Easy Steps: Guide on How to Install Windows 10 Using USB Drive

Speed matters while installing any operating system, especially Windows 10. In this regard, a bootable USB drive outsmarts a DVD always. However, without proper knowledge, things may fall into wrong place as well.

Don’t Worry.

At the end of this article, you will realise how easy it is to install Windows 10 from a bootable USB drive, that too without using any third party application! Isn’t it great? All you have to do is to carry out few instructions in command prompt and you will be having your own Windows 10 bootable USB.

Why go for command prompt?

It’s Error free! This is the biggest reason. Also, the process will not take more than 10 minutes.

What are the requirements?

The process is quite easy and same as that for the previous version of Windows OS.

All you need to have:

  • A USB drive (Minimum 4GB)
  • A Source (Windows 10 ISO or DVD)
  • A Windows PC (7/8/8.1)

Note 1: Don’t forget to check for the version of Windows before proceeding because there are certain limitations. For instance, a bootable USB of 64 bit can’t be prepared for 32 bit Windows version of 7, 8 or 8.1. You need x64 versions for that and same is the rule for creating x86 version of bootable Windows 10 USB.

Finally how to get started?

For the ease of your understanding, the whole process has been described in simplified step-by-step manner. With a little bit of attention, you will get the complete installation idea. So here we go.

Step 1 (Back-up all data in USB)

It is primary to back-up all the data inside the USB to a safe place as the process will wipe out the drive completely. Also, dismount every single hard drive to erase the possibility of selecting a wrong drive for installation.

Step 2 (Set Command Prompt into action)

To do so, type CMD in the START menu followed by pressing Ctrl+ Shift+ Enter keys simultaneously.  


Just navigate through

START menu> Accessories> Command Prompt (Right Click)> Run as administrator> Click on Yes button

Note 2: Run it as administrator to avoid errors. Open elevated prompt by clicking Yes on UAC prompt.

Step 3: (Type the following commands)

Type DISKPART (Press Enter)

Type LIST DISK (Press Enter)

This step will show you all connected disks with their available size and free space. In case only 1 external drive is connected it will be showed as number 1.

Step 4 (Select the disk and go on pressing enter on following commands)

CLEAN > Create partition primary > Select Partition 1 > Active > Format FS=NTFS Quick> Assign> Exit

Note 3: Selection of the wrong disk will cause you loss of whole data in that disk. Therefore, double check before selecting. The same will not happen if you would have worked as advised in step 1.

Note 4: Don’t close the command prompt rather minimize it to the taskbar.

Step 5 (Mount the ISO file)

For Windows 8/8.1

  • Right click on the ISO image
  • Select Mount.
  • Open PC and select the drive letter of it

For Windows 7

  • Do the above through Image mounting software.
  • Note the drive letter

In case you have a DVD of Windows 10, insert the disk into PC and note the drive letter.

Let it be “X” over here.

Step 6: (Complete the remaining commands)

X: CD BOOT (Press enter)

CD BOOT (Press enter)


Here replace P* with your driver letter.

Wait till a message showing “Bootcode was successfully updated on all targeted volumes” will pop up.

Step 7 (Final work)

Now it’s time to keep a copy of all the Windows 10 ISO image contents to the root of USB drive. Finally, your bootable USB drive is ready.

Step 8 (Installing Windows 10 on PC)

Turn on PC and enable booting from USB. It may be required to restart the PC which will be followed by simple instruction. Keep on following that and your PC will wear a new OS suite of Windows at the end.

The process is simple but yet requires a keen attention of the operating individual. However by following the above-said instructions, one can feel it as a cakewalk.
