Here, I give a short & simple way to install Windows 7 into your system from a USB drive.The benefit you get with this native support for USB installation is that you can easily install Windows 7 on ultra portable machines & netbooks which don't have optical drives and at the same time, the speed you get while installing from a USB drive is much faster than installing it from an optical drive. So why not give it a try.
Follow the following steps to start off:
| Windows 7 logo |
- Take a 4GB (or higher) flash drive.
- Plug this drive into a Vista or Windows 7 machine.
- Open the 'Command Prompt' with Admin rights by right clicking on the cmd icon & selecting "Run as Administrator".
- Type in 'Diskpart' (without quotes) & hit Enter.
- Type 'list disk'.
- This will show you the number of disks connected to your machine. See which is the one with 4GB space.
- Now run the following commands assuming that the disk name is disk 1, else replace disk 1 with the correct number for your disk.
- Diskpart>Select disk 1
- Diskpart>Clean
- Diskpart>Create Partition primary
- Diskpart>Select partition 1
- Diskpart>Active
- Diskpart>Format fs=ntfs //This will take time
- Diskpart>Assign
- Diskpart>Exit
- Now copy all the content from your Windows 7 DVD to this pen drive.
And it's done. Enjoy a fast installation experience.
Note: The commands only work in Windows Vista or Windows 7.
