Hi everyone, please help!

I put 9.04 on a 4G USB drive by removing the HDD from my laptop and installing from the live CD, using the entire stick during the partitioning phase. But GRUB doesn't see the stick at the boot: prompt.

I tried root (hd0,0) and (hd0,1) but it always returns Error 21 Selected disk does not exist. fdisk returns (hd0,0).

I did read that some sticks refuse to work. Is this my problem? Are there any workarounds? Should I post any other information? Thanks in advance!
