Basically, everything as far as i can see. After completing this tutorial, your Windows XP install should directly boot off your USB-drive, and be fully upgradable, DirectX games will run, all apps i tested work like normal, speed is the same as with a real HDD (you need USB2 though) - so it is in fact a fine solution as far as i can see.

Requirements
An existing Windows install for carrying out the steps in this tutorial
A USB2-compliant Hard disk drive (or a big USB2 stick, see remarks below)
An original Windows XP CD (tested only against SP1 so far, but reported to work on other versions)
A registered version of WinISO (or any other software that allows direct editing of ISO files)
The Microsoft CAB SDK
A CD-burning software that can handle ISO files. I like the free burnatonce
How To:
Summary:
We will dump the contents of your original Windows XP CD , extract a few files from the Image using ISO modification software, edit the files, and put the modified versions back on the ISO. The resulting ISO image is burnt back onto a CD media, and can then directly be used to install Windows on your USB drive.
I am also covering a few pitfalls that happened to me, in hope they will save you a bit of time.
1) Does your computer support booting from USB?
Usually, if its an option in your BIOS boot sequence menu, the answer to this is yes. If its not there, look for BIOS updates. If you are not sure, proceed and see what happens
2) Sorting out the "Bootability" of your USB-Drive
Connect your USB drive to your computer, directly, without a Hub. Then, shut down your computer, disconnect any other hard disk drives from it, and insert your original Windows XP CD into the drive. Start the installation, and proceed to the section where you are allowed to pick a hard drive. If it goes beyond the partition selection, your drive is already fine for booting Windows XP. If not (seems to be the cases with many of the Freecom USB HDDs for example), you will get an error like "Windows is unable to find your drive, partition, data etc bla". This is usually not a big problem. All you need to do is "properly" format the drive. Reboot into your normal Windows, and get this HP tool , and use it to format your HDD completely. I chose NTFS format, worked fine everytime i tried. After this, my drives are recognized as valid installation devices by the Windows XP installer.
(In fact, i did not manage to create a USB primary partition with FAT32 that was recognized as being installable)
3) Dumping the original Windows CD into an ISO File
Pretty easy one. Simply open WinISO, and select Actions -> Make ISO from CDROM, and save your CD image.
4) Extracting the files we need to work on
After the CD dump is done, close and reopen WinISO. Then, open the ISO file you just created using File -> Open.
Now, click the I386 folder, and select the following files (Ctrl key to multi-select)
TXTSETUP.SIF
DOSNET.INF
USB.IN_
USBPORT.IN_
USBSTOR.IN_
Select Actions -> Extract and put the resulting files into some folder to work on them.
5) Unpacking IN_ files
Use the Cab SDK (from the command line) for extracting the contents of the .IN_ files. Each of them contains exactly one .inf file. If you are unsure how to use the Cab SDK, here is an example command line: "cabarc x USBSTOR.IN_" . You should end up with three new files in the folder, called:
usb.inf
usbport.inf
usbstor.inf
You can now delete the .IN_ files.
6) Editing the files
This is the main job. i ll also try to explain a bit whats happening. Use a simple Texteditor like Notepad.
6-A) TXTSETUP.SIF
This file is loaded on the initial install step by the Windows XP CD installer. In this file, we will change the way Windows treats USB devices during system setup -- the default is to only treat them as input devices during installation -- we will change this to include mass storage driver support (which needs to be loaded into the installer much earlier in order to work).
First, move the following entries from [InputDevicesSupport.Load] to the [BootBusExtenders.Load] section , as shown here
Next, we also have to write several keys into the registry. Convieniently, the txtsetup.sif allows you to specify files that are parsed and instered into the registry at install time. Insert the following in the [HiveInfs.Fresh] section:
HKLM,"SYSTEM\CurrentControlSet\Services\usbohci"," DisplayName",0x00000000,"Microsoft USB Open Host Controller Miniport Driver"
HKLM,"SYSTEM\CurrentControlSet\Services\usbohci"," ErrorControl",0x00010001,1
HKLM,"SYSTEM\CurrentControlSet\Services\usbohci"," Group",0x00000000,"System Reserved"
HKLM,"SYSTEM\CurrentControlSet\Services\usbohci"," ImagePath",0x00020000,"system32\DRIVERS\usbohci.sy s"
HKLM,"SYSTEM\CurrentControlSet\Services\usbohci"," Start",0x00010001,0
HKLM,"SYSTEM\CurrentControlSet\Services\usbohci"," Type",0x00010001,1
7) Repack the inf files into their original IN_ format
If you have not already deleted your extracted .IN_ files, do so now. They need to be replaced. Open a DOS shell again, and navigate to the folder with your changed files. Then exceute the following commands:
cabarc n USB.IN_ usb.inf
cabarc n USBPORT.IN_ usbport.inf
cabarc n USBSTOR.IN_ usbstor.inf
The three IN_ files should now exist again.
Congratulations. All out modifications are done.
Inject the changed files into the ISO
Open your Windows CD image again with WinISO. Navigate to the I386 folder, and delete the following files from the ISO, saving the changes to the ISO afterwards:
DOSNET.INF
TXTSETUP.SIF
USB.IN_
USBPORT.IN_
USBSTOR.IN_
Just to be sure all is updated in the ISO, cloase and repoen the ISO in WinISO. Now, again go to the I386 folder and select "Add Files". Now add your changed files, in detail:
USBBOOT.INF
DOSNET.INF
TXTSETUP.SIF
USB.IN_
USBPORT.IN_
USBSTOR.IN_
Save the ISO. You are done.
9) Burn the ISO back to CD
Feel free to use any burning package you want. I used the free and simple Burnatonce
10) Install Windows XP from the CD
Shut down your computer. Disconnect ANY internal and external hard drives (so Windows cannot find them during installation and mess up their Master Boot Records hehe). Some computers will have trouble to boot without an internal HDD attached, check in your BIOS and, if possible, remove the HDD from the boot sequence and set the USB Harddisk as the first boot device, and the CDROM as second.
Also, now connect your USB Harddrive directly to the computer, without any Hubs in between.
Windows should install just fine, with the exceptions noted below.
Issues you will encounter during installation:
During driver installation, the USB drivers will prompt you, as they are "not certified" - This is normal. Our changes invalidated the checksum, and therefore the driver is no longer signed. Just press "yes" a couple of times.
Upon completion of the install, the system will complain once on the first bootup that the pagefile does not exist. You can ignore this for now, as Windows will work fine without it. People are looking at fixing this issue, but its not critical for now.
Once everything is up and running , shut down and reconnect all your drives.
^^If your PC/Laptop comes with Windows 6 (AKA Windows Vista) or Linux 2.6 (AKA 99.99% of all distros Distros)or FreeDOS, you might want to see how XP feels like on the machine without messing with MBR.
But one major flaw XP has is that its hardware locked on installation. You need to crack it so that it does not refuse to boot due to change of hardware when you insert the USB device into another machine and boot.
