Hi,

I have installed Fedora 13 on an external USB 1TByte harddisk and wanted to integrate it into grub2 on my notebook.

Unfortunately, I can't start F13 from grub2 boot-menue.
I get an error on UUID "e87da235-0c58-4e83-a8c8-aab9bf994285".

I have attached the /boot/grub/grub.cfg from my debian/sid system.
Also, the /boot/grub/menu.lst and /boot/grub/device.map from the F13 system.
FYI: Fedora uses still a patched grub-legacy ("grub1") as default.

The funny thing is:
Installing F13's grub1 to USB-hdd's MBR gives a "geom error" back.
Might be a "distro flamewar feature" :-).

Kind Regards,
- Sedat -

menu.lst is a symlink on f13 to ./grub.conf.
Dunno what's wrong with sending it... so I just cut-n-paste.

Here is the section concerning F13 in debian's grub2 config:

# grep -A10 -i fedora /boot/grub/grub.cfg
menuentry "Fedora (2.6.33.3-85.fc13.i686.PAE) (on /dev/sdb7)" {
	insmod part_msdos
	insmod ext2
	set root='(hd1,msdos7)'
	search --no-floppy --fs-uuid --set e87da235-0c58-4e83-a8c8-aab9bf994285
	linux /boot/vmlinuz-2.6.33.3-85.fc13.i686.PAE ro
root=UUID=e87da235-0c58-4e83-a8c8-aab9bf994285 rd_NO_LUKS rd_NO_LVM

KEYTABLE=de-latin1-nodeadkeys rhgb quiet
	initrd /boot/initramfs-2.6.33.3-85.fc13.i686.PAE.img
}
### END /etc/grub.d/30_os-prober ###

### BEGIN /etc/grub.d/40_custom ###

That looks very sane to me.

BTW, the exact error when selecting F13 from grub2 boot-menue:

error: no such device: e87da235-0c58-4e83-a8c8-aab9bf994285

Hi,

Changelog in [1] says:
"- Add support for initrd images on Fedora 13."

So, I give new grub2 package a next try.

Unfortunaley, I still can't boot F13 from Debian's grub2-boot-menue.
These are the error-messages (Line #2 and #3 are new):

error: no such device: e87da235-0c58-4e83-a8c8-aab9bf994285.
error: no such disk.
error: you need to load the kernel first.

[ /boot/grub/grub.cfg ]
OLD: set root='(hd1,msdos7)'
NEW: set root='(/dev/sdb,msdos7)'

I am also adding the new generated grub.cfg file.
