This article covers formatting Windows 10. Sometimes it happens that our computer may run into some problems. Problems that it cannot recover from or which may persist even after recovery. In some other cases, there may be a problem of slowing down or a virus attack. For such circumstances, you need to go for formatting Windows. Well this may seem like a nightmare to most of the people but trust me, its just a piece of cake.

For formatting Windows, first thing you need to get started is having a bootable USB or a DVD. Well booting via a USB will obviously take less time, I would recommend making a bootable DVD for future such cases.

Making a Windows Bootable Disc:

Just a little reminder. If you are on original Windows, note your product key before hand or create a Microsoft Account. Its to automatically activate Windows whenever you login into a newly installed system. For some laptops like HP, if you have original Windows, you’ll need to re-partition the whole drive.

1. Downloading Windows 10:

For formatting Windows 10, download official Windows only. You don’t want to run into any problems after installation.

  • Go to Microsoft website and download the Media Creation Tool. Run it and follow instructions to download official Windows. You’re gonna need nearly 4.5GB of data for downloading Windows.

  • Choose to save the file as .iso.

2. Burning Windows to Disc:

Normally you would think that burning a system (Windows or any) to a disc is just like burning other files, but its not. You need to make sure that the image you are burning is a ” bootable image ” or not. Otherwise the BIOS will not recognize it as an operating system and will not boot through it.

  • Download Power ISO: This method is the easiest. After installing, right click on the previously downloaded Windows.iso file, select Open With and choose PowerISO from the list.
  • Make sure that its a bootable image. Check the lower left corner. If not, go to Action -> Add Boot Information, browse to the Windows.iso file to open efi folder.

  • Insert a blank DVD and click burn to start writing the disk.

3. Formatting Windows 10:

The procedure for formatting Windows 10 is easy.

Its time to get rid of that slow system. Note the size of your system drive to easily recognize it during formatting Windows. Restart your PC and press F8 or F10 to open Boot Menu. Then choose your DVD and hit enter. Your PC will now boot through the disc. Follow the below steps after that.

  • When the setup starts, this window shows up; hit next. In the next window, choose Install Now.

  • Now the setup will ask you to enter the product key. Enter if you have one or just select ” I don’t have a product key ” and hit next.

  • If you select the above option, you’ll need to choose from the different Windows versions. I would recommend Windows 10 PRO. After this, accept the Microsoft terms and conditions and click next.

  • Now comes the confusing part. There are two options: Upgrade and Custom. While upgrade says that this option will upgrade your Windows, it actually doesn’t. If you select this option, your computer will restart and we’ll back to zero.

Select Custom and click next. You’ll now see many partitions. The bigger ones contain your files and the smaller ones contain the bootloader.

Choosing Partition:

  • You need to format all the partitions whose size is in MB. DO NOT DELETE them, just select and format.

  • Identify your Windows partition by checking its size. It important that you note the size beforehand otherwise you may end up loosing your files. After that, select the partition and format it.
  • Now your Windows is gone and you can install a new one. If you do not format the partition containing Windows, the old Windows will get stored in a folder called Windows.old in your C drive. It may take space upto 50GB, which you’d have to free manually after installation. So the former method is recommended.
  • Select the partition and hit next.

Your work is done here. Now Windows will start installing. It shouldn’t take more than 15 minutes to complete. When the computer restarts, Cortana will greet you and guide you through the setup process.

See, wasn’t hard after all. Just like I said, would be a piece of cake.
