Windows 7: Unknown BSOD from password crack attempt

Unknown BSOD from password crack attempt

Okay, I'm pretty sure that I've lobotomized my entire windows at this point.
I forgot my password to my account a few days ago, but luckily, I previously installed Kubuntu as an alternate OS, so I still had enough access to attempt a few cracks. (This was after trying to guess my password) First, I rebooted and tried the sticky keys hack. This caused the first BSOD. I rebooted into windows again and ran startup repair, but I still didnt have the password, so I switched to kubuntu. Kubuntu actually has an application to change the password from the SAM hive file, so I ran that. Tried to open windows, second BSOD. At this point, I thought maybe it was just an error caused by illegitimate editing. I tried the kubuntu hack again to no avail. A few days passed of me just using my alternate OS and not touching windows until today. I tried to log in again, and got a BSOD again without having done anything previously. I ran startup repair, and it failed. It said something about not being able to access some memory file... Restarted, and now windows wont even attempt to startup. It gives the startup repair "loading files", shows the non-graphical "windows is loading" and then blackscreens. It wont respond at all. I'm posting this from Kubuntu right now, as I can find nothing to do about windows.
Also, I have a built-in restore, but it'll set it to factory default. I'm not sure I want to resort to that quite yet.

I cant boot at all, let alone safe mode. Also, I'm no longer getting the BSOD, (Windows simply won't load), but when I did, it only flashed for a second before the computer crashed.

do you by any chance have a windows 7 installation disk?
If not you can het them from here:Windows 7 SP1_Refresh ISO - WinCert.net Forums legally and free, unactivated, try booting one from disk or usb and running the repair my computer option.
If you need any further instruction, just ask.

while u do this i'll be looking for a way to repair SAM...

Here's another link you can follow and try: Perform A System Restore Manually When Windows Is Not Bootable - Spiceworks
for the above they recommend backing up Sam, you decide if you want to or not. You should be able to use this method from kubuntu.

Thanks for your help so far, Ill try what you said, however, I do not have a disk drive (Ill try USB). Also, I double checked, the advanced options from F8 do not work, including safe mode and repair my system.
[EDIT] I'm downloading the disk right now, but I haven't the faintest idea on how to use it, so could you explain or give a tutorial link as well?

k First of all you have to make you're usb bootable, before you do this back up all the data on the usb.
Open elevated command prompt(Start>type cmd in search bar right click on cmd and run as administrator)
Type Diskpart
type list disk ( make sure you do not have any other usb's plugged in while doing this, you may format the wrong one)
type select disk ...(... stands for whatever disk you're flash drive is, you should be able to tell the differance thru size)
type clean
type create partition primary
type format fs=ntfs quick
type active
type assign
you'r usb is now bootable.

---Part 2---
1.using winRAR or 7zip if you have them, (if not you will eiher have to get them or something that can extract iso files, i recommend WinRAR, you shuld be able to find a download pretty easily) Extract the ISO to your USB flash drive.

2.Setup you're BIOS to boot from usb ( assuming you have previously installed kubuntu i'm pretty sure you know how to get into you're bios)

3.after booting your USB click the button that says repair your computer DO NOT CLICK Install windows, this is for a clean install of windows if you ever need one

4. This will start the Windows 7 System Recovery Options which contains several useful diagnostic and repair tools, one of which is Startup Repair

--As you can see i sort of clean up the mess i made and just put all the instructions in one post hope everything works out ok!---
and remember, if this doesn't work try this:http://community.spiceworks.com/how_...s-not-bootable from knoppix
