If you don't find any of these features, try these steps:
Download the tool multimedia creation by Microsoft which will create a USB flash drive (minimum 4GB) bootable with Windows 10. It may be necessary to use a functioning computer to do this if yours does not boot into Windows. Keep this unit safe also for future reinstallations.

- When the PC has booted correctly from the USB flash drive, you will see a Windows logo and then a screen like the one below where you choose the language. Just follow the instructions and make sure you choose the correct hard drive and partition on which to install Windows. If it is a new unit, it will be empty, so choose the only available option: the large unallocated space.
- Once the installation has started, the PC will restart. You will see a Windows logo and a large circular progress indicator. Keep an eye on the installation as it will restart your computer several times and may ask you to remove the DVD or flash drive.
