Har precis installerat Ubuntu 10.04 (första gången jag testar något Linux-OS) och Ubuntu funkar finfint. Dock får jag inte upp något alternativ för vilket OS jag vill boota till vid omstart. Jag trodde jag gjorde rätt för att få dual-boot vid installation (men så är tydligen inte fallet).
Så här såg det ut innan jag installerade Ubuntu:
Dator med 2 hårddiskar. Windows Vista installerad på den ena (c:\). Den andra (d:\) används bara som lagring.
Jag delade på d:\ i två partitioner och tänkte installera Ubuntu på den ena av dessa. Vid installationen måste jag ha knasat till det med hur den disken skall partitioneras för efter installationen av Ubuntu har jag nu 3 partitioner på denna disk.
Sedan kan jag inte boota till Windows längre. Jag får inte upp något alternativ för att välja OS. Om jag kollar i grub.cfg finns inte windows med som ett alternativ.
Min grub.cfg:
