How to change kernel if grub not showing

[Vangelis62]

My fresh install of Manjaro KDE runs with Linux57. All works fine so far but I want to move to Linux54 LTS for better stability. So I installed it via Kernel settings but I can’t change as grub is not showing at startup. It loads directly to Manjaro initial screen.

Hi!
Open a termminal and do
sudo nano /etc/default/grub
Edit the line with valor hidden to style and the line how define time to 3
Save the file with ctlr+o exit with ctrl+x and do
sudo update-grub
In your next reboot you’ll be able to see grub

Edit your /etc/default/grub and make sure you replace…

GRUB_TIMEOUT_STYLE=hidden

… by…

GRUB_TIMEOUT_STYLE=menu

Then run…

sudo update-grub

You will now get a GRUB menu.

Even if Grub is hidden, you should most likely be able to get to the menu by pressing the Shift key during boot.

pressing the Shift key during boot.

F8 also works. I found the shift key not always reliable.

Good to know that that is also an option. On my system F8 brings up the UEFI boot menu.
