[SOLVED] I cannot boot my system after a force shutdown

Yesterday, when I am speaking, the battery of my notebook is reduced to 0 and it turns off automatically. At first, I thought it had malfunctioned (previously had experience with undetected battery) and restarted it. But the battery really ran out and the laptop shut down again about a minute later.
When I was preparing to use my laptop today, I found that everything in BIOS had been initialized. I roughly restored the BIOS based on my memory (turn Security boot off and turn CSM on), and the laptop was able to retrieve the boot option, but it kept showing this image

, and cannot do any other thing. If I turn the CSM opinions to all "Legacy only", then I can enter the "GRUB Rescue>" phase. I can use ls to list partitions from (hd0) to (hd0,gpt3), but I cannot find the filesystem in anyone.

Please help me. Thank you everyone.

To correct it, as long as I change the Video in CSM to legacy only, it will enter grub rescue mode afterwards.
That is:

error: unknown filesystem.
Entering rescue mode...
grub rescue> _

See Fixing a broken system. Start with boot using a monthly Arch ISO from a USB flash drive, an optical disc or a network with PXE. (Do not follow any of the rest of the installation guide.)

Thank you, can I confirm again, are you meaning that I need to use an archLive USB to mount the system for repairing Pacman? By the way, I have used other computer to read this hard drive, but I did not see any logs after the shutdown under "/var/log". What does this mean. Thank you again.

I tried using LiveUSB to perform the above operations. The good news is that I can use chroot to enter the system and it doesn't seem like anything has changed. But the bad news is that I used 'pacman -Syu' to update everything, but after I reboot, there was still no change, only a white horizontal bar (not flashing) appeared in the upper left area of the black screen.

Re: [SOLVED] I cannot boot my system after a force shutdown

Finally, I solved this program by using the archlive to reinstall the GRUB in my disk and regeneration the grub.cfg. After this reboot, everything run well.
