Po ostatniej aktualizacji włącza się tylko memtest.

[u-wlodek]

Witam!
Jestem totalnie zielony - proszę o wyrozumiałość.
Po ostatniej aktualizacji (mam 12.04) załącza się tylko memtest ja wciskam esc - restart i... "w koło macieju".
W GRUBie na ostatnim miejscu był winxp (domyślny - 5 sekund) ale teraz nic mi się nie pokazuje tylko wskakuje memtest.
Proszę o łopatologiczne porady. Zaczynam dopiero (na starość) przygodę z LInuksem. Pozdrawiam. WWlodek.

Obawiam się, że łopatologicznie za dużo tu pisania, a na google są gotowe poradniki.
Proponuję zainteresować się w tym przypadku kwestią przywracania Gruba 2 i wykonać czynności wedle jakiegoś, gotowego poradnika.

Coś mi się wydaje, że to nie brak GRUB-a jest tu problem, a brak kernela:

Przy braku GRUB-a, zamiast pętli z memtestem, pacjent widziałby grub rescue:>.

@u-wlodek,
masz dostęp do nośnika instalacyjnego Ubuntu 12.04 (płyta CD/DVD lub pamięć USB)? Jak tak, to odpal Ubuntu w trybie Live z tego nośnika, pobierz bootinfoscript, odpal go zgodnie ze wskazówkami podanymi na stronie projektu i jego wynik, wrzuć na forum pomiędzy znacznikami CODE.

[u-wlodek]

Zanim to zrobię doprecyzuję: Mam 1 dysk (ATA) podpięty jako master na pierwszym kanale IDE, na nim jest tylko Ubuntu 12.04 regularnie aktualizowane. Od czasu do czasu wkładam w kieszeń inny dysk z winxp (master na drugim IDE) i stąd w grubie na ostatniej pozycji pojawiła się opcja uruchomienia windy (domyślnie, dla żony aby się nie irytowała). Po każdej poważnej aktualizacji pojawiał się na drugim (może 3) wybór poprzedniej wersji systemu a domyślny xpek przesuwał się o jedno oczko niżej do czasu posprzątania systemu. Ale do tej pory wskazany w ten idiotyczny sposób memtest się sam nie uruchamiał.
