    how to repair windows boot


    I ticked neogrub bootloader in EasyBCD, thus the opiton "Windows 7" is disabled, as shown in the pic below. Then I reboot the system and now I can't enter windows 7, what can I do? thanks!

    my grub info:
    http://paste.ubuntu.com/8210235/


    I see some solutions, like
    linux - Boot windows from grub rescue command prompt - Unix & Linux Stack Exchange

    where it says

    Code:
    sudo lilo -M /dev/sda mbr
    should work, but i dont' know what is /dev/sda

    is it the partition where my windows 7 is installed (I mean C drive)?
    then it should be /dev/sda1

    but in my ubuntu it is /media/esolve
    should I mount /media/esolve to /dev/sda1
    and then run
    Code:
    sudo lilo -M /dev/sda1 mbr
    ?

    I tried the solutions in this link:
    http://askubuntu.com/questions/13527...dows-partition

    but the solutions seem not work:

    1 it seems my grub info is even more messy:

    Code:
    => Grub2 (v1.99) is installed in the MBR of /dev/sda and looks at sector 1 of 
        the same hard drive for core.img. core.img is at this location and looks 
        in partition 112 for .
    2 F8 doesn't bring me the advanced options

    With classic linux set up /dev/sda is the hard drive and /dev/sda1, /dev/sda2, /dev/sda3 are the partitions on it. the bootloader is usually installed to sda or the master boot record of the drive.

    From the picture you show, Windows 7 is merely not the default. It is NOT disabled and should be able to be chosen when the boot menu comes up.
    Perhaps enable the "wait for user selection" option?

    the issue is that I can not enter Windows 7

    there is an item "windows 7" after rebooting, but when I click it , it redirects to a grub interface

    You can't fix this from GrUB, the issue is with the BCD file on the Windows partition, you will need to repair it first. If you have a Windows 7 installation disk, insert it and select 'Repair My Computer'. All going well it should fix it automatically but if not it will have to be done from the command prompt, see this link
    https://neosmart.net/wiki/recovering...ws-bootloader/
    If you don't have a disk, you can get one here
    How to Use Windows Boot, Repair, Rescue and Startup CDs and USB Flash Drives
    Once back in Windows you can open Easy BCD & correct your error

    Hope this helps
