Bug Description

Apologies, this is a strange one and hard to describe...

Kaby Lake i7, 2 SSDs, windows 10 pro 1607 on NVMe SSD. UEFI/GPT all drives.

Ubuntu 16.04.2 _live desktop_ on SATA SSD. By that I mean live "CD" contents copied to a FAT32 partition. I use it that way since I use grub2 to launch other tools in the FAT32 partition in addition to Ubuntu. Acronis, for example.

If I boot _the same_ Ubuntu live version on a flash drive, I get the flash drive's grub menu and select "...try..." what actually boots is the live desktop on the SSD. I can tell since the flash drive shows up as removable and the SSD's partition is mounted as /cdrom.

If I obscure casper on the SSD ( casper->casper_OBSCURED) the flash drive live desktop gets booted fully. A persistence file on the SSD also will get used unless I obscure that.

If the live desktop versions are different, the flash drive desktop gets booted as expected.

I can also avoid the problem by booting a loop-mounted ISO of the live desktop on flash, even if it is the same version.
