Problem with win 10 update

[#1]

I let one of my PC update windows automatically, it updated last night, this morning some of my software does not work (SAGE), so I restored to the previous restore point, this seemed to run OK, the PC reboots and now I get 'missing operating system'.

Going into the BIOS reveals the hard disk is present and recognized (it is a 25GB SSD disc).

I'm guessing as part of the upgrade the disc failed.

Replacing the hard disk is easy enough but how do I install the WIN 10 OS  without a product key

You should be able to download Windows media creation tool to a USB
You don't need a key it should install via your hardware setup it remembered

I love how it remembers your mobo

I can confirm 1st hand that the activation troubleshooter works as I am on my 4th motherboard since originally installing Windows 10

@St3 love how it remembers your mobo   - was surprised

It's well worthwhile having a peep at your disks SMART data every few months.

@VileReynard How is the best way to do that?

On a different note Crashed SSD disks change hands on ebay for > £20 anyone know why?

With technical know-how (ie knowing how to use Google properly) many of the "failed" SSDs can be easily fixed = worth something.

It's all very well being able to use a search engine but that doesn't mean you'll be able to understand the content of the results it produces.
