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 ?
nope should be 2048 and this is why --> https://superuser.com/questions/352572/why-does-the-partition-start-on-sector-2048-instead-of-63
