Formatting a drive with windows 10 on it

Hi Calvin

Formatting the drive will require erasing it to make it usable for additional storage. Formatting it will not delete your license though, you will still have the option of reinstalling the drive if necessary and reinstall Windows 10.

When you upgraded from a previous version of Windows or receive a new computer preinstalled with Windows 10, what happened is the hardware (your PC) will get a digital entitlement, where a unique signature of the computer will be stored on Microsoft Activation Servers. The Windows 7 or Windows 8 genuine license you were previously running will be exchanged for a diagnostics key.

Anytime you need to reinstall Windows 10 on that machine, just proceed to reinstall Windows 10. It will automatically reactivate. You will prompted to enter a product key a couple times through the installation, click I don't have a key and Do this later.

There is no need to know or get a new key, but if you have issues with Digital Licensing or the Activation Troubleshooter, you can utilize an existing Windows 7 or Windows 8/8.1 product key you already own to reactivate if necessary. or use the reset function in Windows 10.

Go to a working computer, download, create a bootable copy, then perform a clean install.

Once your computer is set to boot from the DVD, you should see this option. If you are installing from a retail Windows 10 USB thumb drive, you will be asked to select either 32 or 64 bit Windows 10. Learn more here https://www.groovypost.com/howto/choose-windows...

The Windows logo will appear on screen, this might be here for a while, as long as you see the animating dots, everything should be ok.

Select your Language, Time and Keyboard method then click Next.

Click Install now

Windows 10 setup will prompt you for a product key during installation a couple times. If you originally upgraded from Windows 7 or Windows 8/8.1 click the option 'I don't have a key' and 'Do this later' . If you have a Windows 10 product key, you can proceed to enter it.

Setup will also prompt you to select the edition you have a license for - Home or Pro. Please make sure you choose the right edition. If you choose the wrong edition, your only option will be to perform a clean install again.

The copy of Windows 10 you download and upgrade from will correspond with the edition of Windows you have installed, if it does not, this is why you might be experiencing problems activating:

Windows 7 Starter, Home Basic, Home Premium, Windows 8.0 Core, Windows 8.1 Core should install Windows 10 Home 



Windows 7 Professional, Windows 7 Ultimate, Windows 8.0 Pro, Windows 8.1 Pro should install Windows 10 Pro

IF YOU ARE NOT SURE WHICH EDITION YOUR SYSTEM CAME WITH, CHOOSE WINDOWS 10 HOME.

Wait while setup prepares to copy files

Accept the license terms then click Next

Click Custom: Install Windows only (advanced)

NOTE: Sometimes Windows 10 setup can become confused if it see's a thumb drive. You might get a driver missing error or something to that effect. If you do, restart setup, but this time, when you arrive at the following screen, disconnect your thumb drive then go through Custom options. When setup is ready copy files, it will prompt you to reconnect the installation source (your USB).

Select the drive then click New

NOTE: If you have multiple partitions listed, select each one (starting at the bottom), then click delete until there is only a single (one) unallocated drive displayed in the window.

Select the unallocated drive listed, click New, click Apply then OK

This will split the drive into multiple partitions, select the Primary partition then click Next.

NOTE: The System Reserved partition is where recovery files are kept for diagnostics and repairing damaged Windows 10 files; or even reinstall Windows 10.

Wait while Windows installs

When this phase of setup is complete, Windows will automatically restart then reboot into setup again.

Windows is detecting and installing your hardware. After this is complete, Windows will restart one last time.
