The easiest and fastest no ******** route, is to use a windows 98 oem bootdisk from www.bootdisk.com
put a floppy in, execute the file, let it format the floppy and then write to you, boot from it run fdisk and then format it:
The Basics of Fdisk:
Primary partitions are the only one that are bootable. They're always the C: drive when active. Normally you can only have one (more with some special tricks etc.) Extended partitions are needed when you want more than one partition. You can only have ONE Extended partition. Logical Drives come into the Extended partition. They are handy since you know that you can only have one Primary and one Extended so you can get more than only two partitions. They would be your D:, E:, etc. drives.
First you need to reboot your system with the Boot Disk inserted.
1.At the A: prompt start "FDISK."
2.If asked to use Large Disc support say Yes.
3.The first screen looks like this:
Create Dos Partition or Logical Drive
Set Active Partition
Delete Partitions or Logical DOS Drives
Display Partition Information
Change current fixed drive. (In case you have two or more Hard Drivess)
So, to prepare you hopefully did a backup from your data. You did, didn't you ?!
4.Next we need to remove the existing partitions. So go to 3.
5.Next screen like this:
Delete Primary DOS
Delete Extended DOS
Delete Logical Drives
Delete always in the following order
Logical (All) > Extended > Primary (Last)
6.Go back to first screen after all partitions have been removed.
7.Now we need to setup our new partitions. Go to 1.
This screen looks like this:
Create Primary DOS
Create Extended DOS
Create Logical DOS Drives
Here we create in the following order
Primary > Extended > Logical Drives.
8.First create the Primary. If asked to use all space say No and enter the amount you wish for the C: drive. It should be set automatically to be the (only) Active partition. If not it may ask you or you have to select "2. Set active partition" from the main menu.
9.Next create the Extended Partition. Use all space left.
It probably advances automatically to the next step, creating the Logical DOS Drives.
10.Enter the amount you wish for the D: partition and than the rest for the third partition.
Think first about the size for the partitions.
OK now we're finished with FDISK so just exit it. Next you need to reboot with the disc still inserted and Format all partitions (the C: partition might need to be formatted with "format c: /s", check the Win95 tip). Another reboot and you can go ahead and install Windows.
