Windows 8.1 Automatic Repair Loop problem. Can't fix need help.

[General J]

So when I uninstalled Avast in place of a different antivirus software, apparently Windows didn't like that.

I tried to shut down immediately because I was told that the backing panel to my mobo came off (Worried it would be dangling by a fan or something). There was an error message preventing me from shutting down and I didn't remember what it said. Nothing along the lines of "turning off your pc will fuck everything up" so I just power cycled it.

Well hey funny thing, the backing panel was not off at all. It was totally on there the whole time so there wasn't any rush to turn the computer off at all!

Now I'm getting the Windows 8 Automatic Repair Loop and I can't seem to do shit. There are no system restore points oddly enough.

I ran the command prompt and did the chdsk thing. The log turned up this:

Root Cause found:
-------------------------
Registry is Corrupt

Repair Action: Registry roll back
Result: Failed. Error Code = 0x2

Is the only one with the message. There was 1 thing in the other two areas but said

Root cause found:
----------------------
Startup Repair has tried several times but still cannot determine the cause of the problem.

And this is where I'm stuck.

Where do I go from here? Is there anything that can be done? Can I manually delete the Avira program from the command prompt here?

Saving the data the main goal here as there were unbacked game projects on it :(

Unless you got Windows 8.1 on a disk instead of upgrading from Windows 8 I doubt the install disk version of startup repair can help, if you do have an 8.1 disk you could try that.
If worst comes to worst you should be able to boot a live linux disk and copy the files to some other disk (even another internal disk would worK) and reinstall.

Your best bet is to replace the hive. If you think Avira is the root cause, you can try using the CLI.
The one downfall is the services may not be active, or unable to run.

You can run:

net start msiserver
msiexec /x <Installer Package Path>

my msiexec syntax may be wrong, so if someone could review that.

You may also have to add the MSI Service to your registry.

REG ADD "HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Minimal\MSIServer" /VE /T REG_SZ /F /D "Service"

Run this then the other 2 commands.

If saving the data is the main goal, then why don't you use a Ubuntu Live cd?
Run this (from boot), get a usb drive plugged in and copy your shit to this drive :happy:

To save data this indeed would be the easiest way. If this is the way you want to go, have a look at [url]http://www.howtogeek.com/howto/windows-vista/use-ubuntu-live-cd-to-backup-files-from-your-dead-windows-computer/[/url]
(It says Vista in the URL bit it applies to all OS's really..)
