Ok let me take a deep breath before I begin...
So this all started with running NewSID from SysInternals on my Vista64 machine. Yes I knew the risks, but it seemed 50/50 from what I had read on other forums around the Internet so I went ahead and took my chances with it.
Sure enough, NewSID hung up just like a lot of people said it would, and I was forced to kill the process and restart. NewSID seemed to do its job, as my PC thought it had been started for the first time, only some things were very odd.
My original Administrator account had been demoted to a guest account. This is the only account available at my log in screen. Looking under my Users folder, I see my old user account folder jakt, and a second folder called jakt.jakt-pc. (This is in the format of <user>.<domain>) All my data remains. Files are all there, programs all still run fine, drivers still intact. Under my Local Users and Groups in Computer Management, I see only two users in my Administrators usergroup. S-1-5-21-XXXXXXXXXX-XXXXXXX-1000 and S-1-5-21-XXXXXXXXXX-XXXXXX-500. I believe this is my previous SID before running the NewSID utility. No clue where this came from, or how to log in under this account, or if it is even possible to use this account.
So...after a few hours of messing around and unsuccessfully being able to restore my old account to Adminitrator priviledges, I figure I am just going to try and undo this entire operation.
First, I try to start System Restore. I was not so confident to not create a restore point before attmpting to create a new SID. Sadly, this does me no good as I am greeted with an error on start up of System Restore which reads, "Class not registered (0x80040154)". This repeats endlessly and there is no getting in to System Restore. Bummer.
Ok fine, we will just do this Rambo style and insert the installation CD I said to myself. Again I am greeted with an error message. "0x000000e9 I/O error" . It goes on to say something about errors with removable storage or hard drives or cd roms which may be failing. Well I dont have any removable storage connected, and I am pretty sure my hardware is good to go. Anyways, I am guessing the disc is bad. I tried to get the autorun.inf to load in Windows and it gives me corruption error messages there, so I guess the disc is bad. Double bummer.
I also tried doing the whole F8 thing at boot up and looking for some options there and there was nothing that seemed helpful. Triple bummer. :sa:
I guess my question is, what now? Honestly I wouldnt even mind reformtting at this point. I would rather not, but I have all my important stuff on a separate partition so its no biggy if I have to. Although that will be difficult when my disc wont even take me into Repair/Install. I am really just looking for a way to elevate my original account to Administrator priviledges from a guest account, or some way to run a repair on my Vista installation and get things back to normal or how I had them before all this, also diffucult without a working Repair disc. Any ideas?
Sorry for the novel, but being a PC fix it man myself, thee is nothing worse than those who provide too little information.
