Hello

In short my computer refuses to start win 7, it tries to repair it, but fails. I have tried system restore point and restore to previous known working state but neither works. The computer will start in safe mode though.

Some background:
This started when my AVG virus software started telling me it could not update so I uninstalled it (or rather tried to update it by downloading a new version of it and trying to install it over the old, but this had some problems so I uninstalled it). I rebooted after the uninstall and the cycle above started.

At this point time I tried restoring the system to the point before I tried the "install new version over the old" and the restore was successful but the problem persisted. After this though, no restore point will work anymore, I just get

"unspecified error occurred during system restore 0x8000ffff"

Apparently the first restore really did work as when I started in safe mode, the AVG was there and I uninstalled it hoping it would help, but no.

I've tried running the Repair Computer option from win7 disk, but it wont work. I can not even try to reinstall win7 at the moment because I get this when trying to select any partition:

windows 7 windows cannot be installed to this disk the selected disk has an mbr partition table gpt

I know this is related to the fact that I have an UEFI motherboard, but the fact I can get to safe mode sort of confuses me.

Now the problem in not really that I can not find helpful things on google, but rather the fact that I can find too many so I was hoping if someone more experienced than me could point me to the right direction from that description.

Thanks for any help.

Kind regards,
Q

*Edit* After following some advice I was given I was able to achieve 1 normal boot to windows after uninstalling AVG with a specific uninstall tool from AVG web site. However after that the problem came back exactly as it was. So things seem to point to AVG, but I'm at a loss on what to do about it

Thanks for the hint. Unfortunately it did not help (no problems found) but I did learn of a new thing :)
