So here's the thing, I recently installed Ubuntu 14. Everything works fine except the boot loader. I currently have windows 7 installed on another hard drive. But when I boot the machine I get a black screen with a purple border, and then it boots directly into Ubuntu. I tried re installing grub 2 and loading the boot repair but neither worked.
You can press the Shift key after the manufacturer screen and before ubuntu boots... Got to have good timing. You could also edit your /etc/default/grub and put a # in front of the GRUB_HIDDEN_TIMEOUT line. Then run sudo update-grub to complete the change. Go to a terminal prompt.
sudo nano /etc/default/grub
- Make comment out the line that says GRUB_HIDDEN_TIMEOUT=0 with a # in front of it.
- hit control-O (the letter) and enter to save
- hit control-x update-to exit
sudo update-grub(to make the changes)
You might also be interested in Grub Customizer. It allows you to easily put backgrounds, change default operating system and the timeouts.
Go to a prompt..
sudo add-apt-repository ppa:danielrichter2007/grub-customizer
sudo apt-get update
sudo apt-get install grub-customizer
Now you might want to use boot repair..
sudo add-apt-repository ppa:yannubuntu/boot-repair sudo sh -c "sed -i 's/trustysudo apt-get install -y boot-repair/saucy/g' /etc/apt/sources.list.d/yannubuntu-boot-repair-trusty.list" sudo apt-get update sudo apt-get install -y boot-repair
