Nonetheless, while the XP CD is bootable and you can run format from setup.
since you are unable to run setup, you will need to start with a Windows 9x
boot disk.
Boot with the 9x boot floppy. At the prompt, type fdisk and press enter,
delete the non-dos partition, create a primary dos partition, set it active
and exit.
If it says you have no non-dos partition your system is still fat32, delete
the primary DOS Partition, create a new one, set it active and exit fdisk,
reboot the system with the XP CD in the drive and run setup as follows:
A few screens into the boot process, if you see the message on the boot
screen to "Press any key in order to boot from the CD," do so.
After loading drivers and files, you should be taken to a screen with
the following:
To Setup Windows XP now, press ENTER.
To Repair a Windows XP Installation using Recovery Console press R.
To Quit setup without installing Windows XP, press F3.
In your case, press ENTER.
Agree to the License agreement by pressing F8.
You will then be taken to a screen with two options.
To repair the selected Windows XP installation press R.
To continue installing a fresh copy of Windows XP without repairing,
press ESC.
This will bring you to a partition map where you
can delete, create and format partitions.
Select the drive you wish to format, delete the partition, then create a new
partition, format as desired and continue with XP installation.
