Windows 7 - Running windows 7 and want to install xp on external

Hey guy's/gal's well im trying to install xp on and external and runnning 7 now..
I found a sit that will help me with this Ngine.de - How to install and run a FULL Windows XP from a USB drive.


I'm having a problem with the sdk how do I get it to run i open the bin and the extracter and it flases the CMD and that's it is it not compadible with window's 7 please help me or direct me in the right direction if this guy is wrong..

Thank you,

Those are command line programs. That's why your getting a command window "flash'. You need to run them from a cmd prompt. Try running them in compatibility mode.

That being said, expand.exe (the extractor for those packed files) should already be part of Windows 7 as it came with XP. They might even have added a compressor but I'm not in the mood to dig around my system folder right now. If they are both there, you don't need the SDK.

7-Zip will also extract those types of files via a GUI.

Thank you dude I will try the 7zip way i have it allready and have been a user of it for while..
