I have a Dell XPS with multiple drives, one for each OS.  I can boot Ubuntu 16.04 fine with the G4D code:


Kernel /vmlinuz root=/dev/sda1 ro

initrd /initrd.img"

I get no errors


With Ubuntu 18.04, I use:


kernel /vmlinuz root=/dev/sdb1 ro

initrd /initrd.img"


I get a error 13 after the UUID line.  It says "Booting Ubuntu 18.04.2 LTS (sdb1).  Setting root to (hd1,0). Filetype is ext2fs, partition type 0x83" and stops with error 13.



I've always used G4D quite successfully until Ubuntu 18.04.  18.04 boots okay under native Grub2.  I'm  very confused.  I might point out that the 16.04 drive is a Toshiba 500GB and the 18.04 is a WDC 500GB.  Any help will be appresiated!

Are these internal drives or USB drives?

What do you see if you try each of the commands from the command line?

Is it the kernel line that is failing? grub4dos usually reports the failing line.


blocklist /vmlinuz

before the kernel command
