How to set Grub not to auto boot any OS without Grub Boot menu shown
After I installed Ubuntu Dapper by Live CD, I almost could not get into my Windows XP Professional. Then I attempted to add in and success.However, I must press Esc button before I could select Windows XP to boot. I use both OS almost same frequency and I wish to see the OS select menu without pressing Esc. How should I do for such thing to happen?
Note:I heard other people system that not required to press Esc to have a Grub Menu shown. Why can't mine?
and set it to a high number (XX is the time in seconds... I think there should be a way to get it to never automatically boot but I don't know how, setting it to 3600 should be enough ).

Too bad that grub.conf does not exist.
However, menu.lst in /boot/grub (Full location is /boot/grub/menu.lst of course!)can also do the same motive and add Windows onto the list.
This is done by
Quote:
# menu.lst - See: grub(8), info grub, update-grub(8)
# grub-install(8), grub-floppy(8),
# grub-md5-crypt, /usr/share/doc/grub
# and /usr/share/doc/grub-doc/.
## default num
# Set the default entry to the entry number NUM. Numbering starts from 0, and
# the entry number 0 is the default if the command is not used.
#
# You can specify 'saved' instead of a number. In this case, the default entry
# is the entry saved with the command 'savedefault'.
# WARNING: If you are using dmraid do not change this entry to 'saved' or your
# array will desync and will not let you boot your system.
default 0
## timeout sec
# Set a timeout, in SEC seconds, before automatically booting the default entry
# (normally the first entry defined).
timeout 60
## hiddenmenu # Hides the menu by default (press ESC to see the menu)
unhiddenmenu
# Pretty colours
#color cyan/blue white/blue
## password ['--md5'] passwd
# If used in the first section of a menu file, disable all interactive editing
# control (menu entry editor and command-line) and entries protected by the
# command 'lock'
# e.g. password topsecret
# password --md5 $1$gLhU0/$aW78kHK1QfV3P2b2znUoe/

Where to edit the one in bold to unhidden the menu (To show the menu always without pressing Esc button!) and copy the one in Orange to paste in the one in Yellow Green location shown where the title in the Yellow Green location may change accordingly to the Windows that you are using like changing from # title Windows 95/98/NT/2000 shown above into
title Windows XP Professional
or even title Windows Millennium, or title Windows XP Home or even title Windows Vista Ultimate , depending on each scenario!!.Note: The part shown in red has to be changed on case by case basis. If you are using the first or only 1 hard disk and first partition for Windows SYSTEM, Not any personal files formatted in FAT32/NTFS etc , it should be in (hd0,0) if it is the first hard disk, second partition, it should be (hd0,1) and if it is the second hard disk , first partition , it should be in (hd1,0) etc depending on which configuration you had made.
