Po instalaci Ubuntu 10.04. 64 bit se provedla aktualizace a od te doby nelze nabootovat.
Po restartu nabehne jen konzole grubu
takze mam jen grub>
abych mohl nabootovat tak musim zadat
root (hd0,5)
configfile (hd0,5)/boot/grub/grub.cfg
kdyz tohle udelam nekolikrat tak se mi casem objevi nabidka s vyberem operacnich systemu a ubuntu normalne nabehne
jak to opravit, aby se ta nabidka objevila automaticky?
je divny, ze ve vysledcich ze skriptu boot-info neni u jednotlivych souboru uvedena velikost, ale jen otazniky, tak jestli to neni nejaky komnuty
