Windows 7: Restore Access Permissions on C: Drive after changing in cmd

Restore Access Permissions on C: Drive after changing in cmd

So, I'm an idiot. I need someone to help me reset ownership and permissions for the c: drive on a hdd. I'm not well versed in cmd so I can't seem to figure it out.

My bf's laptop overheated (so I thought, he was streaming a baseball game, not much else I think, when it shut down unexpectedly last night) and wouldn't reboot. It displayed the Toshiba logo, but when that disappeared the dos type text cursor appeared and then stopped moving, where it normally blinks a few times before showing the windows logo, logging on, etc.

He's using a Toshiba A665-S6095 laptop purchased in 2010. HDD most recently replaced about a year ago with new drive. Running Win 7, i5 processor. Used mostly for web surfing, word processing, nothing taxing.

I somehow got it up boot into windows from the 'incorrect shutdown' menu (repair, safe mode, start noramlly, etc.), and decided to restart thinking it would be fine, but again wouldn't boot just like last night. I connected it to my own laptop with a sata cord and was able to see the drive and all its contents. I ran chkdsk in cmd and found no errors, but when I tried to run /fixboot it gave me an access denied error. I did some searching and thought I could change permissions to get recboot to work, and found these instructions (method 1):

Access denied on external hard drive. - Microsoft Community

I should have known better when the cacls promt came up with ARE YOU SURE? but I did it anyway.

After this I put his hdd back in his laptop and tried taking out the battery and draining what was left, which enabled me to boot back into windows normally. Found out I f*ed up royally with permissions. Won't let me do anything that requires administrator priviledges and I can't see or change user accounts or their permissions through c: properties. Can't system restore.

I really have two problems here - booting and the permissions access, but I feel that if someone can help me return permissions back to default settings I can do the rest.

PLEASE HELP. Let me know if you need more info.

Boot into System Recovery Options via F8 or disk to run System Restore as far back as necessary.
