How do I boot into Windows from the GRUB rescue menu after deleting the bootloader config?
Question by Daniel Joshua /

My friend had his system dual-booting Ubuntu and Windows 7. As he wanted more space to store data in Windows, he foolishly just deleted the partition. Yeah, I knew that by deleting Ubuntu partition he would lose the Grub config/loader that has the data for booting the OS and I warned him long before. Basically I am looking for someone to please tell me if there is any way to boot into Windows?

I used a Windows Vista reinstall disc to open a command prompt and tried the following:

bootrec.exe /fixmbr
bootrec.exe /fixboot

Then rebooted the system. Still no luck.

Please help me!

    use ubuntu llive cd or any other linux live cd boot into it and reinstall grub
    sudo mount /dev/sda5 /mnt *****Using the linux installation on your hard drive instead of /dev/sda5
    sudo mount –bind /dev /mnt/dev
    sudo mount –bind /proc /mnt/proc
    sudo mount –bind /sys /mnt/sys

    Thanks for all your replies guys.

    I used a Windows Disc to check for the Previous Windows Installation in any Partition and found that there was NO WINDOWS INSTALLED on the PC. WEIRD!!! (Checked using CMD by listing all available partitions)

    Then I installed Windows once again. Many Users have come across this Instance.
    If there is a fix please create an article on Makeuseof.com

    Thank you All

      i think if you boot on linux cd you should have install and uninstall option. I am not sure but you can check it.

      my self used like a year ago disk management to format Ubuntu partition then used EasyBCD to delete ubuntu option in boot screen and restore MBR then used parted magic to format ubuntu free partition to NTFS then extended to Windows space. Sure an updated Makeuseof article will be great.

    Recovering the Windows Bootloader with EasyBCD –

    http://neosmart.net/wiki/display/EBCD/Recovering+the+Windows+Bootloader+with+EasyBCD

    If you want to try last time using Windows DVD,then boot from it and click on Repair,then click on command prompt,type –

    bootsect /nt60 SYS /mbr

    Close the command prompt and restart your PC.

    Source – http://www.askvg.com/how-to-remove-linux-boot-loader-from-startup-after-deleting-linux-partition-on-a-dual-boot-system/

    This will remove Linux Bootloader and will allow you to boot into Windows OS.

      I’d go with the Windows 7 installation disc method. Choose “repair” and let the system do the legwork. Works every time.

    • Daniel Joshua

      Thanks but not working.

      Still I am in the Grub Rescue

    • susendeep dutta

      Then use a Linux live ISO and boot your PC from it.Recover all data from HDD and reinstall the OS you wish to use.
