Help ! Vista Startup Repair Loop

.Hi, I'm using Vista Home Premium and is experiencing the Startup Repair Loop. I'm actually still using Vista SP1 and tried to install .Net Framework 4 for a program which then triggered the configuration of updates upon reboot. This configuration never made it past 19% in stage 1 (stuck even after half an hour later). A force-shutdown and reboot was attempted and the configuration actually made progress this time but suddenly stopped and rebooted into the Startup Repair screen which displays the "cannot repair this computer automatically" error and continues to do so at every reboot.



I've tried the following in reviving this pc:

1. All f8 upon start up options (safe modes just lead to the startup repair again)
2. This solution: Startup Repair Infinite Loop Recovery - Windows 7 Forums
3. Chkdsk (no errors found but if I schedule the check after reboot, it doesn't happen and the sfc scannow doesn't work either)
4. Memory Diagnostic Check (no errors found)

Update: I attempted to disable the Startup Repair upon reboot by typing this into the cmd: bcdedit /set {default} recoveryenabled No

The only result was that upon reboot, I got to the Windows Boot Manager screen saying that WIndows failed to start. They asked for my Windows Installation Disc (which I can't find) and the following is shown as well:

File: ntoskrnl.exe
Status: 0xc0000098
Info: Windows failed to load because a required file is missing, or corrupt.

But I can still access the f8 options upon startup.

I do not want to lose all my data. Any help or advice is appreciated.

Solved:
Burned Ubuntu Live ISO into CD (tried with USB but got boot error all the time) and installed the OS alongside with Vista.
Backup-ed all the data and deleted Vista away (piece of crap) with Ubuntu as my main OS now.
