I cannot start Windows 10 Pro x64 with Roccat keyboard and mouse connected. In safe mode, Windows starts correctly. When I unplug the mouse or keyboard, Windows will start up.

I will add that it is a Lenovo y510p laptop. The laptop's bios is very limited. I only have these options in BIOS:

I can't do much with this BIOS. In safe mode, the laptop boots normally but why?

Models: Roccat Vulcan Aimo 121, Roccat Kova

By "does not start", what I mean is that Windows won't start with Roccat's mouse and keyboard plugged in. It stays loading Windows with that spinning white circle

I found out what is the reason why windows do not start correctly. The problem is the sd card plugged into the laptop. When I remove the sd card, windows starts up properly

    So start by updating UEFI. Then you may want to try disabling Fast Boot (UEFI setting). Jul 1 at 9:14
  • What model are the roccat keyboard and mouse?

  • Change the boot order in the BIOS by putting your hard drive to the top of the boot list. It sounds like you have USB devices higher up in the boot order instead.

    @ All Keep in mind that if safe mode works, the boot sequence and everything is perfectly fine. // @nivenNo You might want to try the Boot Log feature. It might help you identify the problem.

These devices often have a little bit of storage onboard that the computer detects. This often pops up as a drive in explorer with drivers and settings placed on them.

If your windows is not set to boot from the Windows Bootloader, these drives may appear higher in the list.

All you need to do is enter the UEFI setup and set the bootloader to either Windows Bootloader or the harddisk windows is on incase windows bootloader is already the primary bootloader.

    Often? More like “sometimes” (as in almost never). It’s highly unlikely these would interfere with the boot order, even more so with EFI booting.
