BSOD error 0x0000006B PROCESS1_INITIALIZATION_FAILED on boot

I reinstalled League of Legends because the patcher always gave me an error. However, out of complete stupidness I didn't uninstall the old installation first because I thought that it would simply replace the files. However, when the installer bar got to 100% it simply minimized. Then I closed the application from the task manager. I tried uninstalling it after a failed attempt to start it up. The same behavior as when I installed it. Then I tried reinstalling where it simply presented the InstallShield Modify/Repair/Remove menu and I selected repair. Nothing happened.

Then I tried selecting Modify, then seeing that the only option (called DefaultFeature) was unchecked. Same behaviour as install/uninstall. After seeing that it still failed, I uninstalled again. And after that I deleted C:\Program Files (x86)\League of Legends manually. When I tried installing LoL again it still thought I had it, so I chose repair. This time something actually happened, but it installed the whole game to C:\Windows. Seeing what was going on I clicked cancel and then started it up to try uninstalling it. However, I got an error message about something not being registered and then the minimization to I decided to let it repair completely. Then I uninstalled it and it gave only the minimization.

However, when I rebooted another application started up complaining about some library being absent. So I decided to do a system restore. After letting it complete I got a BSOD (0x0000006B(0x00000000, 0x00000000, 0x00000000, 0x00000000)) every time I tried starting up Windows normally or in safe mode. However, system recovery mode works, although the system recovery automatic repair does not fix it. After a bit of searching I found a Microsoft KB article about it (981833) and tried following the workaround instructions. Nothing happened.

I am using Windows 7 Home Premium 64-bit HP OEM and Ubuntu 10.04 LTS 64-bit installed with WUBI.

If you can't boot, it sounds like you need a system repair.

1. Get any Windows 7 disk.
2. Reboot while tapping F2.
3. Go into BIOS settings, and set your CD/DVD as first boot-able device.
4. Insert the Windows 7 disk into the drive.
5. Reboot.
6. Follow these instructions. "Recover Windows 7 from a serious error". Do not choose Install!
7. Choose REPAIR. This will not alter the program entries in the registry. You won't have to reinstall all your programs. It simply re-writes any original Windows system files.
8. You will be asked for user name and password, to access the drive.
9. Once REPAIR is done, reboot and do a check disk with /fix. This will repair any file, directory, or index problems.
10. After this, delete the game's directory.
11. Reboot.
12. Then, download a Windows 7 registry cleaner, and clean it thoroughly. It will remove references to the uninstalled game.
13. Reboot.
14. Reinstall the game.

I wish you well.
