Windows 10: How to move Windows boot files to new drive?

I have an old PC which I have upgraded over the years.
It used to be a Vista / Win 7 PC which I then dual booted with Win 10 on a separate new HDD - and also Ubuntu on the Win 7 HDD - but the boot information has always remained on the original Win 7 HDD.
I recently fitted a SSD and cloned my Win 10 installation onto it. As I had a multiboot setup I simply added the new SSD as the default drive.
The problem came when I tried to remove the original Win 7 HDD. The PC simply stalled as it did not have any boot info.

How can I move / create reliable boot information on the new SSD?

I do not want to erase any of the existing HDDs - at least as yet.

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.

 

Windows 10 Tweaks

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK

Can't boot up win Windows 7! Halp!

I never got to any options or install screen or anything, it was just "loading windows files" and then the screen. I tried it 3 times, went through those steps all 3 times. I've only been booting from the disc, it's not installed to boot from the drive.
