On both of my computers, I am unable to run the installer. I followed precisely the instructions [here](https://pureos.net/download/) and created the install drive with etcher. After selecting the first menu entry
> PureOS Live [EFI/GRUB]
grub prints out:
> error: no suitable video mode found.
> Booting in blind mode
When setting gfxterm as terminal output it works again. I added those lines in the boot entry before loading the linux kernel:
> insmod efi_gop
> insmod efi_uga
> insmod font
> insmod gfxterm
> set gfxmode=auto
> set gfxpayload=keep
> terminal_output gfxterm
These lines need to be added to grub.cfg
