Grub na jiné místo?

[vlasto]

Mám problém a nevím co s tím.Mám na jednom disku dvakrát Ubuntu.Jedno má grub hd 1,0 a druhé 1,2.Od začátku to zlobí a potřebuji to dát do pořádku.Když jsem  provedu aktualizace např.jádra ,tak to do Grub.menu.lst nezapíše .Mám pocit,že to je tím,že jsou Gruby na jiném umístění.Mohu dát dva Gruby od rozdílné instalace  na stejné umístění?

[Milhouse]

V /boot/grub/menu.lst přidejte záznam o tom 2. Ubuntu tak, aby ukazoval na oddíl 1,2. Jinak to bude stejný. Teda kromě UUID.

Když sem dodáte oba výpisy, dokutíme to dohromady...
