I have installed Linux Mint on notebook with Windows 8.1. I didn't install grub on /dev/sda and installed it on /dev/sda5. After booting to Windows I tried to add Linux in Windows bootmenu using EasyBCD. But something went wrong and I could not boot anything. I installed grub to /dev/sda and now I can boot to Linux. When I run command
sudo update-grub2 I see:
Found Windows Boot Manager at /dev/sda1@/EFI/Microsoft/Boot/bootmgfw.efi
If I try boot to Windows I see black screen. Is it possible to recover Windows bootloader from Linux? Or maybe I can do something to boot to Windows from grub?
