Windows 10: Second hard drive in windows 7 stealing the boot sequence

I am reworking an old HP desktop. The original hard drive was starting to go on my daughter's computer so I bought, cloned and installed a new hard drive on it. I am trying to install the old one hard drive which has windows XP as its OS as a second drive. When I start the computer without that drive, it opens and runs Windows 7. If I add the second hard drive without shutting down, the second drive installs and operates fine. If I then restart the computer it tries to run Windows XP, but the boot section of that drive is bad so the computer won't start up. I have tried changing the boot order to have the priority boot come from the Windows 7 drive, but it will not save the new setting and goes back to the Windows XP drive and will not alter the boot sequence. I'm thinking there is something on the 'XP' drive that is preventing the W7 drive from booting up. Any clues would be appreciated.

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.

 

Maxtor Hard Drive Beep

Maxtor drive beeps

Have a similiar situation using a DiamondMax Plus 8, 20GB Mfg Date 4/15/03. Drive used as a second system drive. Drive is recognized in boot menu but not in drive list. Drive is always connected. Computer started locking up for several seconds at a time. Chkdsk on drives and couldn't find that drive. Removed drive from bay to make sure connections were ok and heard the beeping. Shutdown and restart and never got to windows screen. Restarted several times then saw drive in boot menu and Windows loaded but Maxtor not in drive menu. When recognized in boot menu, computer will start but beeps and is not found.

Tried kicking it real hard but no improvement. Any suggestions?
