GRUB error new install: booting in blind mode

I've just installed Arch for the second time, and everything went smoothly throughout the process except the bootloader installation. Long story short, whenever I boot into my SSD it sends me to the normal grub terminal (not rescue). Obviously, I set root, boot, and prefix to the given partitions/directories and then loaded the kernel (vmlinuz-linux-lts). However, attempting to boot from here gives an error about no suitable video mode being detected, and that the system is booting in blind mode, which freezes my screen and turns off my keyboard/mouse.

Re: GRUB error new install: booting in blind mode

Long story short

I would prefer the long version

Please list the exact commands that you used when installing, if you see a 'grub>' prompt then it can't find the configuration file. Use the set command to see where it's looking.

attempting to fboot from here gives an error about no suitable video mod being detected, and that the system is booting in blind mode, which freezes my screen and turns off my keyboard/mouse.

List the available video modes with

videoinfo

Then try

set gfxmode=$mode

Replace $mode with an actual mode.

I'll give you it before I go to try your solutions (or rather, as I try them out) when installing, I ran

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

then

 grub-mkconfig -o /boot/grub/grub.cfg --target=x86_64-efi 

(can't remember exact)

I essentially had issues where first my BIOS wasn't booting into the right partition (defaulting the to the windows partition which of course was also broken because of grub) after which we arrived at the point of this post

sorry for the partial answer, but grub seems to be using the EFI directory as the root directory as well, however I fixed that by setting root

Tried setting it to 1920x1080, same result

Re: GRUB error new install: booting in blind mode

when installing, I ran

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

You don't need to specify the block device for a UEFI system, it will be ignored. Was that command run from the chroot environment? We really need to know the preceding commands so we can spot any earlier errors that may have ocurred.

then

 grub-mkconfig -o /boot/grub/grub.cfg --target=x86_64-efi 

The --target= option isn't recognised by the grub-mkconfig script. And again, was that run from the chroot?

I essentially had issues where first my BIOS wasn't booting into the right partition (defaulting the to the windows partition which of course was also broken because of grub) after which we arrived at the point of this post

Can we also see

# parted --list
efibootmgr -v

^ Those commands can be run from any live environment, either use one with a graphical desktop for ease of posting or use a pastebin client.

Yes, I ran the commands from chroot. I'll get a live usb of another OS ready so I can run the commands and then upload the output to pastebin for you
