So I had a 1TB drive with 2 partitions - Windows 7 64bit on C: and Data partition on the rest (F
Bought a Samsung SSD 830 256GB
I used Norton Ghost 15 (actually followed Samsung's Data Migration manual that came with the drive) to clone the old OS drive to the SSD. After the clone, I shut down the system, unplugged the old drive, booted the system. Boots fine until it gets to the Windows login screen, sits there for maybe 10 seconds, i'm lucky if I can get my password typed in, then it just reboots. If I plug the old drive back in (so both drives are plugged in), it will boot without issue. After doing so and logging in, Windows is definitely running off the SSD, and the SSD is assigned drive letter C: and marked the boot partition. The old OS partition is drive G:. I tried running startup repair with only the new SSD connected, and it didn't even list any drives. Not sure if I need drivers, it's connected to the Intel SATA3 controller on an Asus P8P67. Ran it anyways and it didn't do anything, as expected.
Obviously, I can't boot from just the old drive, as it complains of missing media.
Ran EasyBCD and it seems like everything is pointing to C: in the MBR. That's about as deep as I've gotten, and I don't have much experience beyond that.
Can anyone give me any ideas as to what's going on here?
So basically, Windows won't boot unless both drives are connected.
