Windows 7: Taken Ownership over drive with Win7

Hi, i have 2 copies installed on different partitions, I usually use this (32 bit) version (not because it is better lol.) and a few days ago I was trying to save a word file trough the software to the HD, but i got the error 'a required privilege is not held by the client' message.
I downloaded and installed the Take Ownership right-click menu item from this site, and I used it on the partition with no success (it did what it said, but the software were still unable to save to the drive)
A day later I wanted to fire up my other windows 7 (64 bit), but right after I have highlighted and pressed enter in the boot menu, it restarted itself, so it could load nothing of the OS.
Questions are:
1. Can i get back that copy to life? Shall i change the owner again?
2. The error 'a required privilege is not held by the client' is still a problem.

Any help would b greatly appreciated

Did you set up a Administrative-level account when you installed the second Windows 7, and did you install correctly from the booted installer and not by running the installer from the other Windows 7? You will know this because the drive letter of the second-installed Windows 7 will not be C when you are booted into it.

Unless you don't trust yourself, I would run an Administrative-level account with UAC turned on - or try running the Program in question as Adminstrator by right-clicking on it's .exe.

Well, if you ran the change owner on the root of another drive with another copy of windows on it it's pretty well toast. You can probably boot off the install disk and do a repair install, it may reset the permissions. There isn't a single permission for the entire OS, there are dozens and they are set on individual files and folders all differently so you won;t be able to just hand set them back to a single user using take ownership.

As for getting that error when saving a file, where are you saving it? The root of the drive? Or in a windows folder or something? Try creating a temp folder on the other drive like D:\Temp then save it there.

Unless you cloned your user account, your user on the 32bit windows can't write to the user folder on the 64 bit one, windows will by default think you are two different users and block you from writing to most any windows folder on the other drive. Make a new folder and use that as a common folder between the two windows. Set it's permissions so that "EVERYONE" has full access to it.

Take ownership only transfers the permissions from an old user to your own, it doesn't allow multi user access to a single folder. But you can set that yourself in the permissions for the folder. If you need a step by step for that, let me know.

I have given up the second system and installed a new one on the same drive where it was, so now the problematic system is in the windows.old folder, which i will delete later..
Yes, I have an admin account and in the past I could save any files from apps to the root directly.
All in all I have 4 partitions (3+1) and which I have never installed OS on (1 of them) is still able to accept files and save them to the root.
(from my main system) I have C: D: E: and G:, C,D,E are on a single disk and G is a data disk
I am using os on C and D, and I have had one on G in the past, which I have deleted by now, but i am still unable to save directly on it (I dont mind the other 3).
On G: everyone has full access, and the owner is 'Administrators' just like on E:, which I can use with no problems.

Are you booting the Windows 7 DVD to install, following these steps? Clean Install Windows 7

Since you have a separate data HD, would you consider wiping the HD (of possible boot sector corruption) to clean reinstall from booted DVD following the steps above? This would give you a clean baseline.

In addition to the illustrated steps in the tutorial there are tips here which will help you to get a perfect reinstall based on hundreds done here: Reinstalling Windows 7

Unplug all other HD's and peripherals during wipe and reinstall.

Good ideas thanks,BTW im only interested in the 'a required privilege is not held by the client' problem.

I've never seen this arise on an install where the quasi-Admin account which is offered during install is set up, and then no further tweaking to the OS or permissions is done.

This is why I suggested getting a baseline wiped clean reinstall.

Save an image shortly after it's setup and running great in case you accidentally get tweaky.

If you are not logging in as an account that is on the computer that you are trying to save to, then enable the "Guest" account on that machine and give it permission to write to that folder.

This is where domains come into play. So you have a single account that can log into any machine and you can assign permissions to network accounts rather than just the local machine accounts.

Something you may play with is the ability to transfer accounts from one machine to the next. I.e. put your main account (With it's unique user ID) on all machines, then you can traverse your network with impunity I've not personally done this, but I have transferred my account from an old to a new machine. Best way to keep all your file permissions in tact and not have to use the take ownership on the new machine.
