Windows 10: Windows BSOD:"Unmountable Boot Volume" and Windows 10 black screen after "Preparing...

Hello,So Yesterday my computer randomly restarted. So i turned it on again and it somehow changed the Boot Order by itself. So I Went to the BIOS and changed it back to normal.


When i did,Saved Changes and everything. I restarted my pc and after the Windows Logo Loading Thing it showed a Blue Screen Error with stop code: Unmountable Boot Volume. So IT automatically restarted my pc and then said "Preparing Automatic Repair" and randomly just becomes a BLACK SCREEN.I wanted to go to the Windows troubleshoot screen, people said to wait 30-45 Minutes and it will show the "repair your PC" thing, but it didn't.


So the next thing I tried was to use my Windows 10 Bootable USB. I booted from it, and after that it shows multiple dots Moving in a vertical line in the middle of the screen. I couldn't repair my PC through my bootable drive.


So, What i did was took out the SATA data and SATA power cables of both my Hard Disks, And tried to boot from my USB alone.It worked and didnt show those dots this time.But obviously, I can't fix my HDD like that.


So,What do i do to fix this?Can anyone please help.

:)

Need help on BSOD "Unmountable boot volume"

So I receive an update for "Windows 10 Creators" before doing the update I decided to create a recovery disc to a USB but only to find out I can't create one with error "Missing important files" so I googled and found a thread that suggest a steps... one of the step is to supply a command (in administrator level) a "reagentc /disable" this freezed my laptop and then windows crashes and restart. During the restart just after the Asus loading logo the BSOD with "unmountable boot volume" error code occurred I tried many restarts but same error being display.

With the "unmountable boot volume" error, I googled and found that I have to use a bootable USB to fix it (I don't have installation CD when I bought the laptop). I grabbed other laptop (with windows 10 installed) and create a windows 10 bootable in USB. Go back to my damaged laptop I changed the boot sequence to boot in my USB but after the Asus loading logo the screen goes black and stuck there the installation which usually popups didn't displayed. I tried on the other laptop where I created the bootable USB to check if the USB is damaged but to my surprise the bootable USB actually works on the other laptop no black screen displayed.

I created the Windows 10 bootable USB using Rufus, then when the black screen is being displayed I tried to create again with the Windows Media Creation Tool which also display black screen.

At this point I'm not sure what to do to fix this... any idea is appreciated...
