install: Look for grub2 files on the initramfs, not rootfs
Fixes [YOCTO #3870] atom-pc - cannot boot image on netbook after install The problem here is that grub2 is installed but a grub 1 menu.lst is created at install time. At boot, grub2 doesn't find a grub.cfg file and drops to the grub shell. This happens because the installer is looking for 40_custom (a grub2 file) on the rootfs, but grub2 isn't installed on the rootfs. It exists in the initramfs. Patching the installer to look on the initramfs resolves the problem. Note that the problem may have occurred if grub2 used to be installed on the rootfs but was later removed. In any case, the installer is HORRIBLE and really needs to be completely redesigned as part of the deployment effort. For now, this should get the live image installer limping along again. Tested on a Toshiba NB-305. (From OE-Core rev: d961e42674bf929adfff391c6f3f284a7e7b0d95) Signed-off-by: Darren Hart <> Cc: Cc: Cc: Cc: Signed-off-by: Richard Purdie <>
