Computer Not Booting (An easy one for a change)

A customers computer would not boot. It came up with an error NTLDR not found press Ctrl-Alt-Del to reboot. The harddrive wasn't making a noise which was good for a change and could be seen in BIOS. I set up BIOS to boot from a BART partition on my thumb drive. Most BIOS have two boot places. One to pick the device type order and another for the Hard Disk device order. When I restarted the computer would not boot from my thumb drive.

I went into BIOS again and notice that the first device to boot was the USB HardDrive. I changed this to last position and then booted again and the computer booted beautifully.
