    Msconfig/Boot/Advanced/Use maximum memory-now it crashes on bootup


    ...and it BSODs. I can’t figure out how to fix it. System Restore does not work. The problem is that when fiddling around with using maximum amount of memory for bootingin msconfig, it got into a state where it would only allow 256 bytes or less. I should have deselected the maximum memory radio button. The advanced system restore allows a limited command prompt but I needto knowwhat to type at the command line to manually fix it.

    I would have posted this under the BSOD section but the forum software would not allow me to.

    Try restarting the computer into Safe Mode, then running MSCONFIG. You will have administrator privileges when you log into Safe Mode, so perhaps MSCONFIG will let you deselect the maximum memory radio button.

    In the command prompt, type the commands below:

    bcdedit /deletevalue {default} truncatememory

    shutdown /r /t 0

    FYI:     If you're going to mess with system settings, even if you think, or know what your doing, backup (system image) your computer to external storage! Read 2nd line of my footer.

    Happy Computing!

    Thanks!


    That did the trick, although I didn't see the part about shutdown... in my email. I saw it just now here.

    I did have a cloned drive but it is a long story. I am having problems with my ASUS X99-E WS mobo recognizing my Samsung m.2 drive as a boot drive.

    Anyway, in the meantime, before I got your message, I had installed another ssd and loaded Windows 7 on it.

    So, now that I have the BIOS confused as to which SATA port this drive is located on, it takes some rigamarole to boot.

    Thanks


    I have been working with Asus to resolve the problem but finally gave up. The Samsung m.2 drive works fine as a regular drive, but just not as a boot drive.

    Is the BIOS detecting M.2?
    Do you have latest version of BIOS?
    Head over to Sysnative Forums and post your boot issue, in appropriate forum. They are way more knowledgeable than any product tech support ever hoped to be!

    I do have the latest BIOS. The m.2 drive works perfectly. The only thing I can't do is make it into a boot drive. ASUS offered to fix the motherboard in case it was a faulty board but I declined since this is my main computer and I don't want to be without it. I other computers but this is the one that I am using right now.

    Just a couple of things: First don't futz with the memory! Second, if you're in MSCONFIG and want to
    improve performance, change the 30 second delay to 3 seconds. (minimum recognized setting)

    On the matter of the "Shutdown" command, "/t 0" should actually read "/t 1". Because Windows does not recognize a zero as a legitimate value. Using a zero instead of a one will actually slow down the Shutdown process. Go Figure!
    OH, and /r is only for Reboot, /s is for a quick Shutdown. I've been using a shortcut to that command, on my desktop for years, and I get a nice 5 second shutdown. My customers love it too!

    Happy Easter!
