You can do it, but you must first check you BIOS to see of it allows you to boot from an external device. It must be usb. It will be slower and unreliable if there is ever a problem with your usb ports or the drive.

"It will be slower and unreliable"

To expand on the speed comment, consider the differences in theoretical data transfer rates:

USB 1.0 = 1.5 Mbit/s (0.19MB/s)
USB 1.1 = 12 Mbit/s (1.5MB/s)
USB 2.0 = 480 Mbit/s (60 MB/s)

ATA 100 = 800 Mbit/s (100 MB/s)

SATA 1 = 1200 Mbit/s (150 MB/s)
SATA 2 = 2400 Mbit/s (300 MB/s)

Real world transfer rates will be much slower. If you have an older motherboard that doesn't support USB 2.0, don't waste your time. It probably wouldn't support booting from a USB device anyway.

EDIT: after re-reading your question, I'm wondering what it is you want to do? Do you actually want to run Windows from an ext USB HDD or do you just want to install Windows to the ext HDD & then transfer it into a computer?

Hi dear Folks,
I want to run the WinXp OS from the external USB HD. My question is that
Is it going to be faster or slower?

I can't say it would be that much slower. The problem is that MS doesn't really want it's OS to be loaded on a usb device. There are hacks to get it to work.

Linux on the other hand works quite well on many usb devices.

Hi Dear Folks,
I still have one more question to ask you that should I still leave internal HD as master drive after establishing the external USB HD as Master drive in the CMOS setup?
Thanks for your important reply!

Installing an OS on an external drive is not supported by Microsoft. They will in fact tell you that isn't possible. In any event there are some serious issues involved. The legality of doing this is also questionable.

If you intend to move the external drive around to use it on multiple computers that probably won't work. The computers would need to be virtually identical or the computer won't boot to Windows. This is by Microsoft design.

Why do you want to do this?

Hi dear expert,
To tell to be honest, I am not going to use this USB HD in multiple computers. My Pc is already belongs to WinXP, and I just want to install Linux or Win2000 or WinXP ist edition in usb hd in order to run some other program.
Thanks for your important reply!

"WinXP ist edition" If you mean WinXP without any service packs there is NO advantage to running original. If the hard drive you attempt to install it on is larger than 127GB you will have problems. Even on an internal hard drive that holds true.

Any programs that run on WinXP original should also run on SP3. You should be running SP3 plus any further available updates.

If you want to run Linux from the external drive you should be able to do that.

Why can't you just run all those OSes from an internal hard drive/s? Partition the drive or run them in a virtual mode.
