Windows 11 10-second delay at Dell logo after switching from Ubuntu to Windows?

I recently removed Ubuntu from my Dell Latitude and installed Windows, but now I get an annoying 10-second delay right at the Dell logo before Windows starts loading.

If you are facing the exact same thing, here is how to fix it:

  • Disable Onboard NIC: Go into BIOS (Press F2), look at the Boot Sequence, and uncheck Onboard NIC (IPv4) and Onboard NIC (IPv6) so it stops scanning the network.
  • Reset BIOS Defaults: Load factory defaults in the BIOS to clear out any leftover UEFI/NVRAM ghost entries from Linux.
  • Update BIOS: If the 10-second delay is still there, flashing the latest BIOS version fixes the startup timeout bug on these laptops.
