no asi nemáš vytvořenej /boot/grub/grub.cfg či /boot/grub/menu.lst

grub.cfg u mne :
set default=1
set timeout=2
set root=(hd0,6)
if font /usr/share/grub/ascii.pff ; then
  set gfxmode=800x600
  set gfxpayload=keep
  insmod gfxterm
  insmod vbe
  terminal gfxterm

místo root=UUID můžeš dát root=/dev/hda* nebo root=/dev/sda* podle tebe , samozřejmě musíš vědět co kde máš a upravit jinak ti můj fungovat nebude.

Takže neni chyba co ti to dělá , jen nemáš konfigurační soubor.

[pepe_]

a nastartovat můžeš :

například u mne :


grub> root (hd0,4)
 Filesystem type is ext2fs, partition type 0x83




hledáš až najdeš správnou partition která nehlásí  Filesystem type unknown


potom

kernel (hd0,4)/boot/vmlin


a zmáčkneš tab (vybereš správnej) a enter

potom

kernel (hd0,4)/boot/initr

a podobně jako s kernelem

a nakonec   boot a enter






pokud chceš bootnout například winxp na první partition tak

root noverify (hd0,0)
makeactive
chainloader +1
boot



doufam že ti to pomůže

hm divne, konfigy existuju, nefunguje mi to len s grub vo verzii 0.97-29ubuntu59 ani nenabootuje, stale ta hlaska co predtym, dokonca je opatchovany tento grub, aby spoznal btrfs system, samozrejme /boot partition mam na ext4. Skusil som grub2 vo verzii 1.97~beta4-1ubuntu4.1 ten nabootuje, ale nejak nevie spoznat /root partition. Skusil som ju prekonvertovat spat na ext4 ale stale je niekde problem, s grub.cfg sa mi zda ze berie stale zle UUID disku, pritom v /etc/fstab je zmenene OK, len v grub.cfg neviem zapisovat aby som to rucne zmenil.
