Hello, I've already solved this problem on Artyom's laptop. The problem really affects UEFI and GRUB. Solution of the problem: 1. Get this error (just install the system) 2. Reboot the system from drive with installation image 3. As soon as you'll boot to the GRUB, press C and write: set root=(hdX,gptX) where hdX is your OS hard drive gptX - root partition. On the monoboot it'll be gpt2; also you can see your filesystem with "ls /", hard drive with "ls", see which version of the kernel you have: ls /boot/; then write: linux /boot/vmlinuz-kernelversion root=/dev/sdaX where X is the number of your partition(matches gptX) initrd /boot/initrd.img-kernelversion(it is located in the same place as the kernel) boot The system will start, after entering the system, open the terminal anyway, write: sudo update-grub2. Reboot. Now, the system'll start without any manual interruptions. Thanks for attention!
