[How to install Windows from USB- WinSetupFromUSB with GUI]

Then you have some other problem.

When exactly and what error code?

The easiest thing would be to start from a scratch. Reformat the USB disk and prepare it again. Replace the files and lines mentioned. Report what errors do you see and when exactly.

I am thinking that BIOS sees the USB disk as a superfloppy/zip disk, hence the problems. But let's first rule out any interventions.

What hardware are you installing to? Motherboard or laptop model? Using what USB disk?

I've gotten Error 11 on second time with a different hdd plugged in. The first time, I booted it up to test the program, I seen XP install blue screen, so I was like ok, it works, I shutdown, removed two hdds and plugged in the one hdd I wanted XP on, this is when Error 11 took place.

After editing everything then I got Error 15 even just with the hdd I wanted xp on, plugged in.

(A). I started a fresh day restarting from scratch, unplugged everything except the hdd I installed too and the USB card reader too SDHC Class 6 flash card.

2006 mobo.

With the procedure (A), I've managed to get XP installed on too my hdd.

Suppose the program will have to be redone for every new install of xp.

Thanks, ilko_t for the help .

For everyone using 1.0 beta7 version of the program and already put Windows 2000, XP, or 2003 source(s) on USB disk- a quick bug fix before the next version is ready.

There are a few lines in winsetup.lst to be edited to avoid possible "I/O error...." errors at the very beginning of Text mode.

The error would come up only if you previously started one of your Windows 2000/XP/2003 setup sources on computer with 2 or more internal hard disks and use the same setup source on a computer with different number of internal disks.

This happens because BootDevice and SetupSourceDevice values in TXTSETUP.SIF in the small ISO file got permanently changed to new rdisk(X) values, thus consequent search for rdisk(1) & replace with rdisk(Y) will fail as rdisk(1) has been set to other value, according to the number of the hard drives connected in the previous boot of this menu entry. In other words- Setup will be searching for its files in the wrong disk and will throw an error that the disk is not accessible.

Edit in root of the USB disk winsetup.lst in Notepad and change the line:

map /WINSETUP/_ISO_FILENAME (0xff) || map --mem /WINSETUP/_ISO_FILENAME (0xff)

where _ISO_FILENAME will vary according to your source, to:

map --mem /WINSETUP/_ISO_FILENAME (0xff)
map --e820cycles=3

Also replace GRLDR file in root with the one in this archive:

http://grub4dos-chenall.googlecode.com/files/grub4dos-0.4.5b-2011-12-30.7z

You need only the GRLDR file from the archive.

If you already are experiencing the "I/O error", you may recreate the USB disk, or edit TXTSETUP.SIF in all present small ISO files in WINSETUP folder using UltraISO or a similar program and change all occurrences in SetupData section from rdisk(X) to rdisk(1) where X will vary. Next change the above mentioned lines in winsetup.lst to avoid further issues of this sort.

None of this works for me.

I've tried 5 programs to get xp on usb. They all don't work including this one. Why is there such a large volume of problems with xp on usb. MS made one that works for win7 that works 100%, unetbootin works 100% with linux distros. What is the deal with XP on USB that is so dam troublesome? Can I get an amen?

Anyways, how can I get this program to work?

I get I/o errors, I did the edit thing, then I get couple other errors with numbers like Error 11, (I just got error 15 right after I replaced GRLDR with recommended GRLDR in the zip.)

I am so frustrated, I've been on this mission for 15 hours. I'd use a cd rom drive but I dont have one and cannot get one.
