I am trying to use grub2 on a USB stick. My situation is: - I'm using RHEL4 which has grub 0.95 installed on the system, and creating another OS in a directory to install onto a USB stick, and I want to use grub2 on that USB stick (but not on the host system). - I compile grub 1.98 with --prefix=~/grub - The root of my target system is ~/fsimage. I added a ~/fsimage/boot/grub/grub.cfg and ~/fsimage/boot/grub/device.map which contains "(hd0) /dev/sdc" where /dev/sdc is my USB stick. - I use genext2fs to create an ext2 image from ~/fsimage, and cat that to /dev/sdc1 - Run ~/grub/sbin/grub-install --no-floppy --root-directory=~/fsimage /dev/sdc
Based on this use case: http://grub.enbug.org/UseCases/Ubuntu But I get an error: ~/grub/sbin/grub-probe: error: cannot find a GRUB drive for /dev/sda1. Check your device.map. Auto-detection of a filesystem module failed. Please specify the module with the option '--modules' explicitly. Is there a way to get this to work? We had this working with grub 0.95 by using: echo -e "root (hd0,0)\\nsetup (hd0)\\nquit" | /sbin/grub --no-config-file --batch --no-floppy --device-map=<(echo "(hd0) /dev/sdc") But I'd like to switch it to grub2 if possible..
