I'm trying to install Ubuntu on my harddisk which doesn't contain any operating system, MBR or Grub. It has 3 partitions, 1st includes my data on NTFS file system, second is Linux swap now, and third ext4 filesystem.
Of course I don't want to lose my data on the NTFS partition. Anyway, I installed Ubuntu on ext4 filesystem, selected sda as device for bootloader (not sda1,2 or 2). But i got the error
Error:unknown filesystem Grub rescue >
ls. It gives (hd0) , (hd,msdos1), (hd0,msdos2) and (hd0,msdos3).
then I tried
ls (hd0,msdos3)/ to find the Linux filesystem to boot. But I was unsuccessful. It all gave me
unknown filesystem error. Am I missing something?
