I would like to ask some questions again.
I tried once more again to set up things and i think that now I got what you told me
BT ~ # fdisk -l
Disk /dev/hda: 80.0 GB, 80026361856 bytes
255 heads, 63 sectors/track, 9729 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/hda1 * 1 8511 68359504+ 83 Linux
/dev/hda2 8511 9729 9788656+ 82 Linux swap
What about the id of hda1 and its boot flags. What kind of partition i have to create logical or primary?
