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. [...]

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:
sudo losetup -o $((2048*512)) /dev/loop1 hd.img
should'nt it be 63*512 ? Regards, Kamil Konieczny
