Follow-up Comment #4, bug #42029 (project grub):
Thanks about biosnum.
I tried to set biosnum like below, but no success :-(
In reference, https://www.gnu.org/software/grub/manual/html_node/biosnum.html
>When chain-loading another boot loader (see Chain-loading),
>GRUB may need to know what BIOS drive number corresponds to
>the root device (see root) so that it can set up registers properly.
So I searched "BIOS drive number" and got pages below.
http://stackoverflow.com/questions/11174399/pc-boot-dl-register-and-drive-number
I tried following sequence where XXXX=0x80, 0x81, 128, 129, 130, 0, 1, 2, but
failed to boot.
(0x81, 129 gives no error display and halt, other gives "boot error".)
grub> nativedisk
error: no device connected.
error: disk `hd0,gpt1' not found.
error: disk `hd0,gpt1' not found.
grub> ls
(ahci3) (ahci2) (ahci1) (ahci0) (ahci0,msdos1) (ata0) (ata0,gpt3)
(ata0,gpt2) (ata0,gpt1) (ata2)
grub> set root=ahci0,msdos1
grub> set biosnum=XXXX
grub> chainloader +1
grub> boot
