Access denied to disk drive System C: & D:

[bbamse]

Hello. 

So i was going to restrict what my guest account could access in the files system. I changed the rights to open the disks C: and D:. The C: drive is system windows drive. 

Now here's the case .. I locked my own ass out  I know, how cool im i  cheers. 

It seems i lost my own admin right's and now i have problem running programs bevcuse c drive is in lockdown. 

I would like to crack it open. Letæs have fun.

Anyone?

Only I can think of is to place the disk containing system partition in another computer where you have administrator rights and fix the permissions. So you are able to get to the data.

 

But a windows installation with broken permissions is not good and will cause a lot of problems. So preparere yourself for a reinstallasjon.

Hello, Tnx. 

 

that can be an sulution to it. I am however hoping to find a solution aroung it. 

 

I can access the CMD with full rights when i run it outside login. So i made it so i can accsess cmd from loginscreen. 

 

Since i have access to all files and CMD, should i not be able to do a fix?

All user rights ownerships is tedious and complicated when it comes to system protected directories like the two .\Program Files\ Windows folders User profile and all subfolders of theese . There is no 100% quick fix the latest windows versjon I'm aware of.

 

Assuming you run Windows 10 , a better solution would be a windows upgrade on top and select to "keep files and settings".

This would fix the broken ownerships and user permissions.

 

I can't guarantee all is fixed for your situation but you might want to consider this as part of the approach:

Windows will not update couse it needs access to the disk and admin rights to do it. So it looks like im am on a lower level admin, even tho it is the hidden one and i have recuired @takeown@ over C drive and system32. Still tells me i need to be POWER USER. 

 

The update will not work as per now.

I do not think so when you start this upgrade of course offline from the installation. Boot from install media.

The install will then run with full access privileges.

That could actually be. Then i would need antorher computer and create a bootable device. Ofc, you said it, when im not IN LOGIN i have full accsess in CMD, it is only after LOGIN the problems occur. 

 

Im am a bit curious tho, how i could do it if i did not have another PC at hand.

You need access to a windows based PC and a 8GB usb stick .

Then you download media creation tool and create the usb as a windows 10 installation media.

Just make sure to "compose" the exact same windows version as on your PC you are going to use it (match license).

Also use the same base language .

Can you convert to fat32?

So what i did: 

 

- Got into PC repair mode

- Changed the file name of CMD to work on the setch command (tapping shift 5 times)
- Restart

- Got to windows login screen, here i hit the bleep to get the CMD running

- Activated the hidden user account and retreevd password to the other account be using /random. 
- I also used the command "takeown" to add rights to the local administrators group over C://windows/system32

Result: FAIL (fail to take own of C: & D: disk, still locked)

So next i downloaded new OS on another machine and installed it.

Result: Positive 
- Go control over C disk (dah, i just deleted the thing, so  you know, it happend) But antoher thing
- when i had this under control i now could force ownership of D: disk, where i had my files stored. 

So gratz to me and tnx for all help and comments on the way guys! 

Now i am going to do the same thing once more. Couse im am sure i could get thru without installing new OS, since i had control to the CMD on login and DOS. if you want to taggle along, say hey. tnx again. exuse the english.

Did you have an idea on a fix without reinstall?

If you connect the harddrive to another pc, and use a partition software, then maybe it can convert to fat32. If you got files bigger than 2G you will have to use exfat. It might work...
