If you want to install window using your pendrive then this post is for you. To install a window using pendrive you just need to make your pendrive bootable.
The process to make a pendrive bootable is very simple. Please follow below steps to enjoy bootable pendrive (steps for window system only) -
Run command prompt as administrator. Use any of following method-
Click Start -> type CMD in the search text field -> press CTRL + Shift + Enter.
Start -> All Programs -> Accessories -> right-click on the Command Prompt menu item -> select Run as Administrator
Be sure that your pendrive is plugged in, and at the command prompt, type cd c:\windows\system32 to change the directory to the Windows system32 directory -> type DISKPART and press Enter -> Type LIST DISK and press Enter.
You will find a list of disk drives connected to your computer. Find the disk number of your pendrive -> Type SELECT DISK [pendrive number]. It should now state that your USB drive(pendrive) is the selected disk. If you're not sure what disk is the pendrive, remove the pendrive, perform step two again, connect the pendrive again, and compare the results. Generally the pendrive will be the last one.
Type following one by one and press enter-
CREATE PARTITION PRIMARY
SELECT PARTITION 1
FORMAT FS=NTFS (It will take few minutes. Time depends on pendrive's size.)
Congrats! You have done. You can use it now. Copy the window and paste it to pendrive.
