Windows 10: Cannot find boot drive after being forced to update Windows

I got a message that an update was required as support for my version of Windows 10 was not support as it was a version before April of 2018. However, after the update completed and the PC attempted a restart, I get an error that a boot drive is required and it will not load Windows at all. I had a very similar issue when it forced me to update a few months ago which not was a pain to fix but my computer has not been the same since, so this is very frustrating for me.

In my BIOS, it just lists my only drive which is a Crucial P1 1TB. It does not list any other boot options and it is set for that drive, but I get the error mentioned above. Last time this happened it listed my drive twice, one as MBR drive. I have since tried another drive in the system with a previously working version of Windows 10 that was my old drive for that PC which is also encountering the same issue It is a Crucial 250GB MX500 2.5 inch SSD.


My PC has the following hardware:

Gigabyte X470 Auroras motherboard

Ryzen 7 2700X

32GB of Ballistic Tactical DDR4 RAM rated at 3000MT/s 4 modules with 8GB each, same exact model

1TB Crucial P1 NVMe SSD

XFX 8GB RX580


When this first happened, it took a lot of time and effort to get it working again, but at first it would only run the memory at 2400MT/s which previously it worked at the rated 3000MT/s without any issue. It would also often restart before even getting to the BIOS several times without any noticeable pattern; sometimes it did within a few seconds, sometimes within a few minutes, but always would not get to the BIOS the first few or more times.


I replaced the PSU with a better one at that time, but the issue persisted. I also used Memtest 86 which did not find any problems with the memory I though that the system only running the memory at 2400MT/s despite the profile having it at 3000MT/s may show signs that the issue stemmed from the RAM, but I was wrong.

After clocking my memory down to 2933 I was able to boot into Windows, but it would often BSOD and ran the memory at 2400 instead of 2933. So I reverted Windows back to a previous version and it partially fixed the issue. It would still restart a few times before getting to the BIOS, but would be able to boot to Windows 10 and run the memory at 2933 without BSOD.

I did not turn off or had any loss in power during the update; I allowed the update to be uninterrupted and it took about an hour for this last one.

I really need help with this one as this has become a very frustrating issue for me.

Windows 7 booting off wrong drive?!?!?

Please move if this is in the wrong place.

I have two hard drives, a 1.5TB drive, and a 160GB drive. Windows is installed on the 1.5TB drive, as are all my files and programs. The 160GB drive has a bunch of old files, and apparently the bootmgr and boot folder. Nothing else is on the 160GB drive, other than media files etc.

If I remove the 160GB drive from the machine, windows refuses to boot, plug it back in, it works fine. The setup with two hard drives I have now is temporary, as the 160GB drive will go into another machine.

My question is, can someone give me a step by step on how to make windows force to boot off the 1.5TB drive, ignoring the 160GB drive in the boot process completely?
I don't know how to do this in Windows 7, on XP I would just run the /fixmbr command and its related ones.

Any help would be appreciated.

Note: I would really really rather not have to wipe and reinstall, I know it can be done without one as I've had this issue with XP before.

 

Windows 10 forced download

^This, then reboot and go to manually update windows. Find KB3035583 in the list of available updates, right-click and "Hide this update" so it doesn't get installed again next go around.
