I have Windows 8.1, Ubuntu 14.04.2 and Ubuntu 14.10 on my machine. After installing the last, the GRUB is not showing the first two Operation Systems. I have try to fix this using Boot Repair but the Recommended Repair option did not fix the issue.

I have generated a Boot-info Summary since using advanced options of Boot Repair without understanding them could cause more problems.

Here is the full report and here is the initial part of it:

if you have a way to access at least one Ubuntu installation, the answer goes as follows:
1. log in using Ubuntu intallation
2. sudo apt-get update && sudo apt-get dist-upgrade
3. grub-install
4. update-grub
