[SOLVED]Correctly partitioned FAT32 partition could not beusedasanESP

Hi all,
I bought Lenovo IdeaPad 5 Slim 14" (14ARE05) whose CPU is AMD Ryzen 7 4700U and tried installing Arch Linux to it, but encountered a problem while installing bootloader.

It seems like I did nothing wrong about partitioning my hard drive from seeing the output of some commands below:

# uname -a
Linux archiso 5.8.12-arch1-1 #1 SMP PREEMPT Sat, 26 Sep 2020 21:42:58 +0000 x86_64 GNU/Linux
# parted /dev/nvme1n1 print
Model: SAMSUNG MZALQ512HALU-000L2 (nvme)
Disk /dev/nvme1n1: 512GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Disk Flags:

Number  Start    Size   File system  Name                  Flags
 1      1049kB  538MB  537MB  fat32        EFI system partition  boot, esp
 2      538MB   512GB  512GB  ext4          Linux filesystem

But all my attempts to install boot loader were ended in failure.

# mount /dev/nvme1n1p1 /mnt/boot
# mount /dev/nvme1n1p2 /mnt
# arch-chroot /mnt

# grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id=grub
Installing for x86_64-efi platform.
grub-install: error: /boot doesn't look like an EFI partition.
# bootctl --path=/boot install
File system "/boot" is not a FAT EFI System Partition (ESP) file system.

What should I do for making /dev/nvme1n1p1 a valid ESP or is there other thing being wrong state?

Sorry for awkward English and any advice is much appreciated.

Your mount order is wrong. You need to mount your root to /mnt and THEN mount the ESP to /mnt/boot for the setup to be logically properly carried over into the chroot.

Right now you mask whatever you had in /mnt/boot with what's in /mnt and if you recheck with mount from within the chroot you should notice that the ESP is not mounted to /boot

Thank you very much for the advice.
I just have tried unmounting these partitions and re-mounted them in correct order then tried grub-install, ended in success.

Adding [SOLVED] label and thank you again
