Windows 10: Cannot enter advanced option mode

Hello, I just experienced an issue with my Lenovo laptop. I last used it about 2 month ago June 2022 when I had to do some stuff for university. I’m pretty sure that I turned the laptop off making a win10 update and now I get the blue screen error with the code inaccessible boot device… I looked up possible solutions and It seemed easy to solve by entering the advanced option mode but I’m somehow not able to get access to this mode… I tried using the method where I restart the device multiple times but I’m not able to get access to the mode. What am I doing wrong or are there other ways to g

Cannot Enter Safe Mode / Computer boots normally

I'm running Win 10 Pro 1903.

Here are the steps I have taken to get into safe mode: Start button, settings, update and security, recovery, advanced startup, troubleshoot, advanced options, startup settings, restart. The computer boots normally, not in safe mode. Any suggestions would be most helpful. Thanks in advance for your help and interest. .

 

No Advanced Restart Options

I solved it. I entered these commands. Reagentc reported it was already enabled but the Advanced Boot options now appear.

1. diskpart
2. select disk 0
3. select partition 1
4. assign letter=R
5. exit
6. reagentc.exe /setreimage /path R:\Recovery\WindowsRE /target C:\windows

 

Windows 10 BSOD with mouse; no option to boot to SAFE MODE in Advanced Options

I clicked the link to read the suggestions for getting into Safe Mode. I can do none of those. I have no installation media and I cannot log into Windows to perform the other two suggestions.

When I go into recovery mode, there is NO Startup Settings listed in Advanced Options. INstead, it is an option to get into the bios (which I have done, I did change the screen (??) settings to boot only to the LCD, not automatic or external. I did not
change the boot order as I have no boot disk or usb for Windows 10). (I read in another post that sometimes a dual video boot occurs and confuses the computer, however, changing this from automatic did not solve the problem)

Neither can I get into msconfig from the command prompt. I can get into Regedit, but can't find the video drivers to rollback, no . (assuming it IS the video drivers that are causing this problem.)

This is very frustrating. I will try to upgrade by buring the ISO file through another computer and reinstalling on the affected computer.
