boot: not found or not a block device

Windows would not start also with or without the usb disk
Can anyone help me ?
Thanks!
