    No BCD and WINRE not seeing optane


    I think this install is screwed but I will try here anyway. To start from the beginning, I was using my Lenovo C940 as usual and then shut it. Couple days later I open it and it doesn't boot. It was doing a pretty common (with these) sort of loop where the caps lock light and the screen would turn on (screen black) then laptop shut off. So I purchased a CH341A and reflashed the crappy Lenovo Bios which fixed that problem. Then my Windows wouldn't boot so I used the media creation tool to make a disk and used the command prompt to try and fix the BCD cause I thought that was the problem. Mainly got access denied errors...some suggested deleting the EFI and then rebuilding it. I was able to delete and recreate the partition but could not rebuild it so that's gone. Then I remembered this drive has Optane and I noticed 27 gb volume in diskpart that's not accessible. I looked in my Windows installation and it looks new, I cant find any user data of mine. My most important stuff is backed up but there is some stuff I'd love to be able to recover. I know I'm in over my head and I'm not sure what caused all this in the first place. Any advice?

    windows installation media can see the disk but winre cant?

    you could borrow my boot media so you can see what you are doing: it has explorer, disk mgmt, and plenty of tools:

    Thanks for the boot media, I should have been more clear, winre and booting from the installation media saw what I believe is the 27gb optane cache as unformatted or raw. Your media sees it the same way although it is a lot easier to use. Thanks for it. I'm not sure if it is seen that way due to missing optane drivers?

    Optane drivers are already integrated in my boot media.

    I don't know nothing about your boot tool.

    Attempted this, got "Failure when attempting to copy boot files." I've tried a variation of this before I think with the same result

    I tried using NT6Repair and also got "Failure when attempting to copy boot files." I'm not sure why the optane drive is not working correctly or why I cant seem to find any files at all of my own...
