I have an EFI system. I am able to boot from live USB in EFI mode.
However, when I try to install GRUB, system reboots and I see "GRUB" which also appears every time I press any key.
I was able to install EFI BOOTMGR when installing Windows 7. I still had to fix bootloader. When uninstalling it, I had to remove two "Windows Boot Manager" variables and one "BootOrder" (IIRC) on GNU/Linux. Every time my system rebooted, but variables were removed.
Is it possible to manually install GRUB on this system? How?
