I was playing with grub on my computer a bit more. Then I tried to reboot and I can't enter my operating systems (windows and Ubuntu). It looks like I've rewritten something very important because ut only shows me grub command line and I don't know how ti boot. I've tried to set root and then load vmlinuz, but it tells me that I need to specify some root option correctly. I was doing a lot of things with grub and I don't remember every think.I just remember that I tried something like grub-mkconfig recheck. I was also editng grub.cfg. I have also tried to read grub.cfg by cat and it looks normaly.

Have you tried to boot with a LiveCD, and fix with Boot-Repair?

sudo add-apt-repository ppa:yannubuntu/boot-repair
sudo apt-get update
sudo apt-get install -y boot-repair

boot-repair

It is straightforward to use, and worked for me before. basic UI

and it allows yo to change kernel options as well: advance UI
