Welcome to the forums @eggiej
That error usually comes down to how GRUB is being installed on eMMC (mmcblk). So Make sure you booted the USB in UEFI mode, not legacy. Also check that there’s an EFI partition (FAT32, mounted at /boot/efi).
In the installer, try setting the bootloader target to the whole disk like /dev/mmcblk0 instead of a partition.
If Windows installs fine, it’s likely already using UEFI, so Mint should match that.
eMMC systems can be a bit picky but it’s usually something small.
Also don’t forget to check Linux Mint forums:
