How can I edit the boot listing in ubuntu14

Question

I want to hide some of the list from boot menu.Is it possible?

Answer 1

Yes you can:

Here's an example GRUB config file (this is an earlier version of GRUB, but the concept is the same):

default=0
timeout=10
splashimage=(hd0,0)/grub/splash.xpm.gz

# section to load Linux
title Red Hat Enterprise Linux (2.4.21-1.ent)
    root (hd0,0)
    kernel /vmlinuz-2.4.21-1 ro root=/dev/sda2
    initrd /initrd-2.4.21-1.img


# section to load Windows
title Windows
    rootnoverify (hd0,0)
    chainloader +1

To remove the windows option, just comment it out like this:

default=0
timeout=10
splashimage=(hd0,0)/grub/splash.xpm.gz

# section to load Linux
title Red Hat Enterprise Linux (2.4.21-1.ent)
    root (hd0,0)
    kernel /vmlinuz-2.4.21-1 ro root=/dev/sda2
    initrd /initrd-2.4.21-1.img


# section to load Windows
#title Windows
#    rootnoverify (hd0,0)
#    chainloader +1

Make sure to comment out everything underneath that option. They should all be tabbed out one or two, so you can kind of see what's what.
