    What are they useful for ?

    I have never dealt with something like this before.

    They are useful for me .

    If you want to have it on a key, e.g. F9 and not interrupting your startup by being on the visible boot menu, use visualbcd.

    Great program. Looks complicated at first, but it isn't really.

    D/l it from here: 0.9.3.1

    Select New > Custom Actions

    Click image for larger version


    Select Macrium in the bottom dropdown, and whatever F key you want in the top dropdown. Then click ADD.

    Click image for larger version


    Now it will be on F9 at startup. But it is still on the boot menu.

    Remove it from the menu by highlighting bootmgr in the left pane, then click Display order.

    Select macrium and delete.

    Might be an oem protective mechanism. They sometimes do that to be a pain.

    You can do it with bcdedit. The purpose of using visualbcd is to find out if you already have custom actions.

    They must be sequential. 0x54000001 0x54000002 etc. If you don't already have any, then start with 0x54000001

    bcdedit -set {bootmgr} custom:0x54000001 {loader-guid}
    bcdedit -set {bootmgr} customactions 0x10000SCANCODE0001 0x54000001

    your loader-guid is {6670c44c-83b0-11e3-beae-eca86bae535c}and scancode for F9 is 4300

    bcdedit -set {bootmgr} custom:0x54000001 {6670c44c-83b0-11e3-beae-eca86bae535c}
    bcdedit -set {bootmgr} customactions 0x1000043000001 0x54000001

    I appreciate your efforts but I'm really not interested in an F KEY.

    Someone here might though.

    I would give you a rep but I have to spread some around first.

    Yes, it is tricky with an oem machine. That may be why macrium doesn't bother and just adds a simple boot menu entry.

    The boot menu option works good & you can easily remove it.

    I leave it on all the time because I never know when my computer will go haywire.

    I use BootUI tuner from Winaero also.

    It works good too.

    This thread has taught me something about human nature.
    I like learning new stuff.

    It gives me a guideline of how to do things in the future.

    This is interesting. Would you share the things it taught you. When I posted my little problem, I did not think the thread would have such a success - and longh after my problem was solved.

    It doesn't substitute for external media - that is always needed just in case. Access from boot menu can be an extra convenience.

    I just made the standard macrium winpe thing on my machine. It doesn't seem to offer to add a menu option. Is it hidden somewhere?

    No biggie, if you know where the wim and sdi are, can be added to boot display menu without any trouble. ( Hotkey is better, but more difficult to do. )
