Hi,

I have read a writer said:

He wants a tutorial for how to go about installing and running Windows 7 on an external drive as I have been trying to do this when a friend's laptop hdd controller failed. 'Very nice tutorial but I'm afraid would not be applicable to my friend's laptop since the hdd controller is broken, the host system where VMware will be installed should ran from the external hdd which I'm afraid is almost impossible in Windows 7. Anyway, the tutorial gave me lots of ideas to solve a friend's problem. Thanks again!"

I got confused that why installing and running Windows 7 on an external drive not be applicable to his friend's laptop since the hdd controller is broken?

He wants to install the Windows 7 on an external drive, then what is the relation between the hdd controller which is broken, and installing the Windows 7 on an external drive?

installing win7 on an external drive means that you will be running the laptop on a USB port. and that means you have to select 'boot from USB' option in the bios settings.

yes. the HDD controller is broken, but the USB controller is not.
but expect SLOWER boot times and load times due to the fact that you are running off a USB HDD.
