I am facing an issue when I did following. Initially my pc had Windows 7 ultimate x64 installed. Then I made it dual boot with Ubuntu 12.04 x64. Everything used to work fine then.

Problem started when I upgraded Windows 7 to Windows 8 pro. After my upgrade I list grub loader. I was not getting any option to select OS. Then I googled the issue and somehow I do not remember exactly how, I fixed that issue. I am now getting OS option at boot time.

However sometimes usually after installing any updates in Ubuntu I do not see grub loader at boot. Sometimes it appears sometime is does not. I have figured out that this usually happens after Ubuntu update. To fix that issue I run boot-repair and repair system with recommended button. This solves the issue temporarily until Ubuntu update.

By ubuntu update I do not mean Ubuntu version upgrade, update means the security fixes and kind of stuff.

My recent boot repair log can be found at: http://paste.ubuntu.com/5666240/

I am not that much technically familiar with linux machines so any advice will be appreciated.

Does it happen after any package update or just kernel updates? By the way, you have lots of kernels installed, it's fine to remove the older ones. –  grimpitch May 15 '13 at 2:29

  1. Via Windows tools, reduce your Windows partition from 75 to 74GB
  2. Create a separate /boot partition in the 1GB free space as follow: https://help.ubuntu.com/community/BootPartition

hi, i formatted newly created drive with ext4 fs, then it was visible and I successfully relocated Grub loader. It also cleared old kernels :) that worked it seems, thanks –  Calvin Jun 3 '13 at 4:36
