This is a long story but after a frustrating day dealing with Microsoft Window there may be some useful information in here for some of you.
Two days ago I noticed one of my PCs which I use for a server on my home network wasn't working. The fans were spinning but there was nothing on the monitor. It is a Windows 10 PC I have had for years. My first reaction to problems like this which I have seen before, is to power down the PC, turn off the power supply for about 40 seconds and reboot. That usually solves most issues when Windows gets confused and stops working. This time, Windows 10 started loading but then a message popped up on the screen that a bootable device could not be loaded and the PC would automatically restart (because even Window 10 knows that rebooting solves most of it's horrific code bugs.)
When the system rebooted it went into repair mode - the dreaded black hole of spinning dots with absolutely no information provided to the user. This usually takes anywhere from 5 minutes to an hour depending on the speed of the processor. Of course, this process did nothing and told me nothing. It would have been nice to tell me what device was having a problem because then I would be able to troubleshoot that one devices - or even remove it. I knew it could not be the primary HD where Windows was installed because it started to load Windows from that drive before failing, plus it is an SSD with no moving parts so it is unlikely that was the problem. After running diagnostics (provided by Microsoft) it suggested reloading Windows 10. After hours of frustration I did just that. Of course this means losing all programs and settings, but since this is a server there was not much on it. The process supposedly saves files but I found out later that isn't exactly true. If saved some files on the primary drive up to 2022 but anything since them was lost.
Reloading Windows 10 did not work either. Windows installed but then on reboot I got the same error message that it can't load a bootable device. Out of frustration and a last resort I decided to clear the CMOS and try again. That worked. The system rebooted and I was immediately able to find a problem. Clearing CMOS turned off RAID mode for two 6 TB HDDs I use for file storage, backups etc. But only 1 of the 2 drives was showing in file explorer. After checking physical connections I looked at the status of the 2 drives and the "dead" one appeared unallocated. Since it was RAID 1 (mirrored) I thought I could reallocate the drive, format it and load RAID again. the good drive would copy itself to the mirrored drive automatically and everything would be back to normal. So I reallocated and formatted the drive, then rebooted and reset the BIOs to turn RAID back on. When the system rebooted I got the same error message as before that a bootable device could not be loaded. This is when I realized the error message is a generic message that means nothing. A RAID array for storage is not a bootable device and I have had RAID drives fail many times without rendering the system unbootable, although this was a first in Windows 10. Question: Why not include information about the device that is failing to load? The system must know what it is trying to do when it runs into a problem. Even the name of the driver it can't install or that is not working would have tipped me off to the problem immediately. Microsoft is awful this way.
After trying for hours turning RAID on and off and not being able to find the problem I kept digging only to find a weird solution. Boot the system with RAID mode off, set the PC to boot in safe mode then restart turning RAID mode on before it reboots in safe mode. Why? Who knows but apparently this tells windows to reload the RAID drivers! Again, why? Welcome to the underworld of Windows and Microsoft. This worked but I had to reallocate both drives and reformat them losing all files on the drive. Luckily, at some point I thought it might be a good idea to backup my mirrored drives as one additional step of redundancy. I was able to recover most of what I lost. This is kind of stupid because the entire purpose of RAID 1 is redundancy. If one drive fails, the other operates the same without mirroring and no data is lost. Then replacing the bad drive is a simple process and mirroring works automatically again.
I have no idea what caused this problem to start out of nowhere. The system logs showed nothing. I have never found the Windows system logs to be helpful on system crashes. Most o the time all you get is a message that the system shut down unexpectedly and rebooted. Gee, thanks Sherlock! I never would have figured that out from the blue screen I just witnessed!
In any case, if you use RAID in Windows 10, remember this process if you see a problem like this. Boot into safe mode with RAID off. Then reboot, turn on RAID in the BIOS and then reboot without safe mode and the problem should be resolved.
And don't forget to back up your RAID arrays, even RAID 1 because Microsoft has no idea how that is supposed to work!
