Solved Win7 won't start - "0xc000000e bad driver" error

[nomagnolia]

It was working fine yesterday, but this morning it never got past the Win7 logo on a black screen (usually it boots in 20 seconds or so). I swapped the SSD boot disk with the SATA disk it had replaced in 2013, and this boots up fine. (I tried booting from the Win7 DVD when the SSD was still plugged in: system restore had no available restore points, startup repair failed to fix the problem.)

I've now got the SSD plugged into a USB3 port on a spare laptop, and can browse the contents of the disk. Looking into this error it seems it can be caused by a corrupt BCD hive, but I don't know how to fix this.

Is it possible to repair a Windows installation if it's on what is now an external disk? Do I have to boot from the DVD to do this? (Currently I'm working on the spare laptop which the SSD is plugged into, and the broken machine has booted into its old copy of Windows on the old SATA disk, but obviously everything's nearly two years out of date, so I'd rather get the SSD version back on its feet if possible!)

There is a problem with AVG at the moment (since yesterday). You simply need to uninstall it. Let me try to find my post in another thread.

Ah, thank you! I renamed the folder in Program Files (x86) to _AVG (with the drive plugged into a spare laptop), plugged it back in to the main laptop again as C:, and it's booted up immediately.

We're now removing (paid!) AVG from all our machines here and replacing it with an alternative....
