I used to press F8 on Windows startup when I could start my Windows 7 to get to system restore option. Now Iam not able to get into Windows after I installed a certain update, so Iam pressing f8 key to get into boot options screen and system repair then system restore but nothing happens, it goes stratght into uefi bios where I cant find any system repair option. Anyway this way Iam not able to start my Windows anymore, I need to restore my system to the point before the update was installed. Any advice?
