A friend gave me her computer to check.
It can't boot.
The initial error was 000000e > a required device isn't connected or can't be accessed.
I created a Windows 10 media creation tool and tried Method 1 here: FIX: A required device isn't connected or can't be accessed 0x000000E on Windows 10/8/8.1 - WinTips.org
However, I am still getting this: Total identified Windows installations: 0
After that, I removed the disk (it's an SSD actually) and put it in an external case. It flashes, and shows for a while system reserve as a disk (D). Sometimes, disk E also appears and disappears (it's the SSD). Then, everything disappears, and again the same thing.
I put the SSD back in the computer, and now I'm getting a different error: 000000f > BCD is missing or corrupted.
I tried to run Diskpart > list disk > list partition (the Windows disk and partition are shown), but I get the error: Diskpart has encountered an error. A device which does not exist was specified.
Is the disk dead or there is something I miss?
