    Remove grub bootloader /fixmbr and /fixboot not working


    I tried out Ubuntu on a dual boot and i decided dual booting was not working for me, so i'm trying to remove it and get back to normal. So i followed a few tutorials online and deleted the swap and ubuntu partition, and then I make a recovery USB using windows 8's 'Create a Recovery Drive' tool, and then restarted my computer. Upon booting, i was greeted with Grub's command interface. Unsure what to do, i googled it and someone suggested using the exit command and i was brought to a screen where i could choose different devices to boot from, i tried the windows bootloader option, and that worked, I tried the Ubuntu option and that brought me back to the grub command line, and i tried the USB option and that brought me to a recovery screen for windows where it asked me to choose a language just like in the tutorials. The part that is different and i don't understand is on the tutorials, the next screen is always where it gives you an option to install windows 8 or repair windows 8. I don't get that option. For me, it is either troubleshoot or continue to windows 8. In the troubleshoot menu, i found my way into the command prompt just like in the tutorial, and executed
    Code:
    bootrec.exe /fixmbr and bootrec.exe /fixboot
    both of these said they were successful, so i exited out of the command prompt and clicked continue to windows 8. Doing this brought me back to the grub command line. I tried restarting my computer to see if that would work, but it too brought me to the grub command line. What am i doing wrong and how can i fix it? I want grub bootloader gone and for my computer to boot into windows normally.
    Any help or suggestions is greatly appreciated. Thanks.

    Hi there

    Try step 7) in my post here - this explains how to remove Ubuntu from your system

    How to make Portable Windows system (any version)

    Note though if you are using UEFI this might need to be changed a bit. If you have UEFI please post back again.

    Cheers

    It is important to know if you have a UEFI install or Legacy, since they have to be handled differently..

    If it is UEFI, you should be able to set the Windows Boot Manager as First boot device and boot directly into Windows 8. If you have a Legacy install, the Bootrec /nt60 command may help remove the Linux Boot system..

    If you need to remove the Linux boot options, you may have to edit the BCD Store using bcdedit.exe.

    I am having this same exact problem. I ended up, as Saltgrass suggests, going into BIOS and selecting WindowsBootLoader as the first to be executed upon start-up. That certainly seemed to get rid of the problem with entering GRUB every time I start my computer, but GRUB is still there.. Does anyone know if there is a way to actually rid the system of GRUB without completely re-installing windows?

    Yu have to be careful removing this if working with UEFI, it may not configured as it would have been on Windows 7.

    A picture of your Disk Management window might help decide the process needed. You might be able to remove the Grub Boot option using msconfig.exe or by editing the BCD Store.

    Thanks for the replies!
    I am working with UEFI. I have a lenovo laptop with windows 8.1 pre-installed. I had installed Ubuntu next to windows, but I was having some major keyboard and mouse issues that I couldn't seem to resolve.

    You attachment seems to show a normal install, so I would suggest you run the following command and attach the results if you want us to look at it. Removing some of the entries may eliminate the Grub options.

    bcdedit /enum all > %userprofile%\Desktop\bcdtext.txt

    You will probably have entries for Grub and Ubuntu.
