Hi,
So essentially you want to know if there is a way to make the count down timer disappear so that people can choose from the list of installed OS's. I will do a little looking I believe that it is a simple config file change but I will have to do a little trying on my virtual machine.
Ok, I figured this out. You need to get to the config file for grub. To get to this go to Terminal. To get to Terminal go to Applications -> Accessories -> Terminal. From there you will need to enter this into it.
Code:
cd /boot/grub/
sudo nano menu.lst the l is a lower case L
Next you will see a configuration file. You will need to scroll down the
## timeout sec. Once there look three lines down and you will see
timeout 3. You will need to change that line. To change that line just put a
# in front of the word
timeout. Then you hit
CTRL+O to save the document. Then hit
y for yes, and then
CTRL+X to exit.
Cheers!
