I need to change kernel to 515
It is very likely that you still have the previous one (515) installed
and can simply choose to boot it.
Press ESC after the firmware init and you get to see the Grub menu.
Did you remove 5.15 or do you still have it installed? If the latter, just reboot and choose “Advanced Options for Manjaro Linux” in the GRUB menu. This will then pop up a second menu where you can boot into 5.15.
If you no longer have 5.15, you must reinstall it first.
sudo mhwd-kernel -i linux515 sudo update-grub
That second step should not be necessary, but it doesn’t hurt to explicitly update the GRUB configuration. You will then need to select 5.15 from the menu as explained here-above and boot into that one before you can remove 6.1.
If you do not see a GRUB menu at boot, open up
/etc/default/grub in an editor, change the line…
Save the file and then run…
Ok i will try, How do I know when the firmware is loaded?
Very shortly after power on.
There is usually a manufacturers logo and in the old days there also was a beep sound.
Just turn the machine on and keep pressing ESC
(repeatedly in fast succession - don’t just stay on it)
or do what @Aragorn just described
I go to the boot launcher if i do that
whatever that means - I have no better advice
it always works for me
Thanks it works how i can paste 515 as default
Please read his post!
You don’t put 515 anywhere.
You change that line as described, save the file, then run the command
… both as root (use the
sudo command - and be very, very careful what you write!)
On next reboot, you get to see the menu that you could not get by pressing
Your choice will be remembered on subsequent boots.
If you have the following line…
/etc/default/grub, then GRUB will remember your last selection and will boot into it automatically if you do not select anything manually. However, you may also want to remove the 6.1 kernel if it doesn’t work for you, in which case 5.15 will be the only kernel left on your system.
sudo mhwd-kernel -r linux61 && sudo update-grub
its not working and writes some sing like sparse file is not allowed
That could happen if you’re using
You’ve multiple options:
- boot up kernel
- change the default entry
