Vista Not Booting

[lacolocho]

I have a Dell Inspiron 1720 with Windows Vista. 4Gb RAM

Like lots of people I've been having problems with Firefox 3 randomly crashing due to Data Execution Prevention.
In an attempt to fix that I ran the following command to turn DEP off for Firefox: bcdedit.exe /set {current} nx AlwaysOff

After running that command I got a popup error that Superfetch had stopped working. This had happened in the past a couple times, not sure why.

I rebooted my system and it didn't boot up. Tried it in Safe Mode and using the setting from the last successful reboot, no luck.

Booted to the Windows CD and tried the startup repair. It found a problem and supposedly repaired it (didn't jot down the details), tried to reboot again and still no luck.
I ran the startup repair again and this time it found a problem but couldn't fix it. I got the following details:
Startup repair cannot repair this computer automatically

Problem Event Name: StaqrtupRepairV2

OS Version: 6.0.6001.2.1.0.256.1
Locale ID: 1033

Then I tried to run System Restore, but it says "No restore points have been created on your computer's system disk."

So, it sounds like I'm pretty ****ed. Any ideas? What could have happened?

Hi,

I haven't used Vista's CD repair yet but from experience with Windows XP and Server 2003 there was a recovery console option when reparing from CD.
Look for the recovery console when you boot from the Vista CD and when you get into the console look for the bcdedit command. Try to reverse what you did and hopefully you'll be able to boot Vista again.

EDIT:
Run

bcdedit.exe /set {current} nx OptIn

I'll check this out tomorrow morning after some good night sleep.


Good Luck,
