Live USB-stick format

08-03-2008, 03:57 PM

I want F9 on a USB stick. It's 8GB, and comes with a few files concerned with
using it on windows, so I don't really care whether they survive or not.

Most of my hardware is not so young, and doesn't boot off usb sticks.
However, the EeePC should do - it does from a Mandriva flash drive. It lists
the drive, in BIOS, enclosed in [ ] which seems to mean that it is not
bootable, so I looked at the drive with fdisk. It says

Disk /dev/sdc1: 8120MB
Sector size (logical/physical): 512B/512B
Partition Table: loop

and that 'The flag 'boot' is not available for loop disk labels'

Obviously I've done something wrong, but what?

Best guess is that you formatted it without a partition table and/or
boot sector. Try "fdisk -l" as root and see if you get more information.

Dumb question - did you run "fdisk -l /dev/sdc" or
"fdisk -l /dev/sdc1"? The first form is the correct one, and the
second one will give strange results. From the output it looks like
you used the second form.

Mounting the drive from a running system, I can see all the directories that I
would expect to see.

Mikkel, I'm away from home and from the laptop I used to do the install, so I
can't examine the history to find out.

Mounting the drive in a running system shows all the expected directories
under /media/Z Mate 8GB/DaneElec, and as you will see in my reply to Bill,
fdisk shows

/dev/sdc1 * 1 1023 8055071 83 Linux

OK - you have the boot flag. The problem may by that there isn't a
boot loader in the MBR. It depends on how the stick was formatted
from the factory. You may need to install makebootfat to make the
stick bootable. I think there is also a way to do it with syslinux,
but I am not sure.

makebootfat?? It's a Linux partition, hopefully one could boot a rescue
disk, chroot to the stick, and grub install on the device. I'n assuming
that Anne checked for the presence of the /boot partition on the USB, etc.

You are correct - not one of my better days.
