Grub won’t install with Arch Linux

I’ve been trying to install Arch Linux while dual booting windows on my laptop but upon trying to install GRUB, it gives me this error.

Installing for i368-pc platform.
grub-install: warning: this GPT partition label contains no BIOS Boot Partition; embedding won't be possible
grub-install: warning: GRUB can only be installed in this setup by using blocklists. However, blockists are UNRELIABLE and their use is disc ouraged...
grub-install: error: will not proceed with blocklists.

I ran a command to open up a menu to install arch linux,

pacman -S wget pacman-contrib
wget archfi.sf.net/archfi
sh archfi

I then used the menu to partition my disk to FAT32 for the EFI and then EX4, and mounted it using the menu.
I’m using a HP laptop that I have had for 4 years I believe.

EDIT: Something happened to the USB where I had to use a MBOK key, and now it gave me more options in the install menu, It says GRUB installed, currently testing.
