Windows 7: Booting from another drive

Booting from another drive

Hope you guys can make a long story short. I had a failure to my system drive (was my fault). Anyhow the drive was still under warranty so I did an RMA with WD. While waiting for my replacement drive, I reinstalled Win7 to another HD and it is now my system drive. Now that my replacement drive have arrived, I image the other HD and restore to the replacement HD. My question is, how can I have it boot from the replacement HD?

What I did was mark the old HD as inactive and marked the replacement as active but when I boot up, it tells me it cannot find a boot device.

Any suggestions is appreciated.

Hello speederd, welcome to Seven Forums!

You will need to do a startup repair up to 3 separate times with system restarts between each repair to write new boot files to the new Windows on the new HDD; have a look at the tutorial at the link below for the relevant links and some info.
Be sure to post back with an update.

You need to unplug the HD you don't want any longer, then mark Win7 partition Active first before running Startup Repair x3: Partition - Mark as Active

Have you set the hard drive you want to boot to as the first hard drive in the bios?
Set the boot order E.g. floppy/dvd/hard drive then set which hard drive you want to boot to first.

like many said here:

1. Set the new HDD as the first boot device
2. Set the new HDD as active
3. Do the startup repair three times
