Comment 84 for bug 1829620

@bellengc, you'd need to open up your Terminal to make a more permanent edit to your grub bootfile. Once you have the terminal open, type in:

cd /etc/default
sudo vi grub

This will open up a text editor in your terminal. You're going to be making edits to your bootfile so it's a good idea to copy/paste a back up of this file in another text file.

Near the top of the file you should see a line that looks like:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

Go to this line, and after whatever commands are in there, add "dis_ucode_ldr" to the end. If you haven't used vi, you'll need to first hit "i" to go into edit mode, then start moving around and typing. When you're done, you should have a line that looks like:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash dis_ucode_ldr"

To save your changes and exit the editor, type ":wq".

Now run the command "sudo update-grub". Now, next time you boot up, you should be good to go.
