    Cannot boot into UEFI BIOS or Boot Menu

    Belarc reports UEFI: American Megatrends Inc. P11-B2
    Operating System: Windows 10 Home (x64) Version 1511 (build 10586.494)
    Installed: 4/27/2016 5:58:22 AM Servicing Branch: Current Branch (CB)
    Boot Mode: UEFI with successful Secure Boot.

    This is my brotherís computer: originally it was Win8, upgraded to Win8.1 and then in Apr to Win10.
    --- The computer runs OK and Iíve shown him how to use MRF to create system image backups.
    --- Today Aug 8 we tried to test recovering yesterdayís Aug 7 system image backup.
    --- It didnít go well at all.
    --- The MR recovery DVD-RW didnít boot up in order to test it.

    I thought of disabling Secure Boot to see if that was blocking the MR bootable Rescue DVD-RW.

    However we werenít able to boot into either the UEFI BIOS or Boot Menu.
    --- According to our notes DEL is used to boot into the UEFI BIOS and F12 is for the Boot Menu.
    --- However when booting up: in less than a split second something scrolls up but the computer immediately boots into Windows to log in.
    --- Thatís much too fast to get into the UEFI BIOS or Boot Menu.
    --- Please help us figure out what to do.

    Following that Iíll have to learn how to ensure proper system image backups and recovery using MRF.
    --- I donít recall any issues when I had Win7 but re-training myself makes sense to me because itís obvious I donít understand it well.
    --- For now Iím going to completely uninstall MRF from his computer and hope to start over with a clean slate.

    Try F2 or F8 while Powering ON.. (which you might already Have). If no go update BIOS(which you might already have).

    Assuming you have Windows 10 or Windows 8.1 on computer.. Do a Shift + Restart >> Troubleshoot >> Advanced Options >> Change UEFI firmware settings...Restart.
    U should be be able to boot in BIOS.

    Does the support documentation give any info on creating the bootable DVD? Were there any choice when you created the DVD as to how it would be used or what configuration it should be? There should be something in the paperwork mentioning whether the DVD would be secure boot capable.

    I have not used Macrium Reflect Free so I have no experience with creating the DVD.

    Win 10 starts very fast and can bypass some of the normal Bios startup processes. You need to start tapping the required key as soon as it starts to boot and keep tapping, the earlier the better. You may also see a difference between a restart and a boot from a powered down condition. Or you could do as the others point out.

    Hi there

    The whole purpose of SECURE BOOT is to PREVENT booting of what Ms deems to be unofficial - i.e Non Ms OS'es so a lot of 3rd party boot rescue disks and Linux distros won't boot.

    Simply DISABLE secure boot -- leave UEFI though --and then you can select as normal a Boot option in BIOS.

    Secure Boot IMO was one of the most BOVINE things ever added to computers --it IMO serves absolutely ZERO useful purpose since

    a) Those who don't know how to switch it off are never likely do do anything with their computers anyway so won't be re-installing Windows etc.

    b) those that do install Windows / rescue media etc will switch it off in any case.

    c) it's just a major irritant -- some people actually buy Laptops and run Linux etc as primary OS - not everybody always runs Windows on their machines as the main OS.

    I for example have two laptops running CENTOS 7 as my main OS and have Windows 10 running as a Virtual Machine on these using VMWARE WORKSTATION.

    I need Windows for Office and a host of corporate Software and access to corporate servers.

    d) If you dual boot -- a PAIN.

    Although my issue to access the UEFI BIOS is solved from within Windows is solved what isn't solved yet is to access the UEFI BIOS during boot up using the appropriate DEL key something scrolls up much too quickly and the computer still boots up normally even with Secure Boot disabled. Unfortunately I don't have time to troubleshoot that issue at this time and will make it another thread when I can get back on it.

    EDIT: It was pretty easy to figure out how to access UEFI during boot up when I realized all I hade to do is follow mannish9009ís instructions in post 2:
    ďShift + Restart > Troubleshoot > Advanced Options > Change UEFI firmware settings...Restart.Ē
    Issue solved.
