Cannot boot windows 7 anymore

[fincher1]

I messed up... really badly. I was curious to see what would happen if I deleted the partition ubuntu was on, so I did. Afterwards, I lost the capability to boot windows 7! I tried going into a command line in grub, using:


root (hd2)
chainloader +1
boot

I was informed that the partition was ntfs (so it's windows 7), but when I tried to boot it told me that BOOTMGR was missing. I'm completely new to ubuntu so I have no idea what to do at this point. I tried opening the menu file for grub, but it's got nothing in it for some reason (I'm obviously doing something wrong here haha).

Here is my boot info:

Thanks for your help in advance, everyone.:)

[fincher1]

Sorry, I forgot to mention this. I installed Windows 7 first and ubuntu second. Not sure if this is important or not, but I figure it doesn't hurt to mention it. :)

[Quackers]

As Ubuntu is still on sda5 and sda7, and sda1 is not present, could I perhaps assume that you have deleted sda1, along with the first two Windows boot files - maybe?

[fincher1]

I deleted a partition, it was probably sda1 as you have stated haha.

[Quackers]

Do you have a Windows Vista/7 repair/installation disc? You can repair Windows boot with that. You will also need to set a boot flag, which probably disappeared with sda1

[fincher1]

So using the windows 7 installation disc, I should be able to fix all of this?

[Quackers]

Yes, but first use gparted from within Ubuntu to set the boot flag on sda2
Right-click on the sda2 partition in gparted and select "manage flags" then in the next window check the box marked "boot".
You should then see the word boot appear to the extreme right of sda2 in gparted.
It may be necessary to click on the green tick in the toolbar to apply the change (can't remember).
Once the boot flag is set you can quit gparted and reboot using the Windows installation disc. Press the required keys to get to the repair console. You can try the "repair my computer" option and when it doesn't find Windows (probably) you can select the command prompt option.
At the command prompt I would first try
bootrec.exe /fixboot
Then reboot and see if Windows will then boot. If not, please report back what happened.

[fincher1]

Ok, Thank you so much! I will let you know how everything works out. :)

[Quackers]

Feedback would be good :-)

[fincher1]

Hello, I am back!

As you said, "repair my computer" could not find an operating system. I went into the command prompt and typed "bootrec.exe /fixboot" and the message I got was "Successful". I restarted my computer, but GRUB didn't give me an option to boot to windows 7. Where do I go from here?

[fincher1]

Hello, I'm back! Sorry for all the posts.

I figured out how to add Windows 7 to the grub menu by doing the following:

http://erickoo.wordpress.com/2009/06/14/how-to-add-vista-partition-to-grub-2-ubuntu-9-10-karmic-koala/

When I reboot, I see "Windows 7" on the menu, but when I select Windows 7 it gives me an error. It says something like "invalid signature"

[Quackers]

If you run sudo update-grub in a terminal, grub should pick up the Windows 7 loader. Try that. (Unless you've turned off os-prober).
