So I've decided that I finally want to get Windows 8.1 which I couldn't install because of having my Users folder in a separate drive, even after creating symlinks to the system drive. I've found this guide and followed it. At the point with registries, I've had four S-1-5-21 entries, ending with 1001 to 1004, so I deleted the 1001 one (and didn't forget to export the whole ProfileList entry before, to the C:\Temp folder). Also note that there wasn't any ending with .bak, as many guides presume. Then, I went into account settings and created a new one called tempusr. After that, I've logged out and saw 2 accounts now, my former one and also the new tempusr. But after clicking any of those, I've received a message:
"User Profile Service service failed the logon. User profile cannot be loaded".

I thought that I need to restart now but after booting up again, the same thing happened. So now my computer is quite bricked and I can't log in to any of those 2 accounts. I've Shift + restarted to get into the service menu and tried to boot into safe mode, but all 3 modes (normal, with network, command prompt) resulted in a blackscreen and the LEDs on my keyboard going on and off with 1 sec intervals. Reverting to an earlier point didn't work either and neither the automatic repair did.

So I went directly into the CMD mode by clicking Troubleshooting - Advanced - Command prompt (translated, may differ). Surprisingly, this mode works. It asks me to pick one of my accounts- the former one and a tempusr account. I should also mention that both my default account and the tempusr one were an administrator type. So i log in through my default one (although there is no difference when logging as tempusr) and after typing in the regedit.exe I can see that all those long strings, from 1002 to 1004 are also gone, even although I haven't deleted them, and that only the 3 short directories of S-1-5-18 to -20 are there. After importing the registries and exitting the thing, nothing gets solved and by running up the CMD thing again, it seems as if nothing has saved aswell. I think it's happening because of the X: drive, which gets removed after I exit the thing. The problem is that I can't normally switch over to the D: or C: drive, the X: is still on the beginning of the command line. I even tried opening the C: drive's cmd.exe manually by opening a regedit, pressing import, navigating to my C:\Windows\system32 and running it as administrator from there, which worked. But again, opening the regedit.exe from there, gives me the same results...
Some guide was also suggesting the chkdsk command which resulted in no errors when applied to my system drive and didn't fix anything.


So is there any way to fix my computer without having to reinstall everything? I also have the disc, if that's needed for something.

So I finally fixed it! There was one thing that I overlooked, the File -> Load Hive option. Because the Import registry function still affected only the old one, and there is no copy option, I had to rewrite all those DWORDs and other values myself. But the result was satisfying enough- it WORKS!!

Everyone who is having this painful problem, don't give up and don't refresh your Windows installation for this small problem, just refer to this awesome guide:

I think this should be marked as a solution aswell, I forgot to post it as one and now I cannot remove this
