Install Windows 10 from a USB Flash Drive

Install Windows 10 from a USB Flash Drive

 

Steps

1. Insert a usb drive at least 4gb in size

2. Open a command prompt as administrator

Hit Windows Key, type cmd and hit Ctrl+Shift+Enter. This will force it to open as admin.

3. Run diskpart

This will open and run the Diskpart command line utility, which allows you to manage disks, partitions and volumes.

C:\Windows\system32> diskpart

4. Run list disk

This will list all disks on your system. You’ll see the something similar to this:

DISKPART> list disk Disk ### Status Size Free Dyn Gpt -------- ------------- ------- ------- --- --- Disk 0 Online 238 GB 0 B Disk 1 Online 465 GB 0 B Disk 2 Online 29 GB 0 B

5. Select your flash drive by running select disk #

Find the item that corresponds with your flash drive and select the disk. In the example above, my flash drive is disk 2 so I’ll run:

DISKPART> select disk 2 Disk 2 is now the selected disk.

6. Run clean

WARNING: This deletes all data on your drive

The clean command marks all data on the drive as deleted and therefore removes all partitions and volumes. Make sure you want to do this! If you are sure, run:

DISKPART> clean

7. Create a partition

DISKPART> create partition primary

8. Select the new partition

Since we know there is only one partition, we can just run this:

DISKPART> select partition 1

Without checking the partition number. If you’re really curious, run list partition to check.

9. Format the partition

To format it, we’ll use the NTFS file system and run a quick format:

DISKPART> format fs=ntfs quick

10. Set the current partition as Active

Run:

DISKPART> active

11. Exit diskpart

Run exit. This will exit diskpar
