Boot from ubuntu live CD.

Open your linux system volume in root mode and

in that locate the file

/boot/grub/menu.lst

In that change the timeout value in this place as shown below

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

Hope it helped. . .

Else try another shortcut . .

React before boot menu starts up by just holding down arrow key before booting itself ..

I dont know whether it will work or not . .

But first answer will work.

How to open linux system volume in root mode.

Even easier might be to press the "Escape" key just before and around the time the grub menu should appear, there's sometimes a little prompt telling you to try pressing Esc to see the menu. This will give you the menu back and let you into Ubuntu.

I sometimes set this up deliberately to stealth my Ubuntu install. This means i can take my time about sorting out Ubuntu and not scare the machines owner until they and the machine are ready to use Ubuntu

Good luck and regards from

When booting up you first get a splash screen advertising the motherboard in your system then there's some hardware detection of hard-drives, then lots of bios tables then it tries to see if there are other boot devices, such as floppy or Cd's then start pressing Esc not too fast or too often, just be cool and watch for the prompt about pressing Esc.

If it doesn't work then the Windows Screen and bar appear - in which case it's better to let Window fully boot then to hit the reboot button on the machine or else Windows will get grumpy and might even freak out.

Hope this helps!
Good luck and regards from

Lol, i had that too when i first tried a LiveCd :) the menu.lst needs to be the one on the drive not the LiveCd's one! lol. i'm glad someone else has done that too.

From a command-line try

cd /media
ls

that's a lower-case "LS" and tell us what folders are in there? There should be "disk", "disk-1" (also "cdrom" and perhaps others). Try typing

cd /media/disk-1
ls

and this should have your linux folders in, not Windows ones, otherwise try "disk" instead of "disk-1". Now, notice i don't put a / at the front of this ...

cd boot/grub
ls
sudo cp menu.lst menu.lst.140409
ls
sudo gedit menu.lst

Hopefully this should all work now.
Good luck with this
