I encounter a problem when making a bootable disk image because GRUB
always enters a
rescue shell.

I want to create a disk image and install GRUB 2 on it and then use
Bochs to run it. The steps are as follows.
[...]

Bochs BIOS - build: 02/16/17
ata0 master: Generic 1234 ATA-6 Hard-Disk (  49 MBytes)
Press F12 for boot menu.
Booting from Hard Disk...
.
error: no such device: c5b2c483-70c2-4212-840b-da5f965d0555.
error: unknown filesystem.

Looks like that blkid 'c5b2c483...' is not valid for your boot device,
see command:
blkid

also:
lsblk

or search with google: grub2 without uuid

or discover what uuid your partition will have (or assign it)
or turn to some grub2 guru/forum for help

or it may be problem with disk configuration, like loop1 is using
linear mode, and bochs uses incompatible one (? i am not sure here)
then bios geometry is mixing up sectors sequence

or in step 3:

quoted

sudo losetup -o $((2048*512)) /dev/loop1 hd.img

should'nt it be 63*512 ?

nope should be 2048 and this is why -->
