Upgrading from 10.?? to 11.04 destroyed Win7 Dual Boot. Recover?

[pwright2]

My netbook was set up to dual Boot Win7 and Kubuntu 10.something. Kubuntu was installed into its own partitions, not a WUBI install. I decided to let Kubuntu upgrade itself to 11.04. That seemed to work OK but my machine does not offer to boot into Win7. Is there a simple way to recover?

Sound like an issue with grub...

sudo update-grub

Re: Upgrading from 10.?? to 11.04 destroyed Win7 Dual Boot. Recover?

hm...

Well you might need ti manually put windows back into grub... I'll leave that to someone with a little more experience. It might help to look at your partition table to see where windows is installed
http://www.cyberciti.biz/faq/linux-v...-fdisk-parted/

PS-- I have no idea if it would help, but- have you tried BURG?

Re: Upgrading from 10.?? to 11.04 destroyed Win7 Dual Boot. Recover?

Let's check your boot info first:

cd ~/Downloads
wget [url]http://nchc.dl.sourceforge.net/project/bootinfoscript/bootinfoscript/0.60/boot_info_script060.zip[/url]
unzip boot_info_script060.zip
chmod +x boot_info_script.sh
sudo apt-get install gawk
sudo bash boot_info_script.sh

paste the content of ~/Downloads/RESULTS.txt into your next post.

Re: Upgrading from 10.?? to 11.04 destroyed Win7 Dual Boot. Recover?

That was interesting. About half way thru I realized "hey! I have no idea what these commands are doing!". But I continued on anyhow. Gullible? Perhaps. Needing help? Definitely!

Re: Upgrading from 10.?? to 11.04 destroyed Win7 Dual Boot. Recover?

Somehow GRUB also installed on your RECOVERY partition (sda1), removing /boot folder on sda1 should fix the problem.

sudo mount /dev/sda1 /mnt
sudo rm -r /mnt/boot
sudo umount /mnt
sudo update-grub

NOT A SOLUTION, MAYBE A TEMPORARY WORKAROUND

you may be able to use launch GAG or GRUB4DOS from this CD and get into Windows

Just curious, what bootloader are you currently using now (grub or burg)?

Anyway you can try reinstalling grub, type exactly as shown below:

sudo mount /dev/sda7 /mnt
sudo grub-install --root-directory=/mnt/ /dev/sda
sudo reboot
sudo update-grub

[pwright2]

Re: Upgrading from 10.?? to 11.04 destroyed Win7 Dual Boot. Recover?

Ummmm, well. After the sudo reboot executed the machine appeared to do a reboot but now it stops at a black screen reading:

error: file not found.
grub rescue> _

and the flashing cursor line, of course.

Anxiously awaiting guidance.

-----Paul-----

[pwright2]

Re: Upgrading from 10.?? to 11.04 destroyed Win7 Dual Boot. Recover?

Did a little reading on grub rescue. Perhaps some of this will be significant. Response to the 'set' command is:

prefix=(hd0,msdos7)/mnt/boot/grub
root=hd0,msdos7

ls /boot returns 5 lines of file and folder names. burg/ is one of them. Several vmlinuz and initrd.img entries.

insmod linux gives file not found

insmod normal gives file not found

-----Paul-----

[ubuntuku]

Re: Upgrading from 10.?? to 11.04 destroyed Win7 Dual Boot. Recover?

Please run the below commands:

set prefix=(hd0,7)/boot/grub
set root=(hd0,7)
insmod normal
normal

The GRUB menu should appear now.

Re: Upgrading from 10.?? to 11.04 destroyed Win7 Dual Boot. Recover?

Anyway you can try reinstalling grub, type exactly as shown below:

sudo mount /dev/sda7 /mnt
sudo grub-install --root-directory=/mnt/ /dev/sda
sudo reboot
sudo update-grub

Sorry for the trouble, somehow I forgot to mention that these should be done from a live cd . So now please boot to the kubuntu natty live cd (select start kubuntu, don't install it!), Once you boot to the live cd, open konsole and run the above commands.
