I downloaded the CD ISO of BT3 and had no problems with this, thought it was great and now want to get BT3 booting from USB. I have now downloaded bt3final_usb.iso and I followed the guide on the Wiki of how to make a bootable USB drive.

When I try and boot from this I get the boot menu, select an option and then during the load i get the following error -

* looking for data directory
Fatal error occured - BT3 data not found.
You are maybe using an unsupported boot device (eg. SCSI or old PCMCIA).
Workaround: Copy the directory BT3 from your boot device to an IDE/SATA disk, eg. to /mht.hda1/BT3 or C:\BT3. Then try to boot again.
* Something went wrong and we can't continue. This should never happen.
* Please reboot your computer with Ctrl+Alt+Delete ...

Obviously as I want to boot from the USB pen-drive then copying the BT3 directory to an IDE/SATA disk defeats the object! I have got the BT3 directory on the root of the drive but don't really understand why I am getting this error.

Any ideas guys?
