Windows 10: Error 0x8007007B after replacing the hard drive

My friend bought a used laptop with a licensed Windows 10 Home Edition. Recently, she decided to upgrade it by adding more RAM and an SSD drive. I installed Windows 10 Home Edition for her and tried to activate the license, but it failed. I booted it from the old drive, deactivated the license on it, and tried to activate the license again on the new one, but it still failed. Error 0x8007007B.

Replacing a laptop hard drive with a SSD

I have a Dell Latitude E5420 laptop which has a Windows 10 Pro O/S. I would appreciate a step by step guide on the procedure to replace the hard drive with a Solid State drive; specifically dealing with the transfer of all the software from the old drive to the new. I have an external hard drive I use for backups and a free version of the Macrium Reflect program on the hard drive. The SSD is brand new. I have just 50 GB in total on the 231 GB hard drive. The SSD has 250 GB capacity.

 

Overclock your hard drive!!!

Heres a much easier hack that I realized quite a few years ago that really does work!

REQUIREMENTS:

• Hard drive with molex power connection.
• PSU with more than 1 strand that has molex plugs on it.
• Wire strippers, soldering iron if you're fancy, electrical tape if you're not.

STEPS:

• Take the strand of connectors from your PSU, and decide which one will be the donator for this overclocking adventure.
• Cut the yellow and orange cables, then twist them together.
• Find the power connector you've chosen as the overclocking connector, and release the orange cable from the connector. Now use your preferred method to bind them together, then place it back together.
• Plug in a drive and feel the speed!

Congratulations! You've just overclocked your hard drive!
