1398222 2015-04-07 21:44:00 All of a sudden my brother's PC running Windows 8.1 decided not to boot, and choosing any recovery option, including Command Prompt and System Restore, tells me that there are no administrators on the PC (he is the only user).

After much Googling I was able to boot from a DVD and repair the boot files, which then allowed Reset to work - previously it complained of a missing partition. However I'd like to fix this without having to do a reset. Offline enabling the built in administrator account didn't help either.

Any ideas? I'm stuck now...

1398223 2015-04-07 22:05:00 What partition did it say was missing ? Also is this a name brand Computer Eg: HP or a self built ??

Had one similar yesterday, damn thing was a HP and the boot couldn't be fixed no matter what commands or repairs or reset were entered due to the mickey Mouse partitions HP set up. :angry

How did you try to enable it ?

Can't recall exactly, but I think it was a recovery partition. It's a custom-built PC.

By following this: 4sysops.com

1398225 2015-04-07 23:13:00 you dont need to go through all the rig-ma- roll Open a command prompt with as admin, and type in net user administrator /active:yes <Press Enter> then sign out and it should be there.

If you want to check the system for corruption have a read of www.eightforums.com Option 1.

You can also have a look in disk management and see if there are two partitions showing. Some say you can remove the 300MB partition, but it can cause all sorts of problems if you do. Thats what it may be looking for. A std Windows 8.1 doesn't actually create a restore/ Recovery partition, you have to do that manually.

I recall doing that from the boot disc, but it still didn't work.

Will either have a look at the rest when I get home, or make my brother do it. :p

1398227 2015-04-08 00:31:00 Activating the admin account from the DVD wont work ( usually) you have to be in the C:\Windows\system32 prompt.

If you re-look at the link provided, the instructions allows you to make the CMD available from within the OS, not from the CD. ( point/instruction #3)

If the Hidden partition has gone AWOL, then that will cause the boot error message. By running the repairs it will fix the boot options.(sometimes)

The commands given, because you mentioned:
I was able to boot from a DVD and repair the boot files, which then allowed Reset to work I assume you can boot into windows normally now.

As I mentioned got a HP here, similar problem, ended up doing a factory restore, the reset wouldn't work, nether would anything else. The HP had 7 partitions some duplicated when they shouldn't have been and no matter what was done it simply didn't want to play the game --- I showed it :p Reinstall ;)

Nope, I can't, hence why this thread exists :p

I'll have a better look later tonight and report back.

1398229 2015-04-08 03:44:00 Okay, so if the boot repair didn't work. just a thought, have a look to see what you actually have.

Boot from the Windows DVD, lets see if the system partition is actually there ( could be the main problem if it isn't)

Once booted, select the country etc, next window bottom left, repair computer -- then from Troubleshoot/Advanced/Command prompt.

Once open type in the following EXACTLY, nothing more, if you go playing you can wipe the whole drive, there is no "are you sure". press enter after every command. Anything in ( ---) are comments only.

type:

Diskpart (will take a few seconds to load)

List Disk

(Assuming you only have 1 HDD, it will be disk 0, if you have more select the main drive number)

Select Disk 0

List Partition


What you should See is two partitions, the 350MB and the Main. Both listed as shown

EG:6362

To get out of there, type exit ( twice)

1398230 2015-04-08 07:41:00 I get these partitions:

6363

1398231 2015-04-08 08:32:00 Looks a little similar to what I had but mine had 7 partitions, including a couple of Windows.

Before using the commands below , have a look to see if the volumes are actually listed as they should be.

In the command prompt, ( disk part) type list Volume

You should see as below, ( different drive sizing of course) the 350MB should be the system, while main partition should be Boot:
6365

Note: Volume 3 ----- V is a second Drive.

You can try repairing with the boot commands ( this is copied from another site)


In the Command Prompt window, type the command line BOOTREC /FIXMBR and hit Enter key
Now type the command BOOTREC /FIXBOOT and hit Enter key
Type another command BOOTREC /REBUILDBCD and hit Enter key
You will be notified with a statement The operation complete successfully
Type exit and hit Enter to quit Command Prompt
You will once again be displayed with Choose an option screen
This time choose either Continue to Windows 8.1 or Turn off your PC

Going out to do a urgent job so may not be back tonight.
