Yes with the old drive it would boot from A:, D: and, of course, C:.
Now it just goes to a setup type screen that lists the harware eg. CPU, RAM, HARD DISK 0, etc. This screen lists the Hard drive as 8455 Mb rather than 12.07 gigs. Then i just get a blinking cursor that will not move. Can't even ALT+Ctrl+del to reboot. The HD light is on steady as well.
