I am update my system and now fail to start

How can i fix this issue

Did you search the forum before posting? The solution can be found at:

Edit: sorry @MeuKey - I just saw that you did post in the above thread. Make sure that you don’t put the “XXXXXXXXXXX” in your /etc/default/grub file - that text is just meant to indicate that you should leave whatever else is already in the grub file there.

I try that but i still have this issue

And i am dont know what to do
