Windows Cannot complete the installation in Safe Mode.

Hello,

on AIO Optiplex 5250 with Windows10 got a startup repair that would not go away. None of the options as: repair/refresh/reset your PC did not work. Tried to boot into a safe mode using GUI from troubleshooting tab and each time it came back to startup repair/diagnosis window and unable to boot into OS.

The only function that worked was FACTORY IMAGE, however after completing a rollout back now on a start up it says that cannot proceed as PC is in a safe mode.

A question is quite simple: how can I launch the cmd(or troubleshooting) during the boot or prior I get this error below?

Once I have cmd I can execute:  bcdedit /deletevalue {default} safeboot to disable safe mode and proceed with a factory image.

I've already tried all the F8/SHIFT+F8/F10/SHIFT+F10 variations and none of them is working, due to UEFI and not a legacy boot. Is it possible to launch a troubleshooting/startup settings/cmd now at this stage without having an installation media?

"Windows Cannot complete the installation in Safe Mode. To Continue installing Windows, restart the computer."

RE: Windows Cannot complete the installation in Safe Mode.

You can't override this. Have you checked for a hardware problem like a failing hard drive? Run the Diagnostics. Run the complete extended hard drive test. If the hardware is OK. Download the Create Media tool, select make media for another computer,  download your version of win 10, boot to the disk or thumb drive you make and select Custom install, delete the windows partition and install a fresh copy. You will lose everything so make copies of all files. Skip entering a product code when asked. The first time you connect to Internet your digital license will reactive windows.

Thanks Mary G. But if there was a way to enter into a safe mode there really should be a way to exit that and let factory image to proceed. Of course that's perhaps more related to windows/bios logic but still thinking that Dell might have some "hidden" keyboard shortcuts for a workaround. Diagnostic test was done and 0 faults found.

RE: Windows Cannot complete the installation in Safe Mode.

Hi, I had exactly the same problem on a Dell Alienware Alpha and I solved it like this:

When you get the error message:

1. Shift-F10 brings up the command prompt

2. Type msconfig at the cmd prompt

3. You can can now disable the safe boot option on the second tab

You will not have use of the mouse so use tab to move around the form, use the arrow key to select options. You will work out the keyboard shortcuts to navigate eventually.

Tab to the boot tab, tab to the safe mode tick box, use the arrow to select the option and space to turn it of. Tab to the apply. Tab to OK. Press return and reboot.

Worked for me.

Hope this is useful for others,
