I see. Well, I've never installed W4 without having floppies so that I do not have experience with making a bootable installation CD for it. But, perhaps, someone around can be more experienced. The task is: Make a bootable ISO, which can be used for installing W4 from scratch - not a maintenance CD but an installation CD.
In the meantime, you can use a more complicated way for smuggling W4 on your machine. You will need:
(1) Another comp, where you can install W4 temporarily.
(2) Download PING from
http://ping.windowsdream.com/ PING is a Linux partition backup/restore which knows HPFS so that you will be able to port an image of a W4 installation from "another comp" to your machine. One of the PING files is a bootable ISO of PING. PING is a freeware. Prepare a CD.
(3) Download DFsee from
http://www.dfsee.com/ DFsee is a HD editor, FDISK, etc. DFsee is paid but it has an enough long free evaluation period. Download DFsee bootable ISO, do not burn right now

wait until you'll be ready.
(4) Have a transport media (USB stick, CD, 250 MB Zip, etc.) which can hold ca 230 MB data ready.
(5) Install "bare bones of W4" on the "another comp". Do not install anything that you can install later from the installed system. Install with generic VGA, patch HD driver with Daniela's one.
(6) Boot from PING CD and backup the partition. The backup will be ca 230 MB, PING stores only used sectors and bzips them.
(7) Make a partition on your comp without floppies using DFsee. The partition should be of the same size as the partition where you have installed W4.
(

Boot your comp with PING CD and copy the partition with W4 to your comp.
(9) Boot your comp with DFsee and "accomodate" the copied partition on your HD. Note that "another comp" had anoher HD with another sectors/track, etc.
(10) Boot from your HD. W4 should start. Finish the installation.
(11) PING once more: backup the final installation from your comp and save the image for later use. You can study PING deeper now

It allows you, among others, to create a bootable ISO which will contain the partition image and which will install it after booting. The ISO can also create the partition when needed. I have no experience with it but it should be possible.
Uffff ... A bit complicated but it works. I have installed eCS this way until eCS was able to boot from a USB CD. I wasn't able to install, either, and this was the only way of installing.
