Solution:
Enter BIOS setup by tapping the key shown on first screen at reboot. Reset the BIOS to Defaults, then if necessary set the SATA controller to AHCI.
While in BIOS look around to see if there are any settings for UEFI, CSM, Legacy BIOS or Secure Boot which would indicate you have a UEFI BIOS that must have its installation media booted as an EFI flash stick.
It’s correct to delete all partitions but may need the extra step of wiping the drive of boot code and partition table to get it cleaner. At first installer screen press Shift + F10 to open a Command Prompt to run Diskpart Clean Command.
To make sure the wrong partition isn’t chosen just highlight Unallocated Space to click Next at the Drive Selection screen to let the installer auto-create and format partitions to begin.
If failure persists I’d test the hard drive using the maker’s HD Diagnostic
extended CD scan, and the RAM – Test with Memtest86+ for 5-6 passes or overnight to stress it. Check that RAM slots are clean and free of dust, swap sticks, try install with only one.
1/ How to Clean Install Windows 10
Change the Boot Device:
The very first thing that you need to do is to change the boot device and make sure that the USB installation media is connected to your computer before you do so. You can do this by entering the boot device menu in your computer’s BIOS setup. Just press F12, F9, F2 or any required function key to be pressed when your computer starts up.
2/ Follow the Process Shown by the Windows Install Wizard
Once your computer boots from the USB installation media, the Windows Install Wizard should then initiate. From here, you will simply need to follow the steps because it is there to guide you. You will need to prepare your product key at this stage but if you don’t have it yet, you can input it later on and just skip the step that asks for it.
