Bootable USB key

Posted on 10 May 2010 22:14 | 1 comment

Ubuntu 10.04 has some issues with unetbootin, so if you like to boot ubuntu 10.04 using a usb do the following:

- format the usb as FAT32
- mount the usb disk (/dev/sdX) as /media/aaa

X is assigned by the system. Most of the time it’s /dev/sdb1 or /dev/sdc1. If you want to know type: df -h

- After mounting type:

grub-install --recheck --root-directory=/media/aaa /dev/sdX

Don’t use any numbers at the end. So /dev/sdb or /dev/sdc

- Copy everything from the iso except the directory /boot.
- Copy the /boot/grub/grub.cfg from the iso to the /boot/grub directory on the flash

Now you should be able to use your usb key with grub2 and ubuntu 10.04!
