grub load ubuntu but not windows 7

Thank you for taking the time to report this issue and helping to make Ubuntu better. Examining the information you have given us, this does not appear to be a bug report so we are closing it and converting it to a question in the support tracker. We appreciate the difficulties you are facing, but it would make more sense to raise problems you are having in the support tracker at https://answers.launchpad.net/ubuntu if you are uncertain if they are bugs. For help on reporting bugs, see https://help.ubuntu.com/community/ReportingBugs

Please can you post the output of fdisk -lu

And your /boot/grub/menu.lst please

Are you sure you are using GRUB0.97?
If yes then its a old version. You should first upgrade to GRUB2.
For this go to the page :
https://wiki.ubuntu.com/Grub2
and refer to the "Installing (Ubuntu 9.04+)" section.

This most probably will solve your problem.

If not then post back the error code and on-screen message.

i haven't found the menu.lst, only the grub.cfg(like GRUB2),
this is the output of the fdisk -lu.
It's in italian because i'm italian, so forgive me for my english.

while i was doing the updates, it didn't find the menu.lst, so i accepted to let him create a new one

Where is your windows7 that you are finding unable to boot?
Is it on the same HDD, which is /dev/sda (163.9 GB) or on different HDD(/dev/sdb 250.1 GB)?
Because on both HDD you have NTFS partition.

And please post the contents of /boot/grub/grub.cfg

it's in /dev/sdb 250.1
this is the new menu.lst:
# 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

## password ['--md5'] passwd
# If used in the first section of a menu file, disable all interactive editing

add 'makeactive' in the file /etc/grub.d/30_os-prober and then try rebooting.
If you dont know where to add then please provide the content of it.

Moreover just to verify, can you check which GRUB is actually being used by command :
sudo grub-install -v
moreover can you provide output of :
sudo blkid

Moreover the entry in /etc/grub.d/30_os-prober should be
set root=(hd1)
and not (hd1,1)

If you can also post the /boot/grub/device.map file content, it will be helpful.

just fix your booting with windows 7 DVD, when you boot from it ..just repair and then select first option fix boot problem and then let windows 7 OS repair the booting after the repairing it will reboot thereafter your grub will be behaving properly...
I faced the same problem and this is the easiest way out.
