Windows 10: Replaced hard drive, installed windows, went OK. Reverted to old drive, won't boot.

I have a windows 8 computer. I removed the hard drive from the computer and replaced it with a new one. I installed windows 10 on it and it works. When I remove the new drive and replace the old one, I cannot boot to it. It shows a black screen with an underscore. When both drives are installed it will boot to the new windows 10 and I can see the old drive and its files. I ultimately want to be able to select which drive to boot to on startup. Thanks for the help.

Replacing old hard drive, need way to copy Windows installation across

Hey Guys,
What would be the best way of copying/imaging the entire contents of an old system drive over to a replacement hard disk for the same machine? I need to copy the Windows installations and all other data to the new drive, and then format the old drive to use as a backup.

Any suggestions? *Smile

 

Need help installing a new hard drive

Basically what I'm saying is I want to install windows onto my new hard drive and boot from it
But for windows 7 to recognize that it's a two drive system, as opposed to just replacing the old hard drive entirely with a new one

 

Windows 7 booting off wrong drive?!?!?

Please move if this is in the wrong place.

I have two hard drives, a 1.5TB drive, and a 160GB drive. Windows is installed on the 1.5TB drive, as are all my files and programs. The 160GB drive has a bunch of old files, and apparently the bootmgr and boot folder. Nothing else is on the 160GB drive, other than media files etc.

If I remove the 160GB drive from the machine, windows refuses to boot, plug it back in, it works fine. The setup with two hard drives I have now is temporary, as the 160GB drive will go into another machine.

My question is, can someone give me a step by step on how to make windows force to boot off the 1.5TB drive, ignoring the 160GB drive in the boot process completely?
I don't know how to do this in Windows 7, on XP I would just run the /fixmbr command and its related ones.

Any help would be appreciated.

Note: I would really really rather not have to wipe and reinstall, I know it can be done without one as I've had this issue with XP before.
