Mam dwa dyski twarde. Pierwszy z nich zawiera zarówno instalacje Windows, jak i Ubuntu, ale pierwsze MBR uruchamia się w systemie Windows, a drugie MBR w teorii uruchamia się w Ubuntu. To działało dobrze do niedawna.
Zerowałem mój MBR na sdb, a następnie naprawiłem go za pomocą TestDisk. Wszystkie partycje i dane wyglądają dobrze. Po tym, podczas uruchamiania z sdb mam to na ekranie i nic więcej.
1234F:
Dotarłem do środowiska Ubuntu i uruchomiłem
sudo grub-install /dev/sdb
Brak zmiany. Pobiegłem
sudo grub-install --recheck /dev/sdb
Teraz przechodzi do ekranu, który mówi po prostu
GRUB _
i nie idzie dalej.
Pobiegłem ten skrypt informacji o rozruchu oto wyjście:
Boot Info Script 0.61 [1 April 2012]
============================= Boot Info Summary: ===============================
=> Windows is installed in the MBR of /dev/sda.

Zwracam uwagę na ten fragment:
=> Windows is installed in the MBR of /dev/sda.
=> Grub Legacy0.97 is installed in the MBR of /dev/sdb and looks at sector
74500216 on boot drive #1 for the stage2 file. A stage2 file is at this
location on /dev/sda. Stage2 looks on partition #5 for
/boot/grub/menu.lst..
Wygląda to dokładnie na poprawne, ładowanie z sdb powinno ładować root Ubuntu z sda5.
Więc GRUB jest zainstalowany i jest patrząc we właściwe miejsce, ale nic nie robi. Co może być nie tak? Dzięki.
menu.lstdogrub.cfgw / boot / grub?
