Windows 10: Inaccessible boot device after I let my friend update my drivers

I don’t know much about computers, but my buddy told me he’d update my drivers for me since I’ve never done that. So I let him and after the restart my laptop keeps going to a blue screen and says inaccessible boot device. We tried the automatic repair and doing a system repair, but both failed and if I try to turn it on it just keeps going to the blue screen with that message and then keeps taking me to a screen with all the options like system restore and command prompt. Should I take it somewhere to get it fixed or can I fix it myself?

Inaccessible boot device

This is a Microsoft link on inaccessible boot device:
https://docs.microsoft.com/en-us/win...le-boot-device

It is an intermediate level link.
There are more advanced steps that can be ran once the partition structure is known.
There are steps for repair of the boot sector, operating system, etc.
Sometimes this bugcheck can be caused by windows updates.

A reset save files equivalent may be able to be performed.
Alternatively a clean install can be performed once important files are backed up.

 

INACCESSIBLE BOOT DEVICE after Win10 Update

1) Find a flash drive that you can format ( > or = 8 GB)
2) Create a bootable windows 10 iso:
Download Windows 10
4) Insert the flash drive into any USB port
5) Open the BIOS and temporarily change boot order so that you can boot using the flash drive.
6) When the iso loads choose language, time, currency, and keyboard, or click next
7) In the left lower corner click "repair your computer"
8) Click troubleshoot
9) Click command prompt
This should open: Administrator: X:\Windows\system32\cmd.exe > X:\Sources>

For all of the steps please use a camera or smart phone camera to take pictures and post images into the thread.

10) type: bcdedit | find "osdevice"
11) This may display osdevice partition=C:
12) type: diskpart
13) type: list disk
14) type: list volume
15) look under the column heading Fs for any volume that displayed RAW instead of NTFS
16) type: chkdsk /f /r G: (change G to the drive letter of the volume displaying RAW)
It may display "The first NTFS boot sector is unreadable or corrupt."
This may then convert the RAW volume to NTFS.
17) Type: exit
18) reboot to open the Windows advanced troubleshooting menu > command prompt > Administrator: X:\windows\system32\cmd.exe > X:\Sources>
19) type: bootrec /rebuildbcd
It may display:
Scanning all disks for Windows installations.
Please wait, since this may take a while...
Successfully scanned Windows installations.
Total identified Windows installations: 1
[1] D:\Windows
Add installation to boot list? Yes(Y)/No(N)/ALL(A):
20) Type: Y
The operation completed successfully.
X:\Windows>
21) Type: exit
22) reboot
See if the inaccessible boot device problem was fixed.

If the above did not fix the inaccessible boot device the next step is to remove the recent update:
23) Open command prompt > Administrator: X:\Windows\system32\cmd.exe > X:\Sources>
24) From the first command displaying the partition if the drive letter is different than C: please use the displayed drive letter for the next step
25) type: DISM /image:G:\ /cleanup-image /revertpendingactions (change G to the applicable drive letter)
26) This should remove the latest update and fix the inaccessible boot device.
27) If this does not fix the inaccessible boot device plan a registry repair.

Report into the thread your progress with images of the above steps.
