Comment 6 for bug 1901137

For me, it seems that the installer is ignoring my setting on where to install MBR (on the Something else... partition screen of the installer). I confirmed that the selected device both has an EFI partition, and that the EFI Partition has space (more than 200 MB). I am booting off external SD card reader, where I installed the Live Installer. Note the live installer EFI partition is only 5MB. I deselected the EFI partition from the liveinstall card ("Do not use this partition") and tried setting the "Install MBR to device" setting to both the internal SD disk device, and the specific partition. (If this isn't the same problem as here, recommend reopening 1902438)

I am able to mount and view the desired EFI Partition from the livesession.
