Grub2 automaticky nespouští..

[unus]

Mám v pc jeden SATA disk na kterém je nainstalován OS Ubuntu a po připojení SATA optické mechaniky mi přestal grub automaticky spouštěn OS. Musím stlačit klávesu ENTER aby došlo k bootu Ubuntu. Nevíte někdo co s tím?

[Krysař]

Otazka zni, na cem se to zastavi a co si zada potvrzeni Enterem?

Naběhne normální menu s výběrem jader. Jen není odpočítáván čas. Grub v pořádku naběhne jen automaticky nespustí žádné jádro..

Konfigurační soubor již není tak jednoznačný a umožňuje použít proměnné..

Zřejmě dojde z nějakého důvodu ke změně proměnné recordfail na 1, a pak to visí na nabídce. Možná řešení viz bug
