Cannot switch to another kernel

I have 2 kernel linux-lts & linux , currently runing on linux-lts .  My laptop is freezing a lot , every hour it gets hanged and i had to hard restart it . I thought to switch to another kernel that my system have but while booting into it , it shows the following error:

Starting version 249.4-1-arch

/dev/nume0n1p2: recovering journal /dev/nume0n1p2: clean, 612682/15237120 files,

[FAILED] Failed to mount /boot.

20509876/60918272 blocks

[DEPEND] Dependency failed for Local File Systems. You are in emergency mode. After logging in, type "journalctl -xb" to view system logs, "systemctl reboot" to reboot, "systemctl default" or "exit" to boot into default mode.


Why its not mounting to /boot , what i had to do ?

Re: Cannot switch to another kernel

Typically because it can't load the vfat module what is typically because the booting kernel matches no installed kernel what is typically because either you forgot to mount the /boot partition when updating/installing the kernel or are in fact not booting from the /boot partition but the root partition but installed the kernel image on the then mounted /boot partition.

Check "uname -a" in the emergency shell and compare it to "pacman -Qs linux"

Re: Cannot switch to another kernel

Now you're hijacking your own thread.

seth on the other thread you hijacked wrote:

Open a new thread, describe your symptoms as detailed as possible and post the entire journal for the freezing boot. (The ACPI error is very most likely insignificant)
