set root=(hd0,msdos1)

will often do the thing, may need to change the numbers.  These are
often hidden inside a
grub2 find statement.
This sets the boot partition, and names used in the "linux" kernel;
specification are given
in realation to this root.

Then in the "linux" kernel line, the root=/dev/sd?? is used to set the
system root.

    linux vmlinxuz-<whatever> ro root=/dev/sda3 [<options>]*
