I am going to buy the Fujitsu-siemens Esprimo Mobile V6505 with dual-boot. Given that I can either have the XP or Vista, as its not dual boot, I am thinking of keeping it in Vista. I have the HDD from my previous Toshiba A100 laptop with XP Pro loaded on it. Laptop died and I rescued the hard disk alone. I was wondering if I could connect this rescued HDD via USB to the Fujitsu-siemens laptop and boot XP via the USB. Is this possible? I don't want to give up XP and I would like to run few existing programs using my XP. Can anyone help me with this? If it wont work on the Fujitsu-siemens laptop, then is there another laptop I could by to do this? Thanks in advance,

It has been done. I suspect it won't be worth your trouble. Main problem is the way the XP was installed. If OEM then it is tied to hardware. There are a few ways to convet it and run it as a VM but we go back to not worth the time and trouble (since you asked). "Best Practices", Event viewer, host file, perfmon, antivirus, anti-spyware, Live CD's, backups, are in my top 10

Can I then install XP SP2 on a pen drive using another laptop and then use it on the Fujistu laptop? Or can I make the new Fujistu laptop into XP and then run Vista on USB (if I can install Vista on USB?) The reason I want 2 separate boots are: 1. I don't want to do a dual-boot on the same HDD as it looks complex. 2. I was hoping that I could use the spare HDD I have to run a different OS. Thanks in advance

You maybe be much better off installing Virtual PC or Virtualbox. Both are free and easy. They are software versions of real computers. They look like any other Windows application and can do almost everything a real computer can. MS products have been produced to NOT run on usb for the most part. Linux. Solaris and BSD based OS's seem to do fine in many cases. "Best Practices", Event viewer, host file, perfmon, antivirus, anti-spyware, Live CD's, backups, are in my top 10

Thanks very much.
