creating a bootable USB drive - Grub

Hi all,

I am trying to create a bootable usb drive with any linux OS preferably fedora and maybe a backtrack manually and not with 3rd party software but I am having difficulty.

I have a 4gig usb drive.

I laid down a ext3 partition
~ mke2fs --> which was successful
~ I also copied my boot directory from a previous fedora install

Now on my usb drive I have a boot dir and w/in that boot directory I have all the grub stuff.

When I boot to the usb drive only a grub command line show and I can't do anything on it.

In my grub directory I do have an Image and initrd file.

Any help for a simple process would be much appreciated as I have been reading grub material all week and still not getting too far.

Thank you!

Did you install Fedora to the usb?
If so, how?
What operating system is installed on the computer?

That won't make it bootable. If you could answer the above questions and with your usb drive attached run the command:

fdisk -l(lower case letter L in the command)

post the output here and post the contents of the /boot/grub/grub.conf file on your flash drive.

Image?? You mean the fedora iso image?

I do not have an .iso copy on the usb drive. I suppose one should be included within the drive?? -> Is this correct?

Please let me know ifmore info is needed.

Below is my single partition on the usb drive

Disk /dev/sdb: 4012 MB, 4012900352 bytes
59 heads, 28 sectors/track, 4744 cylinders
Units = cylinders of 1652 * 512 = 845824 bytes

Device Boot Start End Blocks Id System
/dev/sdb1 2 4745 3917824 83 Linux

Below is the contents of the Boot directory -> the only directory on the usb drive
