Ubuntu – Boot loading problem after Wubi installation of Ubuntu 12.04 on Windows 7

bootloadergrub2windowswubi

I was new in Ubuntu OS and I was just trying to use wubi windows installer to get a Ubuntu first for hands-on.

I followed exactly the same as the instructions and after reboot win7, there is no Ubuntu selection in windows boot manager, with only Windows 7 showing there evilly -.-

What I've found out was that the grub folder inside Ubuntu folder ( in my C:\ drive) was empty, either inside the ubuntu\disks\grub or ubuntu\install\grub. I thought this might be the reason why I could not load ubuntu during startup.

Cause I've also looked into the EasyBCD settings, and ubuntu entry with Bootloader Path: \ubuntu\winboot\wubildr.mbr was lying there peacefully, looking perfectly fine. However it was not in boot loader actually.

Is there a way to restore the grub folder with grub2, or is there any way to fix this problem so that I can find the "Ubuntu" selection at windows startup?

Very appreciate your help 🙂

Run a live Ubuntu CD/USB.Mount the drive where you installed Ubuntu.Run terminal and type sudo update-grub and reboot.If you still stuck with grub issue,come back again to live,type this command sudo install-grub /dev/sda where sda is the drive where Ubuntu lies.Then sudo update-grub and reboot.More info here.
