Also, before you get ahead make sure you have legacy support enabled, which can be done with the above step. If the legacy support option is not enabled then the laptop won’t be able to detect the pen drive, and you won’t be able to install Windows.

  • Insert the bootable USB drive that has the Windows setup.
  • Turn on the HP laptop and press F9 to open boot manager in BIOS.
  • Select your bootable media to enter the Windows 10 setup.
  • Follow the instructions to install Windows. If your laptop was already having Windows 10 activated, then you wouldn’t have to enter the activation key again.
  • When asked to choose the partition, make sure you select a different partition and not the one that already has the Windows.

Note-This way you will be able to take a backup of your files from the previous version of windows. If you already have the backup, and then you can reset all the partitions. After resetting the partition, all your data will be lost, so make sure you only do it if you have the backup.
