Installed Ubuntu 12.04 and no Menu on boot!

Solution 1:

Maybe there is a Windows recovery environment (just maybe) and you chose that place as the place to install GBUB.

Whatever reason, follow these steps to restore GRUB.

Keep in mind that it doesn't overwrite the MBR, instead it adds a GRUB entry to the windows Bootloader.

1. Download Easybcd here. It's a tool that can edit the windows bootloader and it is a very popular program along Windows-Ubuntu users.
2. Open EasyBCD.
3. Go to "Add new entry"> Linux/BSD and then select GRUB2 from the dropdown menu. Name the entry whatever you want, like "I love linux" or "Ubuntu GRUB".

That's it! You should see a GRUB entry in the Windows boot menu when you reboot. Select it and choose "Ubuntu generic . . . . . .pae" from the GRUB menu(if the installation failed then you might not see it).

Good Luck!

Solution 2:

It worked for me. I had installed Ubuntu 12.04 alongside Windows 7. But in boot menu there was just Windows 7. By using easyBCD I have it solved and now I have Ubuntu in boot menu. Notice that I wrote Ubuntu 12.04 instead of Ubuntu 10.04 which is seen above.
