I'm having major problems getting my single-boot 64-bit Windows 10 Pro system to boot again. It's a hand-built desktop that has worked fine (with some exceptions) for years. The exceptions I referred to relate to situations just like this one wherein I just can't get it to boot. The error I see now and most commonly in the past is an "Inaccessible boot device" BSOD.
SUMMARY of my question: I'm using EasyBCD to edit the desktop's BCD to ensure that when I boot up, the system partition is set as the boot partition at drive letter "C:". If I set the BCD boot entry to "BOOT", just what does that do?
Full explanation: I'm guessing that there's some problem with the BCD, which is where EasyBCD 2.4 (community edition) becomes indispensable. I'm using it on my Win 10 laptop to load the BCD from the desktop's system SSD, which I've connected directly to the laptop so I can fix any problems with it (such as by running CHKDSK, and offline DISM and SFC). None of which has solved the problem.
So back to EasyBCD. Although I've been using it for many years, I've never been able to figure out what I should choose as the boot drive. Since the laptop's boot drive letter is always "C:", the two-partition desktop SSD drive are assigned D: and E:, with D: holding the Windows 10 system (release 1909). But there are some AutoIt executable scripts and a couple of other executables residing on the second partition on that SSD which are run as Startup applications, all of which expect to be present on drive letter "B:", so I change drive letter "E:" to "B:". On second thought, I see that this was a dumb idea, but I can't fix this until I can boot again. Is this the cause of the "Inaccessible boot device" error? I don't know.
In this OP, all I want to know is the question posed above: If I set the BCD boot entry to "BOOT", just what does that do?
BTW: A little while ago I purchased my third or fourth edition of EasyRE, but it doesn't fix the problem. Just FYI...
Thanks!
