Windows is not opening

[Battal Gazi]

Don't think you can, as said below.

Only way I think you can is if you copied an image of your previous drive.

You mean that i should install to normal drive, then copy or move this windows files to external drive?

In otherwords, you can NOT INSTALL windows on an external.

But bios has a option of boot from usb-hdd?And alos zip flash etc?

What I meant is to install it to the normal drive yes, but you can't just copy the files. You can however use 3rd party software to make an image and copy it to the external.

Edit:

A collection of limitations (both hardware and software) currently prevent Windows from booting and running off a USB drive. Some of them are described in this whitepaper from WinHEC 2003. Another reason not mentioned in this paper is that during any hot-plug operation, the USB bus is completely reinitialized. Windows really doesn't like it when it loses access to its boot device. Imagine, you plug in a USB camera, the USB bus reinitializes, Windows loses access to the boot drive, and *oops* the kernel needs to page in some data and it can't.

Edit 2: I also read it's possible but I won't really count on it.

Battal, It has a boot option because you "CAN" boot from it, but you "CANNOT" install it from the CD as you normally would.

Jo has a soultion, read it thoroughly.

Just wipe one of the Hard Drives and reinstall. Get it? Got it? Good!

The boot from USB option allows you to use a flash drive as a boot device, not as a main drive. For example, I used a flash drive to install Windows 7 beta on my computer because my optical drive had died at the time.

I never knew you could do that... Nice one, Trotter!
