Windows 10: LOST EVERYTHING...NEED HELP PLEASE

I have an HP Stream 360 Laptop, Windows 8.1. My entire Operating System is gone. I've tried everything to fix....ISO disk image, original drivers, diskpart, command prompt, every resource and solution I could find. NOTHING has helped or has worked.

I cannot get to any screens or anything at all for that matter. At this time the only working keys are the power button and the F2...etc. keys. I have a new flash drive that has never been used.

Lost default photo viewer after profile rebuild

Thanks Brink. I've tried those steps before i started searching Google. After the profile rebuild i don't have the Photo app listed to choose to make it default in either the system settings for default apps or the Open With option.

I can't even find it doing a search. Seems to have been removed somehow with the profile rebuild, which doesn't make sense.

Might be helpful to list what i've done I've done the open with check, the choose default program in the system menu, tried that in device manager default programs also. I've checked the programs and features Turn windows features on/off and it's not listed there (never thought it was but that was a suggestion), searched the MS Store, it's not listed there either.

I don't like playing in the registry unless i have defined steps and haven't found anything for this yet, just the Win7 version like in my OP.

 

Lost data from hard drive, what to do now?

Well, I'm sorry to hear that it's a WD My Passport that failed on you, @tomhenry ! *Frown
I'd recommend you to try using a different USB cable with it and see if that will help your system to detect it without it disconnecting.
I'd also suggest you to go to Disk Management and see how the drive is listed there. It won't hurt to check up on the health and SMART status of the HDD by running the QUICK and EXTENDED tests from the WD's Data LifeGuard Diagnostics. Here's a link to the available software: http://products.wdc.com/support/kb.ashx?id=11ZOpD
