What kind of shell ? grub shell, initramfs shell, emergency shell, login 
prompt ?

Is it the exact generated entry ?
What is the output of linux-boot-prober /dev/sda2 (or whatever the 
correct partition is) ?

Incomplete entries with root=/dev/sd* instead of root=UUID can be 
generated if /boot/grub/grub.cfg is missing in the foreign system. But 
/vmlinuz is usually a symlink and linux-boot-prober fallback script 
should ignore symlinks.

Is this the edited menu entry ?
