I had a dual boot (Windows 10 and Endless OS), with Windows installed on my primary SSD and Endless on my secondary SSD. This week I formatted Windows, and during the process I only formatted the primary SSD and set it as the installation partition for Windows, meaning the secondary SSD was not touched.
When I started the machine again, I encountered the 0xc000000e error, but I can still start windows by entering the BIOS and restarting (without changing anything). I tried all the solutions I found for restoring the boot (both the system's automatic fixes and the command-line solutions). None worked.
I also tried formatting the secondary SSD where Endless OS was installed (thinking it might be causing some interference). After that, I performed several recovery procedures again and still without success (Note: even though the drive was formatted, Endless still appears on the BIOS screen).
Finally, yesterday I decided to format the machine again. Since the secondary SSD was already formatted and I wanted to keep my personal files, I did a cloud system restore (keeping personal files) using Windows' own tool, but today the problem occurred again.
One detail is that when entering the disk management interface, only two volumes appear on the primary SSD: the C drive where Windows is installed and the D drive that I partitioned after the first format (personal files). No system partitions are displayed for the primary drive (only the UEFI for the secondary SSD).
