I want to change boot from linux 6.7 to linux lts, or at least have the option to do so. As in “https://discovery.endeavouros.com/installation/systemd-boot/2022/12/” which I’ve done successfully on my desktop. My 15 yo Asus laptop is different somehow. There is no /efi so no /loader and no /entries to view or /loader.conf to edit. Here is my info:
inxi -FAZ --no-host | eos sendlog. Thanks for any input.
That machine is probably using grub.
Start by running sudo grub-mkconfig -o /boot/grub/grub.cfg that should give you the boot options for your additional kernels.
If you want to set one as default, you can do that in /etc/default/grub. After changing that file you need to run the above command again.

Ok, thanks for the quick reply! Not sure how to edit the grub file, I will look at it tomorrow. Been at it for awhile. Thanks so much.
You can find info on the Arch wiki or their GitHub also has instructions to do this.

Thanks, will check it out.
You can use a text editor such as nano to edit the grub file and then save the changes before running the grub update command.

There are more than one way to make LTS the default, but I’d suggest you add line
GRUB_TOP_LEVEL=/boot/vmlinuz-linux-lts
into /etc/default/grub.
Then run the grub-mkconfig command that @dalto suggested.

Although this is not what you asked, you can also edit your grub file so that it defaults to whatever kernel you used last. To do that, edit /etc/default/grub:
GRUB_DEFAULT=saved
GRUB_SAVEDEFAULT=true
GRUB_SAVEDDEFAULT is a line that is usually commented out towards the bottom of your grub file, so you can just uncomment it. Then run sudo grub-mkconfig -o /boot/grub/grub.cfg as recommended.

Note that savedefault works with ext4, but not with btrfs (at least last time I tested it with btrfs).
