Unknown Hard Error

Hi All,

I have been trying to resolve various issues with W10 (see other posts) and have been trying to use Safe mode to rule out possible configuration abnormalities.


However, on both of my test machines, I get an error dialog titled:
explorer.exe - System Warning
with the content showing a yellow triangle and the wording Unknown Hard Error
... preventing me getting into Safe mode.

here's a pic (note I have moved the dialog to show the start button in the same view)
Attachment 12082

Any clues?

As I said, this happens on both machines; one is a Dell 9150 desktop and the other a dell E6520 laptop. Other than this problem, the E6520 works fine in normal mode, although the desktop has other problems with an explorer crash/restart loop at startup.

Thanks

This works on W10 RTM so worth a try. you can copy paste the following which will give you the F8 Boot Menu Option to obtain Safe Mode at startup.

From an elevated command prompt type> bcdedit /set {default} bootmenupolicy legacy
From an elevated command prompt type> bcdedit /set {bootmgr} displaybootmenu True

The post you replied to was a year old and on an early test version. One hopes problem has been solved by now! :)

Utters post 2 hours before mine obviously threw me as to the original thread opening date.
Hopefully my response to Utters post solved his problem.

click restart while holding shift then click on troubleshot then click reset thats how i fixed my error

Has anyone ever solved this issue I know the thread is old from 2015 but it is 2021 and I am facing this issue on my Windows 10 Professional 21H1 as well. Any solution guys ??
