TGL-UP3
CID: 202104-28962
BIOS: TGLIFU1.R00.4304.A01.2107290604

To install a new image, I need to boot Ubuntu from a USB drive, wipe out the device's internal storage, and copy the new image over to it.

I have used the same USB drive to do this countless times - including on this TGL-UP3 to install Ubuntu Core.

However, now that it's been reflashed, I can't. If I go into the Boot manager in the BIOS and select the USB drive, it just goes to a GRUB prompt instead of actually booting.

I tried resetting the BIOS to default settings within the BIOS but it still just boots to GRUB when I try the USB drive.
