How to make 3 partitons into one?

[g4mer]

I have 80GB HD with 3 small partitions, so i want to create one part from those 3.
I cant delete two partitions cuz one have system on it, and other has writen (boot) and i dont know what that means, but it just wont let me delete that partition. So is there any way to delete all those 3 partitions via BIOS or something cuz i know that windows wont let to delete him self (what a fag)

Open the Control Panel.
Open Administrative Tools.
Open Computer Management.
In the left pane, under Storage, open Disk Management.
The right pane should show a list of your drives, by letter, above a diagram of what partitions they have if any.

Obviously, you need to be an Administrator to perform this...

Empty the partitions, by copying the information to another of the partitions. When empty, use the above to delete the partition... Then clean up the resulting data...

If necessary, copy temporarily to a CD or DV drive or another drive on a USB enclosure.
