[SOLVED] Grub doesnt appear in UEFI Bios

Hello, when I install Arch it doesnt appear in my bios boot options. I installed it two days ago with windows 10 without a problem. However I decided to completely switch to linux, but now that I have to create my own boot efi esp it doesnt work. Here's how I installed it:

Created partitions on /dev/sda and /dev/sdb with gdisk

/dev/sda1 550M EFI System
/dev/sda2 8G Linux Swap
/dev/sda3 103.3G Linux filesystem (this is my root)

/dev/sdb1 931.5G Linux filesystem (this is my home on seperate hdd)

I formatted the partitions

mkfs.ext4 /dev/sda3
mkfs.ext4 /dev/sdb1
mkswap /dev/sda2
swapon /dev/sda2
mkfs.fat -FAT32 /dev/sda1

I then mounted the partitions

mount /dev/sda3 /mnt
mkdir /mnt/boot
mkdir /mnt/home
mount /dev/sda1 /mnt/boot
mount /dev/sdb1 /mnt/home

I installed base

pacstrap /mnt base

I generated an fstab file

/dev/sda3
UUID=c8d4f81f-1bc6-4398-8132-62cfae7e4929 / ext4 rw,relatime 0 1

/dev/sda1
UUID=90E0-8F3C /boot vfat rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,utf8,errors=remount-ro 0 2

/dev/sdb1
UUID=0139ca22-643b-4781-af61-44480fe1dc81 /home ext4 rw,relatime 0 2

Then arch chroot

arch-chroot /mnt

I did timezone locale and hwclock hostname and passwd according to wiki.

Then I downloaded intel-ucode, grub and efibootmgr
Then i installed and configured grub

grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id=GRUB

grub-mkconfig -o /boot/grub/grub.cfg

I didnt get any errors.
Then i reboot and its nowhere to be found:

Welcome to the arch linux forums solarpear.  Thank you for the detailed post.  Please boot the installation media again and check the output of `efibootgr` does it contain an entry for grub?

Re: [SOLVED] Grub doesnt appear in UEFI Bios

Please try GRUB#EFI_default.2Ffallback_boot_path

Thank you so much, this works! I really should read the wiki better! But it in the while loading it said the swap partition failed, any idea why this happened? https://i.imgur.com/43eLCMq.jpg
