Windows 10: Hard Drive Wipe - Booting up Windows 10

When I logged on my computer this morning I found that my entire hard drive had been wiped clean - no pictures, documents, or any other files that I saved from the last year has survived. There was a blue error window that appeared before I logged in stating that Windows 10 couldn't find my user profile, but I didn't pay attention to it because it still gave me the option to log in. After that I can't find anything that I saved on my hard drive. I also can't go back to a previous version of Windows because updates happened over 10 days ago. I'm wondering what happened as this is a very new computer and what I can do to recover my files, because I'm not that knowledgeable about tech and this has left me worried about whether something like this will happen again.

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.

 

How to wipe a hard drive

Sounds good, but I can't load any cds upon boot or even in windows.

I tried to run Win XP pro cd my friend made for me. It wouldn't work becuase The software is so corrupted. The hard drive itself is fine I just need a way to completely wipe the hard drive of everything.

I don't want to just reinstall over the corrupt mess of windows. I want to start over not reinstall brand new OS and have corrupted programs, settings, or info
