1. What are the terms dev/hda1, dev/hda2, dev/hda3, dev/hda 5 indicate in a Linux Boot Loader ?

2. Why the term dev/hda4 is not there ?

They are device names corresponding to various partitions on your hard disk

/dev/hda : Master boot record for your hard disk
/dev/hda1 : First primary partition on your hard disk.
/dev/hda2 : Second primary partition/Extended partition on your hard disk.

and so on ......

A hard disk can have a maximum of 4 primary partitions .... from hda1 to hda4 .... so these device names are reserved for primary/extended partitions.... however it is preferable to have hda2 onwards as extended partitions...

Since hda3, hda4 are reserved, so when you create logical partitions in an extended partition, their name is allocated from /dev/hda5 onwards....

Hope this much helps....

There can only be four primary partition on a disk the rest have to be logical partitions.
