help to edit grub.lst

[pregoeater]

im about to edit my grb.lst but before i do that i have a few question when i first instaled ubuntu it give me 3 choices unbuntu,ubuntu revory mode, and memtest. then win xp then next time i did a reboot it added two more that look like the first 2. would anyone recomend deleting them or should i keep then all or can i just REM them? what i would like to do is set it up so there are two thing on the list xp and ubuntu and shorten them time before it selects the os but if i ever need the recovery mode can i still use it if its off the list...here is my list file

The first one is your latest kernel so you want to keep that. The next entry is the recovery mode using the latest kernel so you want to keep that as well in case you need to boot your machine into recovery mode. The third entry is your old kernel so you want to keep that in case there is something wrong with the new kernel. Then, you can remove everything else after that except your XP... To edit your /boot/grub/menu.lst, open a terminal, Applications -> Accessories -> Terminal, and type

gksudo gedit /boot/grub/menu.lst

As long as you back up the file first

sudo cp /boot/grub/menu.lst /boot/grub/menu.lst.backup

and you have live CD, you can do whatever you want to the entries.

If a line has a # at the front of it, then GRUB ignores it. This is called a comment. If someone tells you to comment something out, you just put a # there.

Instead of removing the entries you don't need, might I suggest commenting them out? That way, if you need them again, you can just uncomment them and they will be back.

What are you talking about when you say true / false? If you are referring this line

# memtest86=true

I think it means "when updating GRUB, should I include memtest entries?

**wow, I got beat twice.

It's listed before the example that you gave.
it says

IE: "Timeout 10"

10 being the seconds, so you can put 15 sec, or how many seconds you want/need.


I'm working now, so I don't have a menu.lst to copy from. I'm sorry.

[bulldog]

Edit this in menu.lst,

## timeout sec
# Set a timeout, in SEC seconds, before automatically booting the default entry
# (normally the first entry defined).
timeout 10

Where you can alter 10 to what you want,but don't set it to zero [0] because you can't choose anything anymore.
