I’ve been trying to install 7 x64 on my laptop for the past 2 days with no avail. The laptop has a 7700HQ with HD 630. I was able to start the installer from a USB stick by using UEFISeven, but after the installer reboots for the first time it no longer boots to continue. I made sure that the EFI being booted on the drive is uefiseven renamed to bootmgfw.efi, with the original bootmgfw.efi being renamed to bootmgfw.original.efi. I have provided a log from the verbose section, which shows that it unlocks the region fine. I’ve also tried the method of disabling vga.sys and vgapnp.sys and modifying the registry (http://reboot.pro/topic/21108-install-wi…l-gop-hardware/), but it did not help either.
