    msconfig changed boot cores from 1 -> 6 memory->8192


    In the boot tab under misconfig I changed the cores used from 1 to 6 and the memory to 8192mb, I clicked apply then restart. Now the computer fails to boot and offers a system restore (which does not work) or 'cancel' which does nothing. Could anyone help?

    No, you have changed the number of used CPUs from 1 to 6 and since you only have 1, Windows became

    I've been using that boot 'speedup' fix for a very long time now. It worked on Windows XP and still works in Windows 10.

    You cannot set a number of cores greater than what is already in your CPU chip. That setting will only show you how many cores you actually have and NO more! I always set it to use the max. number of cores available, but..... I never mess with that memory setting.
    Obviously, messing with that setting and getting it wrong, can BRICK your computer.

    The entire fix for making a PC boot up quicker was written up in a popular web site several years ago and I still have it on file.

    Shorten the Boot Time in XP, Vista & Windows 7 & 8

    Go to the start button, choose run, then type msconfig and press Ok.
    On the system configuration window, choose the "Boot.INI" tab.

    Check “No Gui Boot”, then lower the timeout to a more manageable time.
    I choose 3 seconds in stead of 30. (windows won’t accept a lower number than 3)

    Next choose advanced options.
    This is where you can choose how many processors you have.
    Most modern PC's are duo core (2 processors) with some quad core (4 processors)
    then choose OK. The Windows default is only 1 core.

    Now choose apply and OK, reboot and you should see a marked decrease in boot time, and an Increase in Run-Time efficiency.


    Some Self Proclaimed experts will say that the fix does nothing, but if done right it doesn't hurt either, so I do it anyway.
    It does seem to speed up the Boot-Up process.
    If it can do nothing, then why did the MS programmers include it in very version of Windows since at least Windows XP?

    Cheers mates!

    That's nice but doesn't help OP. I think going to have to try a repair install with an ISO. No image backup?

    Thing is, I made a system restore point a few weeks ago and when I click system restore it just shows the windows logo. Also my cpu has six cores so I have no idea what the problem could be :/

    It's been a few years since I've seen this mentioned, but if memory serves correctly, it is meant to limit the number of cores available for developers to test software and drivers. It has nothing to do with adding any type of performance, as your computer will use the hardware it is given by default. There's absolutely no reason to touch that setting on a normal computer.

    I'm not trying to be an ass here, but you should check into something before taking a jab at "self-proclaimed experts". Yes, I know the type, and there are plenty of people who like to spew "facts" with out checking them, but this one was a simple one to research on Google.

    I think unless you can get into your system with Lunix or Win PE and somehow change that setting. Your Bricked. I'm sorry I have no idea how you would do this. But it is logical since its a windows setting that if you can get in Pre Environment Or Lunix and some how change that setting??? Or at least Clean the disk so that your can start over with a clean install? that's all I can think of. OBTW is you want fast boot put in a fast SSD 10 second boot are common
