View Full Version : [ubuntu] Yet another Windows 7 and GRUB thread.



Mr Connolly
November 1st, 2009, 07:18 PM
Installed Windows 7, had Ubuntu only before. Restored GRUB. Can't get GRUB to recognise Windows 7 - just flickers at me then goes back to the GRUB straight away when I choose my Windows 7 option.

Provided below are my GRUB, boot info script results and my fdisk. If anybody can help me out here you will earn my eternal love. Thanks.

First off, let me give you the helpful parts;





# 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 use 'savedefault' 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 3

## hiddenmenu
# Hides the menu by default (press ESC to see the menu)
hiddenmenu

# 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/

Grub starts counting from zero. Try editing the above line to reflect:

(hd0,1)

To edit the menu.lst, open terminal and type


gksudo gedit /boot/grub/menu.lst

For old grub with menu.lst the entry is rootnoverify for Vista or Win7. Root worked for XP. Also since you have the boot flag on (*) in fdisk listing you do not need the makeactive line.

If you have changed to grub2 there is no menu.lst. A file grub.cfg is built like the automagic area in old grub.
