Package: grub2
Severity: important

--- Please enter the report below this line. ---
When I installed grub2 I no longer had my dual boot windows line on the menu.
When I uninstalled grub2 I still don't have the windows boot line even though it
is in the menu.lst. How do I get it back?

grub2 uses grub.cfg not anymore menu.lst
So what do you mean with `uninstalled grub2'? Did you run grub-install
from grub-legacy?
Just installing the grub-legacy package doestn't do this for you.
Anyway update-grub from grub2 should add your Windows if you install
os-prober.

In synaptic I did a mark for complete removal of grub2 which also marks
grub-pc and applied it.
Then I installed grub using synaptic which installs grub-legacy.

I am attaching my menu.lst. The Windows NT/2000/XP no longer shows up
as an option when I boot. Only the kernels in the Debian automagic
kernels list show up.

As I said if you want to have grub2 with your Windows entry then install
os-prober and run update-grub again. Then it should show up again.
It doestn't at all use menu.lst.

If you want to revert to grub-legecy you need to run grub-install again,
so the MBR gets replaced with the grub-legacy bootcode instead of the
grub2.

I installed os-prober and reinstalled grub2 and windows shows up again.
