Was going through a friends laptop which had 3 AV's installed on it. After successfully uninstalling Norton 360 and Avast, i moved on to AVG. Uninstall never completed and after waiting 30 minutes, i powered off. Now i get to the windows loading screen and it just hangs, same thing with all options under Advanced Boot Options. Safe Mode hangs at "Loaded: \Windows\System32\drivers\avgardisk.sys" No matter how i change boot options in the BIOS, this thing will never boot off of any USB stick i throw at it. Ive tried various manufacturers and sizes from 8GB to 64GB, Linux distros, Hirens Boot USB, and a Windows 7 ISO. I made a Windows 7 Repair Disk and put it on a CD-R and it wont boot. It will boot from a Hirens Boot CD i made. Ive used Rufus, Yumi and Windows 7 USB DVD Download Tool etc. Im hoping to do a system restore prior to when i tried uninstalling AVG, any suggestions on how to accomplish this would be appreciated. I have some DVR+R disks coming in tomorrow and will try some of the bigger Linux distros just to easily backup some files to a USB flash drive. If using system restore isnt an option, ill try to backup files and do a clean install. May look at slapping Windows 10 on it at that point.
