Re: Grub2 on USB-Stick fails install

[David Balažic]

You could try to repartition it, using fdisk:

(unmount the USB stick first)
sudo fdisk /dev/sdX

 - create a new partition table (not sure which command, enter "m" for 
help)- I think it is "o"
 - create new partition : n
 - select type "primary" : p
 - select number 1 : 1
 - select default begin: just press enter
 - select deafult end: just press enter
 - write new partition table and exit: w

(just in case unplug and replug the USB stick, so the kernel uses the 
new partition layout)

Then format the partition: sudo mkdosfs /dev/sdX1

Then you can follow the instruction from 
http://www.pendrivelinux.com/install-grub2-on-usb-from-ubuntu-linux/
from the point 5 on.

Hope this helps.
