    Window Boot Manager Issue - Will not boot without selecting F12


    Greetings y'all!

    My title is my BLUF (bottom-line up front). If this belongs in a different sub-section of the forum, sorry in advance.

    I just did a clean install of 10 Pro from a UEFI formatted thumb drive, using RUFUS - did that because I upgraded to a PNY CS2211 480GB SSD. Everything works great once loaded!

    The problem seems to be my laptop can't use the Windows Boot Manager my laptop is pointing to in UEFI settings. I first noticed the problem while installing it (after initial reboot during install). When I hit F12 for the One-Time boot menu and select WBM, it boots just fine - no issue.

    Maybe this has everything to do with the fact I did not make the change prior to install from Legacy to UEFI?

    Very likely, I think.

    The victim is a Dell Latitude E6510, circa 2010-ish. BIOS is up to date (A16 version) and all other drivers/updates are good.

    Appreciate any help rendered!

    Ian

    If the hard drive is set as the first boot device in bios, it won' boot to anything else without using boot options...

  3. Windows 10 installation hangs at "CD Rom boot priority boot ready" screen

    I think I fixed my issue. I pressed F12 to enter boot option menu and selected HDD, pressed Enter and it booted to the Upgrading Windows screen.
