    One last post!

    Can you click on each of the Boot Options, one at a time, and post what the available picks for each Boot Option?

    Thanks,

    Bill

    I don't have a "Boot>Boot" screen. To get the image from BIOS, I explained before. Put in a USB flash drive stick, boot into BIOS, pressing F12 will ask you where to save, it should show the USB stick, click it and OK, it will say the screenshot has been saved. Booting bavck to Windows and opening the USB stick will show the captures.

    It's for choosing which device of that type (HD) to boot first.

    By now its pretty clear UEFI vs Legacy is chosen solely in Boot Device 1,2,3... But it doesn't explain the error during UEFI install for which every other thing was tried.

    Still not clear on difference between Boot Device 1,2,3 and Boot Override menu though. Anyone? Don't you have this board Gary?

    Boot device 1, 2, 3, etc will boot the first bootable device it comes too. Example, you have a bootable CD/DVD in the tray, that will boot before the hard drive. If the tray is empty it will then go to the next in line, e.g. the HDD.

    Boot override allows you to set what device you want to boot at only the next boot up, for example if USB is in P3 and you want it to boot, bypassing the HDD.

    Back by request:

    Beanster, I'm not familiar with the AMI BIOS, so please bear with me.

    In an early post you gave the following information as it relates to Boot:
    P3: ASUS DRW-24B1ST
    JetFlashTranscend 4GB 1100
    P2: M4-CT256M4SSD2
    P1: WDC WD1002FAEX-00Z3AO
    UEFI: JetFlashTranscend 4GB 1100

    I don't know what P1, P2 and P3 signify or how they get assigned, so here's my question.

    If P# get assigned by physical connection (the port the drive is connected to on the Mobo) then
    I'd say that you should swap the SATA ports that the WD and Crucial drives are connected.

    If you can assign the P# in the BIOS, then I think this is the order you want
    P1: M4-CT256M4SSD2
    P2: WDC WD1002FAEX-00Z3AO

    In either case, I believe you want P1: M4 and P2:WD

    I've lost track of the current objective, but at some point... NOT NOW ... it might be advisable to hit that F5 key ... but not just yet.

    Let Greg and Bitton30 think about setting defaults - besides yourself, they have invested the most time.

    I'm offering it as something for everyone to consider, not an action item.

    The P is for boot priority Position. P1 first in boot order, P2 second, etc. I find the best configuration is as follows:
    P1 CD/DVD drive
    P2 USB if the option is available.
    P3 Drive with the OS

    That allows any bootable media to boot before the OS, say a Linux Live CD.

    Thanks Gary,

    So you're saying that the Priority can be set in BIOS. Good.

    Boot Priority has long been a subject for debate. For "security" purposes and installation reasons, many professionals call for the HD to be first, followed by the OD, and then the flash. Using the Priority nomenclature:
    P1: OS
    P2: Optical Drive
    P3: USB

    I don't buy the security reasons (someone can always hit the Fkey and get to the Boot Order menu), but installation reasons makes sense. P2 and P3 could be switched around, it depends on the media you use most.

    @Beanster: any chance you could comply with post# 82? I think it got buried along the way, but I'd still like to see what's under the covers on the screen in post# 81. Thanks.

    Bill

    Is there a one-time BIOS Boot Menu key? Doesn't it show every bootable device? Why the override then? Just askin.
