I have followed the instructions in unetbootin carefully but when i reboot i get error unknown file system

Asked by rottywas on 2011-03-04

I am trying to load fedora 14 86-x64 onto a partition on an external usb hard drive. My computer, an HP pavilion p6327uk running windows 7 x64, has no boot from usb option so I downloaded unetbootin and followed the instructions (on the wesite) very carefully. When I rebooted into the bios boot menu I saw no change except in the hdd group boot priority I have two drives, wdc wd15eads-65 (the internal drive) and wd ext hdd 1021 which is the usb drive but this drive is disabled and Idon,t know how to enable it. I then rebooted directly into the boot menu (esc) where I again found the two drives but when I selected wd ext hdd 1021 I got this error message; error: unknown file system grub rescue >- so I am now stumped. Can someone PLEASE HELP
thanks.

Is the partition on your external USB hard drive formatted as FAT32? If not, reformat it as FAT32 and try again.

ADDITIONAL QUESTION:
I have the same option. My HP Pavilion Q720 does have the USB Harddrive boot option, so that part seems to work.
However, it does boot from the USB, i do get the UNETBOOTIN screen.
But whatever option i choose afterwards i get: "root=live" and " Don't know how to handle this".
after that the system is halted and i can only reboot by removing the power AND the battery.

1. I did check the syslinux.cfg it seems to look OK. (the error message is not there, so it comes from someplace else).
2. the files that syslinux tries to access are in the proper place
3. The memorystick is set up as FAT32.

I think I checked the proper oparts (the fact that i get the boot option is proof that it is actually booting from the USB.
I am trying to use Fedora 14 (32 bit edition). I read that this solution cannot work with the 64 bit edition (backtrack forum, which pointed me to UNETBOOTIN to begin with.

What did i forget? (i reckon i must have forgotten something).

Can you help with this problem?
