Problem is that Windows doesn't find any restore point?? I will perhaps try with True Image, did a backup about 3 months ago, perhaps that will work.

Ok, stupid True Image says that my backup is not an original True Image backup, also it's one, extension is .tib, or it's corrupted. My guess is that the True Image version I have installed on my other PC is older than the one I actually took the image with. Hell Yeah!!!

After making a bootable media now with the Trrue Image version I had (Home 2011), I had to validate the backup, and now at the moment it's recovering the partition. Hopefully it works, backup was from the 12th of April, so not that old, and there was not a lot of software installed after that, I only guess that I have to update some software again. Perhaps also Comodo Internet Security was not yet installed, so might have to do a fresh install. Will see. Anyway, if it works fine, it will always be better than doing a fresh windows install.

Worked out fine now with the recovery of True Image. Only had to update Windows files again (no SP1), and some software, Comodo was already installed. Gonna make a new backup now again, so when this happens again, I won't have to do all the minor updates again.

Gonna look into what the problem was, and how I can get around to avoid the errors when installing SP1. Found some advice what you should do first before installing SP1, but I still don't understand why I have to do it, when it seems to work flawlessly for other people?
