Windows won't boot with new SATA drive installed

[mephisto1296]

So i had a western digital external hard drive which i was having problems with. when i took it apart and realized that i could make it an internal hard drive i immediately mounted it and plugged it into my mobo. It appears in my Bios but windows 7 will not boot while it is plugged in. I have tried changing the SATA ports around to ensure that my SSD is the primary boot drive, and i have tried booting from the windows 7 disc but windows will not boot while the hard drive is plugged in.

Leave the drive powered up, but remove the sata cable from the motherboard. Boot into Windows, plug in the drive.

If it's recognised, copy off the data whilst you can... after you have a safe copy you can try to get it working during boot. I'd say have a look at the settings for the sata ports (usually RAID/IDE/AHCI), change to IDE and try booting then.
