Trouble with startup usb creator

[dustyg54]

I am trying to use the usb startup creator to make a xubuntu 10.10 ( with downloaded .iso) startup disk to a 2gb flash drive. I formatted the drive to ext4, and when I start the usb creator I get this error: "Failed to install the bootloader."

1. Should I have formatted the drive to ext4? In the usb creator instructions the author used ext3 as an example.
2. I am using the 64bit .iso file. I am trying to make the drive from a 64bit pc running ubuntu 10.04 (64bit).
3. If I can get this to work, will the 64bit flash drive then boot using a 32bit pc? (I wouldn't want to install it, but rather boot to use as a portable OS.)

Thanks,
Dusty

Startup Disk Creator requires a flash drive formatted in FAT, FAT32 seems to work best for me.
32 bit is probably best for booting multiple computers.

That worked! Posting from the flash drive now. Thanks!

This solved for me as well. Seems prudent to either:
a) format the disk, since all data is lost anyway;
b) show an error message informing that the disk should be FAT32...

It need FAT because the isolinux needs it i think.:P too bad it doesnt support ext4 :(
