I met it when I forgot to mount my partition. Did you pass the --root-directory argument to grub-install? Did you mount your / and /boot?

In this The above renewed emphasis is mine. > Could it be the case of https://savannah.gnu.org/bugs/?27720 or > http://grub.enbug.org/BIOSBugs ? I doubt this for the following reasons: 1. The BIOS boots with grub legacy, and an earlier version of GRUB2 as well. 2. Even the problematic version of GRUB2 goes into rescue mode. 3. The quoted reports talk about a BIOS that cannot do either of (1) or (2) and GRUB getting stuck at an even earlier stage. It may be a problem of the BIOS incorrectly identifying or being unable to load the additional (required) portions of stage2.

Bug#586735: grub-pc: external hdd boots on one system but not on the other
Package: grub-pc
Version: 1.98+20100617-1
Severity: important
Hello,
This is to report a regression from Version 1.98-1 which "Works For
Me". In order to help with the 'testing' of grub2 I recently installed
the newer version mentioned in the bug report.
I have grub2 installed to an external USB hard disk which is
formatted using GPT partition table. There is a separate BIOS boot
partition where I think grub is supposed to write its stage2.
The boot/root partition is inside an LVM partion.
The disk is recognised by linux on both systems as /dev/sdb.
On one laptop (IBM Thinkpad R51) the system boots normally.
On the other laptop (HCL Mileap based on Intel's old Classmate
design), grub goes into rescue mode with "no such disk" error. In this
state the disks and the partitions are recognised. However,
it does not recognise ext2 or lvm in this case. (I have a separate
ext2 partition on the disk which I attempted to use as root in
rescue mode but grub could not read the file system.)
I'm completely mystified and would be willing to experiment or
provide additional data in order to debug the problem.
Regards,
Kapil.
