Gone the old days of DVDs, no one uses DVD to install Windows now. The best and suitable option is to make a flash disk bootable using cmd and install Windows 10 or 8.1 & 7. There are some tools to create bootable USB drive or Pendrive. But why would you install a third-party app when you can make a bootable flash drive using cmd (command prompt)?
Flash drives are not only useful to transfer data but you can use them for different purposes. One of them is to install Windows XP, 7, 8/8.1, or Windows 10. Even you can install Linux OS as well.
Probably every computer owner owns a USB flash drive which makes it easier to install any version of Windows on your PC.
Cmd is a powerful tool to perform different tasks if you know the commands. Third-party tools can help to make flash drive bootable including Microsoft Official USB Installer. These tools do nothing but automate the process.
Many such tools have limitations and take a long time to format and write Windows files into the USB flash drive. Some tools also cost money.
How To Make Flash Drive Bootable Using CMD (Command Prompt)
Here is a simple way to turn USB flash drive into bootable media to install any version of Windows like XP, 7, 8, 8.1, and Windows 10.
All you need is a flash drive with a storage capacity of 4-8 GB. 4 GB for Windows XP, 7, 8, and 8 GB for Windows 8.1 and 10, and the downloaded iso file of Windows.
Follow these steps to make flash drive bootable using cmd-
1. Insert your Flash Drive and go to start, search for CMD.
2. Right-click on it and Run as Administrator.
3. Once the command prompt is open.
Type diskpart and hit enter. It will enter into the disk partition management mode.
4. Typelist disk and hit enter. Here you can see all the disks on your computer, it doesn't show disk partitions but a list of the connected disk into your computer.
5. After you get the list of disks, find your flash drive by its size. Here mine is 14 GB which is Disk 2.
Now let's select the flash drive by typing select disk <disk no.> eg select disk 2 and hit enter.
6. Once the USB flash drive is selected type cleanand hit enter.
This command will erase everything from the flash drive. Make sure it does not contain your important files.
7. Now you need to make your flash drive a primary partition to do so-
Type create partition primary and hit enter.
8. Once the disk is a primary partition you need to make it an active drive.
Type active and hit enter on your keyboard. The command will activate the flash drive.
9. Now you have to format the flash drive.
Type format fs=fat32 quick and hit enter. This command will format the flash drive in quick mode.
FAT32 files system works with Windows 8.1 and the lower version of Windows. But if you are installing Windows 10 then you need to use an NTFS disk.
Windows 10 contains a file names install.wimthat is larger than 4GB. FAT32 does not support copying files larger than 4 GB.
So you need to format as format fs=ntfs quickand it will work.
The early version of Windows 10 supported FAT32 but Windows 10 version 1903, 1909, 2004, & 20H2 do not support FAT32. So use NTFS instead.
10. Once the flash drive is formatted you may not see it on My Computer.
To get it back you need to assign a literal to it, type assign and hit enter.
All done you just made your USB flash drive bootable using cmd, close this command prompt by typing exitand hit Enter.
