Win 10 upgrade seems to have crashed SSD

Hello All,

My Toshiba Tecra W50 was running fine on Windows 7. Regrettably, I overlooked disabling the popup which automatically scheduled and performed the upgrade to 10.

While just exploring a bit to decide whether to keep 10 or use the Settings app to return to 7, I started getting "drive failure imminent" messages. Having just gotten the PC back from Toshiba for a repair of the SSD, it seemed a huge coincidence that the drive might actually be failing immediately after the first Win 10 boot.

Thinking that 10 was the error, I decided to downgrade back to 7. That process seemed to proceed to completion, but now the computer won't boot.

On power-up, you get the familiar "Starting Windows" flash screen, then it goes to a text screen that says Windows failed to load and gives you the option to run a startup fix. Clicking that, after a short delay, leads to a message that says it can't fix it.

I'm stuck. Where do I go from here?

I'm happy to provide more specifics - the above is just to lay out the problem.

Thanks in advance to all. I'll be searching and reading messages until I hear from you.

A clean install of Windows (either 7 or 10) would probably be your best bet to permanently fix the problems.

Well, sure. Although I don't have any way to do a clean 10 install, and at this point don't really want to even start reopening that can of worms. Just want to get back to 7 and get back to work.

I'm hoping someone knows a way to get going without starting over from scratch. There's a lot of time invested in this computer that I'd sure like to avoid redoing.
