Creating a bootable USB is very easy and requires just 10 t 15 minutes based upon the specifications of your device. There are lots of tools available on the Internet for this purpose, and if I have to recommend one, I will opt for “RUFUS” due to its useful yet manageable user interface.

  1. Windows 10 ISO.
  2. USB with 8GB storage capacity (minimum).

In most cases, users have Intel processors in their devices. MBR is for Intel’s 3rd gen or older and GPT is for 4th gen or higher. (Figure 3)
