Installing from USB pen drive is the best alternate for cd/dvd booting because it is sometimes hazzle to carry around the digital discs.
To be frank, what inspired me to write this post is my “Faulty DVD-ROM”.
**Requirements:
**
- You will need atleast 8GB pendrive because,
- If you want to install OS from an existing DVD, it’s size will be around 4.7 GB.
- In a 4 GB pendrive the space is about 3.93 GB only, so 8GB pendrive is required.
- Here is the special case: If the size of OS is less than 3.9 GB, a 4GB Pndrive will suffice.
2. Now, format the pendrive so as to remove any unwanted files which might lead to failure of installation of Operating system.
- Next, open the OS-DVD in a computer and Select all the files in it and copy it to the pendrive.
- That’s it, our Boot-able pendrive is ready.
**Procedure:
1. Connect the pendrive to the system that is to be formatted.
2.Now restart the system.
- Remember, by default system is set recognize “DVD-ROM” as primary device for booting/installing OS.
- So, we need change that order priority.
- While the system is restarting when the manufacturer menu is displayed press F2 or F8 or F12 to enter device settings(depends on the manufacturer to press which fucntion key.
- In the boot priority menu change the USB device to first place.
- The system will reboot again, this time “Press any key to continue” dialogue is displayed because the bootable pendrive is detected.
- From now it is similar to install an OS from CD/DVD.
