Having issues getting a Dell SX260 to boot from USB key, used this FAQ:

http://www.knoppix.net/wiki/Bootable_USB_Key

A usb key created using a Dell D600 boots the D600, yet won't boot the SX260. A usb key created on the SX260 won't boot the SX260, haven't tried botting the D600 with it. SX260 sees the usb key on the F12 alternate-boot menu, yet won't get past "no boot sector found".

Ideas? Really want to get the SX260 usb key working, as cd-spinup on boot and operation is noisy, and the silent D600 shows how quiet the usb key is.

Thanks!
