Hey I am new here, but I am very much impress...

I have an question I bought external drive I want to install Window OS on it and some software because I want to use my external drive where I want to sit. I mean when I attach my external hard drive to another computer and start computer I have to choose the option and boot from my external hard drive in this way I can werk on my external hard drive without bothering anybody PC and if is working then is easy to travel with my external hard drive so anybody have solution of this or good tips then send me an e-mail I will really appreciate

1. Insert the windows OS disc

2. Plug in your external hard drive

2. Change the boot sequence, to boot from CD/DVD-ROM

3. Select the correct hard drive, NB make sure that it is the correct hard drive

4. Start installing the OS...

If anyone has a better suggestion follow their procedure!

It won't work. Windows NEEDS to be on a C:\. Also every time you'll plug it in to a diff computer the hardware would be different. Plus you'd never get an IP assigned to you so no internet or network resources. It's a good thing that this won't work because it would be a small for network admins.

Some versions of Windows (XP for example) do not need to be on the C drive. However, not all PCs or external drives can be setup as bootable from the external drive. You also have the hardware issue that Need mentioned.

I would suggest getting a laptop rather than this scheme.

Have a read at this url,from Microsoft.It is a very long-winded read,but maybe it might help:

From a personal view point,installing XP,or Vista,on a USB Pen/External drive,and carrying it around,and pluging it in to a terminal of your choice (family,friend,college,work) is a recipe for disaster.Even if it worked?-two versions of Windows,on one machine... (licence,ethics,etc,not withstanding),what if your USB Windows,had a corrupt file,and messed up someone else's system.I would be gutted.Also,what Need,and Scott have said,is correct.
