    This thread may get confusing with multiple OP on one thread.

    Perhaps each OP can start a brand new thread?

    Also, when i tried to do "Bootrec /Fixboot" it comes up with "access is denied"
    I also did "sfc /scannow" and it came out with "Windows Resource Protection did not find any integrity violations"
    Today is the 23rd Jan my computer went into Inaccessible boot device AGAIN. and i had to restore. AGAIN. my computer works fine after each restore but its really annoying how it keeps happening.
    Windows Malicious Software Removal Tool January 2018 (KB890830) keeps updating each time. I have other apps that needed updating like Razer Synapse 3 and Java. As of right now, I have no idea what is causing the problem.
    Also after each "inaccessible boot device" it restarts and throws me into the BIOS with this message https://media.discordapp.net/attachm...205&height=904

    That's the most annoying part of the inaccessible boot device error, not knowing what causing it. This is a pretty good tool for restoring the boot record:

    Dual-boot Repair Windows 10

    A portable app, that runs in Windows. Starting up the dual boot repair tool presents a number of options:

    Worked for me, but your mileage may vary....

    I did not try running this app in a recovery environment, such as WinPE, but it would probably run there as well...

    Have you upgrade the BIOS/UEFI firmware check your motherboard manufacturer website for latest newer version of BIOS/UEFI firmware upgrade and install it if there is one.

    Today, the inaccessible boot device came back. I have already used Dual-boot repair windows 10 that Cr00zng suggested so that seemed to be ineffective for me. I restored my PC again in order to access it and download the BIOS update I was going to install. I have updated my Gigabyte Z270X K7 BIOS from F3 to F9a (Jan 2018 version) literally 5 minutes ago. If the inaccessible boot device thing comes back, I will be sure to post.

    One other thing is that the SSD i have windows installed on does not show up as a selectable option in the BIOS boot priority list. My PC can only boot to it because Windows Boot Manager has automatically selected my SSD to boot from and Windows Boot Manager itself is a selectable option. So I have selected Windows Boot Manager as the top priority.

    I am not sure if this could be the problem. I have left my BIOS to boot "Legacy" mode because i have always left it that way.

    Also, I have noticed something when I ran "systeminfo" in cmd. Does this mean anything? (picture) https://i.imgur.com/BYA7ptp.png

    Please post screenshot of Disk Management console.

    You can open the Disk Management console by typing Diskmgmt.msc into Start Menu.

    I'm away from my PC at the moment but I remember doing this earlier today when searching up stuff. It came out with my 2 drives. SSD and HDD. 250GB and 2TB. And it also had 2 things labeled (Disk 0 partition #) I remember one was 45MB. I dont remember the other one but it was bigger and both did not have a file system.

    Every drive is Healthy
    I only remember this much. For the full screenshot I guess we will have to wait until tomorrow.
