[SOLVED] New installed kernels not showing in GRUB

I installed the LTS, Zen, and Hardened Linux kernels (sudo pacman -S linux-lts linux-zen linux-hardened) and when I look in grub or the advanced options, I only see the normal linux kernel. How do I make the other kernels appear?
PS: I noticed some weird things being said during the installation, such as "error: command failed to execute correctly", I put the log on pastebin, here https://pastebin.com/GP3FPmz2

Re: [SOLVED] New installed kernels not showing in GRUB

Did you update grub.cfg?

Off topic: you should install the relevant filesystem tools package(s), your log shows that fsck is not being applied during the boot process.

What was this "correct" command, exactly?

If you use ext4 you need the e2fsprogs package; consult the ArchWiki for the rest.

Re: [SOLVED] New installed kernels not showing in GRUB

no, I actually use btrfs, and I ran "sudo grub-mkconfig -o /boot/grub/grub.cfg"

Re: [SOLVED] New installed kernels not showing in GRUB

For btrfs you need btrfs-progs but you don't actually need it for fsck because btrfs is not fsck-able. Somebody should probably tell the mkinitcpio devs...

Please share the full output of `sudo grub-mkconfig` (using code tags). Thanks.

EDIT: you also need dosfstools for the EFI system partition.

You need to run it as root.

Re: [SOLVED] New installed kernels not showing in GRUB

The main "Arch Linux" menuentry GRUB shows you is for linux-zen; the other kernels can be found under the "Advanced options" submenu.

Sorry, that was obvious from post #7, I just didn't think it through

Re: [SOLVED] New installed kernels not showing in GRUB

I fixed it! after rebooting and remaking the config, it just randomly fixed itself? thanks!
