Windows 10: Grub Loader missing

my Dual boot of ubuntu is missing after i installed virtual box in windows 10 so how to get my grub boot up option

:)

 

How do I remove the Linux Boot Loader?

You don't actually uninstall a boot loader but replace it with another.

You cannot get Ubuntu to start on a Windows' boot loader, it needs to be GRUB (or an open source equivalent).

Any ways, to get the Windows' boot loader back up, you need to insert your WIN7 installer disk and select the repair option>startup repair. I am assuming the WIN7 will use a similar setup menu as VISTA.

Follow the guide here for step by step intructions: Fixing the Windows Bootloader via the setup DVD

After that, just format the partition/disk that ubuntu is on...

Starting Problem in Windows 10, grub issue

Thank you for posting back.

This might require fixing the boot record of the partition and the MBR of the disk where the partition is placed. Try this steps to run a repair:

1. Open Command Prompt as admin.
2. Enter (or copy and paste) this command-line.

Code:

bootsect /nt60 drive_letter: /mbr
Replace [i]drive letter[/i] with your actual driver letter.

Example: bootsect /nt60 c: /mbr
