Having played with W10 for a while as an upgrade, a nice new 500Gb SSD arrived yesterday, so, it was time for a clean install.
I created a USB boot media. Booted from that and installed windows to the new drive. All well and good. Except I needed to change the boot sequence once that was complete so install booted from the new drive.
Had the old drive connected still so Windows would activate ok. All done ok.
All done, fresh, clean install of windows. Of course now, as the old drive was still connected, W10 offered me a choice of which drive to boot from.
Disconnected the old drive and... it wouldn't boot. So I put the USB back in, booted from that. Thankfully there's an option to fix boot issues (I bet they knew what would happen) and that fixed it.
So there we have it. I have a clean install of W10 on my new drive and everything is super speedy
It didn't take me long to find the start menu either. That's in C:\Program Data\Microsoft\Windows\Start Menu\Programs - I usually add the 'Programs' folder as a taskbar toolbar so I have that nice fly-out menu, missing since XP's demise.
