Win 10 installed on separate hard drive changes win 7  

I installed Windows 10 on a separate hard drive in my computer to keep from messing up my Windows 7 installation. It appears windows 10 still makes changes to windows 7 even on a separate hard drive. See attached picture. I can not correct this using the system repair disk or the original install disk because it tells me it is the wrong operating system any idea how to correct this? I tried to make a new system restore disk and it tell me the disk is for technical preview x64! even though im making it in windows 7. (See Pic) The disk windows ten was installed on was removed from my machine when I tried to make the system repair disk from the picture.

After a situation similar to yours, some years ago, I was forced to formulate my own Rule concerning two OS's on the same PC.

If one OS can see the other OS, it will have a tendency to mess with it... changing things it doesn't like and deleting things that it thinks are unnecessary. More specifically, One OS, deleted all the restore points for the other OS.

So my new Rule is, "never let one OS see another OS on the Same PC".
On this ten year old desktop that I'm running Windows 10 on right now, I have two other drives with OS's on them, but.....
this drive is the only one plugged in. The other two have NO data connection to the motherboard, so they are completely safe.

I can't tell you how to fix your OS that has gotten messed up, other than do a Restore from a Backup file.
If you don't do backups, shame on you! If you can even boot up to that OS, then try to do a System Restore.
Failing that, sounds like you're in deep doo-doo.

Good Luck!

TechnoMage,

Lesson learned! The restore points appear still intact, Thankfully! I do backups frequently, To frequently, automatic backup ran last night at 2 am erasing the backup from last Sunday morning. I have run windows and linux in the same box for years with no problems, but never 2 windows systems. I have learned my lesson.

Alphanumeric,
Yes was powered up and connected. Didnt expect the change that makes a sys repair disk for windows tech preview instead of windows 7. I know for next time. Use and old box with nothing on it. Does anyone else see striking resemblance to linux in some of the system folders and App store?

Hi and welcome to TenForums,
Yep you'd have to remove the drive that 10 exists on then use this process,
Startup Repair - Run 3 Separate Times - Windows 7 Help Forums
After testing it you would format and re-install with the great advice already given :)
Cheers.
