On a Windows box (in this case I use Windows 10 but you can do this lab in Windows 7 or Windows 8), do the followings:
- Insert the Windows 10 DVD (H: drive in my case)
- Insert a USB stick (later G: drive in my case, after I format it)
Launch the Command Prompt as Admin, type diskpart, press Enter.
After that, type list disk to list all available disks on the system.
In my case, the USB drive is disk 4, so I select that disk by typing:
select disk 4
Next we will select the disk 4, create an active partition and format it with NTFS file system.
Commands are typed in the CMD prompt one after the other:
select disk 4
create partition primary
select partition 1
Wait till the format is complete.
Type assign to assign a drive letter, then exit diskpart.
Now change your drive to H: and change directory to Boot (where H: is the DVD drive that contains the Windows 10 DVD contents).
Type the commands:
Now create a bootsector for the USB drive to allow it to be bootable. In my case, the USB drive letter is G:. Type
bootsect.exe /nt60 G:
Now we need to copy all files in H: to G:. Select all files and folders in H:\, copy them.
Paste the contents onto G:. The process will take a couple of minutes to complete.
Once the copying process finishes, you can boot a computer off of the USB drive. Make sure to change the boot sequence to prioritize the USB device in the BIOS of your motherboard.
