Installing Windows 7 on USB

Hi All,
Greetings!!!

I have a requirements to install windows 7 on USB. Tried lots of options didn’t work at all.

Before trying all option, I made my Pen drive as bootable using diskpart

Please find the options which I tried as follows,

1. I have applied Wim(captured wim) to the pendrive using Imagex – Didn’t not work
2. Tried with traditional way of installing Windows 7, Disconnected the SATA cable which is connected to HDD. Thought it will show the USB as a mass storage device. But it didn’t detect the USB as device to install the windows 7 – Didn’t not work
3. Took a backup of C drive using Acronics backup tool and applied the backup in pendrive - – Didn’t not work
4. At last found an interesting article http://www.intowindows.com/how-to-install-windows-7-to-usb-external-hard-drive-must-read/
At last step it fails to copy boot files using BOOTSECT.exe – Didn’t not work
5. Created a unattended installation by selecting the Disk as the pen drive and deployed the Image, It was successful but When I boot with pendrive. BOOTMGR is missing - – Didn’t not work


If anyone have a solution for the problem which I am facing. It will be really appreciated!!

There will be master of all. Looking to hear from him..

Hope you might be the one..

Lot of thanks in advance..

Mohan

Other than Windows 8 Enterprise Edition Microsoft has never supported installing any OS to an external drive. It can work (probably not well) on some hardware.
