How to Enable USB Booting From Removable Disks/Pen Drives for Installing Windows 7 Operating System
It is a feasible way to use USB drives for the installation of Windows Operating system rather than using CD/DVD drives. USB installation will help us to save time and cost.
This method also helps user systems having CD/DVD hardware issue.
Steps To Create USB Bootable
1. Insert USB drive in the System and backup all the data from the disk. We need to format the disk to make the drive bootable.
2. Open command (CMD) prompt in administrator mode.
Go to -> Windows Start menu -> All Programs -> Accessories -> right click on command prompt and select Run as Administrator.
3. If prompted security warning, Click Yes to continue.
4. Enter the following commands in CMD,
- DISKPART hit enter.
- LIST DISK hit enter.
The “LIST DISK’ command displays all the disk volumes connected to the system. Choose the correct disk number. Here my USB connection is listed as DISK 1 (4GB).
Be sure to select the correct disk volume number.
5. Enter the following commands and hit enter.
- SELECT DISK 1 (Replace the disk number according to the USB connection)
- CREATE PARTITION PRIMARY
- SELECT PARTITION 1
- FORMAT FS=NTFS
Don’t close the CMD prompt, we need to execute one more command.
6. Insert Windows DVD in DVD drive and note the drive letter. Copy all the contents to the removal disk.
If you are using Windows ISO file, extract the contents to the Removal disk using extractor application.
Extract the ISO file to the Removal disk. (Use WinRAR like decompression application)
7. Skip this step for Windows7 users.
Note the DVD and USB removal disk drive letters.
Go back to Command prompt and execute the following commands.
D: (Replace D: with DVD drive letter)
(Replace G: with USB Removal disk drive letter)
If the command window is not running as Administrator (Windows Start menu-> All Programs-> Accessories-> right click on command prompt and select Run as Administrator), you will get the “BOOTMGR compatible error”.
8. Reboot the system and enter into system BIOS setup and enable USB booting. Change the boot order and enable USB boot to first bootable option. Restart the system.
