Boot option for EndeavourOS lost after yay

Good afternoon everybody.
Need help, please.
I have dual boot installation Windows 11 and EnOS in my laptop ASUS TUF A14. It happened when I did yay -Syu zoom because I wanted to install zoom in EnOS. Suddenly my laptop frozen and CapsLock button flashing red before it finish. Because it’s going for a while I forced shut down the laptop by holding power button. And then when I start again, the option in boot menu for EnOs lost, leaving only the option for Windows 11 and Reboot in Firmware. I checked in BIOS, the Linux Boot Option exists. I did a system restore with Timeshift but boot option still lost. Please help!
Thanks in advance

Start by Arch-Chroot:

Then reinstall Linux kernel:
sudo pacman -S linux linux-headers

I did that but it’s not working

Bootloader?

systemd-boot

wait, maybe I do wrong arch-chroot because when i do ls /home my username not shown, how can I know if I do the right arch-chroot?

As the guide I posted stated you will need to mount your filesystem. then chroot the mounted dir

From the live session, post the output of the following commands to begin with:

sudo parted -l
efibootmgr

sorry my bad :laughing:
I retried @grymphen advice and it worked, my mistake was when arch-chrooting is when I tried to mount /efi, I mounted live session /efi
Thank you everybody :grin: especially @grymphen , I’ll mark that answers as solution.
