When you need to install a Windows OS on multiple devices or a laptop that doesn’t have a DVD ROM, you would need to create a bootable Windows 10 USB. This bootable drive installer is just like a burned DVD or a CD. In this method, we need an original ISO image. You can download it from the Microsoft official site.
There are many alternative ways to make the bootable flash drive it. In this tutorial, I’m going to use the Rufus free application. It can also make Live Ubuntu USB installer too. In this post, I’m not going to cover ISO image creating steps. If you need to know how to create an ISO image using a DVD, you can refer my this how-to tutorial.
This method will wipe the flash drive all the data and copy the ISO files to the root of the device. Therefore, it’s highly recommended to back up the device’s files and folders. No need to use a professional tool, just copy or move files to your computer hard disk. It’s simple and quick.
Create a Windows 10 Bootable USB From ISO ( Flash Drive )
First, download the Rufus windows 10 bootable USB tool from here. It is a free utility, which is compatible with Windows XP to Windows 10. This tiny tool is a portable application, once download we can run it by double click on the Rufus .exe file.
- After you open the tool, click its device drop-down menu and choose the correct USB drive.
- In format, options click the small “DVD” icon, then browse the ISO file location and choose the Windows 10 ISO file. If you need to check for bad sectors, then enable the “Check device for bad blocks” option. This bad sector detecting option will scan the whole device. It will take a couple of minutes, therefore, it will slow down the live USB creating time.
- Once you choose the ISO image, it will automatically select the device file system as NTFS. It’s the most suitable file system for Windows.
- In the “Partition scheme and target system type” select the “MBR partition scheme for BIOS or UEFI computer” option. Keep the “Cluster size” as it is. Type an identifiable name for “New volume label”.
- Next, click “Start”, now it will ask for you to format the USB device. Therefore, before starting this step, it’s better to copy the pen drive files and folders to the computer. If you have an empty device, it will not ask to format.
- The file copying process will take 1-2 minutes. If you can see the progress at the bottom of the Window. Once it’s completed, you can eject the device from the PC and start the installation.
- To boot the computer using a USB device, change the BIOS boot option as a “USB device or optical device”. In some situations, your pen drive will be listed as the manufacturer’s name.
- Then Boot drives select this bootable Windows USB drive as a first drive.
If your computer replaced the old hard drive and replaced a new SSD or Nvme drive, you can easily transfer windows to another drive without wasting your time.
