Onwards....

We was talking about FDISK.
Yes, the spiel has begun...

YOU TOOK THOSE NOTES? I hope you did...

You checked, and know which drive you want to partition, right?
You have started fdisk from REAL MODE DOS, and selected the drive you want...
(Drive 1 is default, it may NOT be the one windows is on, since windows will be on/(go onto) the first ACTIVE partition.)

You should ALWAYS look which partitions you have, which letters a DRIVE has on it, and which partition shows an A in it (A for active, under status.)
IF it shows a NON DOS partition, the drive may have overlay, linux, or NT (see further in thread).
You ought to know... If you do not know why that NON DOS partition is there, you will have to find out.
There is INFO about recognising what some partitions are FOR later in the thread.

By the way, you should take notes on the way you set it up.
WHY? When you write down percentages or sizes you typed into the menus, you stand a far better chance of rescuing data at a later date...
I say at a later date, because of Murphy's law.

onwards;

REMEMBER that if a non dos partition exists and is active, you most likely DO NOT want to mess with it with FDISK.
If the non-DOS is NOT active, and you want to repartition, you may have to activate the non-DOS to be able to remove another partition, and later on choose primary dos as active.
You do NOT want to leave the NON-DOS active if it wasn't
I ask to look into all this because you cannot delete an active partition while there are other partitions still present on this drive.
You'll also find that you cannot delete a primary partition while an extended partition still exists on the drive.

The following is menu stuff,
Since this is just an example to show you what to look out for, you should use your head, and not always blindly follow these steps.

If you need delete partitions
Option 3
From the highest letter we work down to C:
For instance
E: (if it isn't active drive)
esc
3
Delete logical drive D: (if it isn't active drive)
esc
3
Delete extended partition
esc
3
Delete primary DOS partition
esc
esc
Do a cold boot (It's quite important you reboot.)

Again fire up fdisk
y
--(if needed, first select drive)--
4
(it shows you have no partitions? good! If a NON-DOS exists and you know why it is there, don't wipe it)
esc
1
Make primary DOS partition.
Well, here is where you decide how you set it up.
I would say "dont let it use all space" because an extra partition is great to put data and installable files on.
So, don't let it use all space. (And write down what you entered there... percent or size.)
Then, create extended partition. (Let it use the rest.)
It will say there are no logicals defined.
Make them. (Select the the sizes you want, or let it use all space, and write down what you entered.)

* If you had to make NON DOS active to remove PRI-DOS, this is the point you make PRI-DOS active *

When you are finished with partitioning
esc
esc
And again do a cold boot
