    win 10 pro 64bit

    Win 10 pro 64 bit updated, now wont boot...something wrong with mbr

    So after updating to the anniversary edition I cannot load the OS. I have downloaded a couple of different versions of windows 10 and burned them to dvd and usb. Tried to repair and re-install even, but can't even do that! I cannot fix the problem. I have it installed on an ssd, been installed for over a year without any problems. Any Ideas? I am using a bootable usb with windows PESEX64 to type this up. Tried using the various tools in this to no avail. I can see the partitions and they seem healthy...what gives? please help!

    On another pc, install Macrium Reflect Free and create a Rescue drive.

    Boot from Rescue Drive and select restore tab.

    Click on fix "windows boot problems"

    It should list windows 10. If so click next, finish and with luck PC will now boot.

    This may or may not be the cause. But if you manage to get into windows even in safe mode. You may want to try disabling fast boot. I have 2 systems relatively the exact same specs other than the CPU & 1 has problems with fast boot enabled & the other does not.

    To disable this

    • Type Control Panel in the search box.
    • Click Control Panel.
    • Click Power Options.
    • Click Choose what the power buttons do.
    • Click Change settings that are currently unavailable.
    • Scroll down to Shutdown settings and uncheck Turn on fast startup.
    • Click Save changes.

    This is more of a problem with older laptops but does effect modern systems too.

    Windows 7 Ultimate, Windows 10 Pro AU 1607, Linux Mint 17.4, Ubuntu 15.04 LTS

    One thing to try is at "power on" tap the F12 key which should list the various drives connected and allows you to select a temporary boot device. Select your ssd as the boot device. In the past I have had a similar problem and found that the system was trying to boot from the wrong device.
    If the system boots, the BIOS boot order needs to be reset or if F12 does not work check the BIOS boot order anyway.
