Can't boot into Win7 since Update to 12.04

Solution 1:

How to use boot-repair to provide a "Bootinfo Summary"

If you can boot Ubuntu, you can install and run the Boot-Repair tool and use it to create a BootInfo summary.

First, install the tool using apt-get. The terminal commands to do this are

sudo add-apt-repository ppa:yannubuntu/boot-repair
sudo apt-get update
sudo apt-get install -y boot-repair

After that completes, enter the command boot-repair to start the tool.
After a slight delay, boot-repair will prompt you to download the newest version. Since you just installed the latest version, answer No.
If boot-repair asks to install the pastebinit package, respond with Yes.
The tool will now scan your system and (eventually) display the window shown in the image below. Click on the Create a Bootinfo summary box/button. This will collect information about your system's boot configuration, but will not make any changes.
When the bootinfo summary has been created, boot-repair will display a message containing a URL which should look like this: http://paste.ubuntu.com/123456/.

Please update/edit your question and add this URL. The information in the pastebin this link points to will help us diagnose the problem.

Solved:

I reinstalled Windows (all I had was an install disk, it wouldn't let me "repair" from the menu....something about partitions not showing up how they should have been....)

anyways .... I did a custom/clean install of Windows7, when it was all finished, I again had my option of "Ubuntu or Windows 7" as if nothing had happened at all.

Sure enough, I loaded into Ubuntu 12.04 like nothing had ever happened.

=====================================================

Not sure why that all happened, but I only lost Win7 information (not important cause it's only used for Netflix, LOL

Now hopefully this post helps someone else someday.

Thanks!

Solution 3:

Assuming that your primary disk is sda, try:

sudo grub-install /dev/sda
sudo update-grub2

With this you can enter on Windows, and if you want install EasyBCD after.

Solution 4:

Boot into a Windows recovery CD (ask your computer manufacturer for one) and open a command prompt. Then type this:

bootrec /fixmbr

Next you will see the Windows Bootloader instead of GRUB. Now follow the steps here to get GRUB back:

IGNORE the Restore MBR Step!
