Hello everyone. I recently updated my EndeavourOS, and as you know, there were problems with grub.

I followed these instructions:

> (Grub 2:2.06.r322.gd9b4638c5-1) Grub Update Causing Unbootable OS On UEFI Systems A grub update today is causing boot issues on UEFI systems. It will make most systems unbootable so take care! with no intervention, the system will just boot directly into Firmware with no way to boot the OS. If you have this issue follow these instructions: First boot onto an EndeavourOS Live ISO. Ensure that you are booting the ISO via UEFI mode. Follow these instructions to chroot into your install: [ht…](https://discovery.endeavouros.com/system-rescue/arch-chroot-for-efi-uefi-systems/2021/03/)

But unfortunately I can’t `grub-install`. I am not experienced in OS management, and after a couple of hours of trying I decided to create this thread for help.

This is an output of `sudo fdisk -l`:

I am right now sitting from live boot of my USB with an EndeavourOS.  
After trying every single combination many times, and then running `sudo arch-chroot /mnt`, I was able to chroot: after running `ls /home` I get my user directory.  
However, running `grub-install` gets me this message:

```auto
Installing for x86_64-efi platform.
grub-install: error: cannot find EFI directory.

```

I am very sorry if I did something incorrectly. I didn’t sleep for last 26 hours and there is an important work currently on my OS. Would appreciate any help I can get.

Thank you in advance.
