Access Is Denied for C, Can't Boot

I have 2 partition of my HDD; C and D. C is the system. Recently I took my friends HDD (internal) and I connected it to my pc for a few days. I was running OS from my HDD. Everything was going fine. Today I disconnected my friends HDD. Then started my pc and it's not starting. Windows loads but instead of showing welcome it shows a blank screen. I tried safe mode but same result. Then I again attached my friend's HDD and made that my first boot. Pc started and I see that my c is not showing the details, Location Not Available Access is Denied. Also I got a Recyle Bin Corrupted error for my D drive (not the C drive which is denied). Is there anything I can do instead of a fresh re install or format my c ?

 

Well, besides being illegal, that is usually a very bad idea because the Windows on that disk is - was configured with hardware drivers for the hardware in his computer.

You can try a repair install.

 

I am sorry I didn't know that was illegal. I ran a check disk and used the Automatic Repair from a Win 8 recovery flash drive. It's working now. Thanks for the reply and thread may be closed.

 

Super! Glad it worked. Now backup your data, just in case.

It is important to note when you buy Windows, you are not buying the software, but a license to use it. While the files are stored on the hard drive, the license is applied to the computer the license was purchased for or came with. There are only a couple circumstances where a license can legally be transferred to a different computer, and a friend letting you use his boot drive (and license) in your computer is not one of them.

Anyway, again - glad you got it going and thanks for the followup.
