Brak Grub'a po instalacji Ubuntu

Post autor: bartex9 »

Witam,
Zainstalowałem Ubuntu 12.10 obok Windows 7 (osobne partycje). Cała instalacja przebiegła bezproblemowo, na końcu dostałem komunikat, że aby zacząć korzystanie trzeba uruchomić ponownie komputer. Niestety podczas bootowania włącza się boot manager z Windowsa, a nie Grub. W efekcie nie mogę się dostać do Ubuntu. Partycjonowanie wygląda tak:

Kod: Zaznacz cały

sda1  Windows Boot Manager
sda2  Windows 7
sda3
sda4
---sda5  /
---sda6  /home
W instalatorze wybrałem lokalizację Gruba na "/dev/sda". Co jest w takim razie nie tak? Jak mam rozwiązać ten problem?

Uruchom komputer z płyty instalacyjnej i podaj wynik boot_info_script.
