Hello all,
My system specs are the following: Windows 10 Enterprise 64-bit UEFI Bios Phoenix BIOS version and drivers are updated, also confirmed by Slimdrivers. Samsung Series 5 ULTRA 530U4C-S02PT Also: It is an hybrid drive, 1TB HDD & 24GB SSD that is supposedly well installed (the laptop never been so fast after formating and installing windows 10 with express cache to take advantage of SSD hybrid boosting). Windows works like a speedster the only problem is the inaccessibility of BIOS, for example i want to enable the virtualization VT-X to install Oracle VM and i can't go BIOS to edit virtualization.

Problems: UEFI BIOS firmware settings boot dialog is inaccessible.Not working suggested fixes:

  • i) hotkeys Esc, F2, F4, F8 and F10 don't log in BIOS. Although safe mode, debug logging, etc are available. Disabling Fast Bios in the control panel > power management dialog doesn't do anything.
  • ii) automatic repair seems to give an error, after the account is specified in the repair boot dialog it gives error.
  • iii) recovery > Advanced options > UEFI Firmware Settings Boot is not Visible.
  • iv) EasyUEFI free only works with Windows 10 Home, not Enterprise (it would resolve the issue appropriately with the boot into UEFI option) Sources:

Cause (according to internet forums): i) Probably my uefi has Secure Boot Enabled and Fast Boot also, making the boot system almost instantaneous and rendering other boot scenarios blocked. Because system is only seeing the SSD drive as boot option. ii) There is a problem with samsung laptops and uefi, that makes the express cache and SSD install very tedious and difficult, i managed to do it and the pc is smooth the only issue is to access BIOS.
Anyone has a clue on how to sort this out.
