Windows 10: Can't find device to boot from

This morning, I was on my computer, I turned it off. Then I returned from school and when I started it up, suddenly I heard this beaping noise, then it went to the windows loading screen, it fully loaded then the screen said "Can't find device to boot from", out of shock I went to YouTube 5i find a trouble shoot, and ithe video I watched said it had to do something with your hard drive. I did the windows built in diagnostic test and everything came back clear but on some of the diagnostic test, some of the results for the hard drive Were "Grey" or one with a ⚠ sign. I think this has something to do with my hard drive might be loose but I really don't know, I tried unscrewing it but it wouldn't do so, so I would really like a second opinion on the situation from the developers, please help me, I need to use my computer for recreational activities.

BSOD - Inaccessible Boot Device


The reset save files equivalent if successful should be the quickest method to get you backup and running.

The backup files then clean install is the best option as you fix many problems and start fresh.

The command prompt commands are all trial and error.

Code:

Code:

1) bcdedit /enum  2) bcdedit | find "osdevice"  (note the partition drive letter displayed in the result as this drive letter will be used in many of the later commands)

Code:

Code:

3) diskpart  list disk  list volume  select disk 0  detail disk  list partition  select partition 1  detail partition  select partition 2  detail partition  select partition 3  detail partition  select partition 4  detail partition  select partition 5  detail partition  select disk 1  detail disk  list partition  select partition 1  detail partition  select partition 2  detail partition  select partition 3  detail partition  select partition 4  detail partition  select disk 2  detail disk  list partition  select partition 1  detail partition  select partition 2  detail partition  select partition 3  detail partition  select partition 4  detail partition  select disk 3  detail disk  list partition  select partition 1  detail partition  select partition 2  detail partition  select partition 3  detail partition  select partition 4  detail partition  select disk 4  detail disk  list partition  select disk 5  detail disk  list partition  select disk 6  detail disk  list partition  exit  (post an image of the results into the thread)

Code:

Code:

4) chkdsk /r /v T:  (replace the drive letter T: with the partition drive letter displayed in the result for step 2)  (This may take many hours and typically displays ETA)  (reboot to run the command)  (post an image of the result into the thread)  (reboot after the command completes to check the boot)  (reopen command prompt for the next step)

Code:

Code:

5) dism /image:T:\ /cleanup-image /revertpendingactions  (change the drive letter T: to the drive letter displayed in the result for step #2)  (reboot after the command completes)  (reopen command prompt to run the next command)

Code:

Code:

6) dism /Image:T:\ /Get-Packages  (change the drive letter T: to the drive letter displayed in the results of step #2)  (Run the following command on the last installed package:  example: dism.exe /image:T:\ /remove-package /packagename:Package_for_KB4014329~31bf3856ad364e35~amd64~~10.0.1.0  (change the drive letter T: to the partition drive letter displayed in step #2)  (Reboot)  (perform this command on multiple KB as needed to go back in time to before there were boot problems)

Code:

Code:

7) sfc /scannow /offbootdir=T:\ /offwindir=T:\windows  (change the drive letters T: to the drive letter displayed in result for step #2)  (This command may take a while to run)  (post an image of the results into the thread)  (reboot to check the boot)  (open command prompt for the next step)

Code:

Code:

8) bootrec /fixmbr  9) bootrec /fixboot  10) bootrec /scanos  11) bootrec /rebuildbcd  (post an image of the result into the thread)  (reboot after the command completes to check the boot)

 

Can't boot from DVD drive

Is your controller in RAID/AHCI modes? If so, the DVD drive will be listed as a separate device in the list of available boot devices, not as "CDROM". Remember that when setting boot device priority. Otherwise, read the manual to see which hotkey during POST brings up the boot menu that lets you select which device to boot from. Even here, the drive will be listed separately, and not as "CDROM".
