Hi, always remember to save the output of grub-mkconfig to your /boot/grub/grub.cfg, that doesn't happen automatically. I suppose that is your problem since GRUB2 shows all entries it finds in its config file even if they are garbage e.g. the partition or loader doesn't exist.I have this alias in my .bashrc so I won't ever forget.
I recently stumbled across the GRUB ntldr command. (Or is it referred to as a module? I am not sure what the correct terminology is.)
Apparently one of the things it can be used for is as an alternative to chainloader to boot the NT >= 6.0 versions of Windows as in the example below.
Dear Fedoraforum's users!
Initially I had win7 on my laptop.
I have formatted one partition (sdb2) with no data on it from ntfs to ext4 to install Fedora17
After formatting and installing I cannot boot to win7 anymore.
When pick Win7 in menu I have: "Windows failed to start.
If you’re running on ubuntu and want to install Windows 7 without burning a disc,you can try following steps to install Windows 7 with the iso file.

Hello All,
I am trying to triple boot a system with Ubuntu 11.10, Windows 7, and CentOS 6.2. I am able to boot into each one using os_probe. What I am trying to do is chainload CentOS 6.2 so that I may update kernels and not have to boot into Ubuntu to run update-grub2.
I was looking at the configuration for Windows 7 and it seems it is using chainloader to boot the Windows boot loader.
I am trying to install another linux distro besides ubuntu. However, I want to retain my existing windows based loader. Currently, as per my knowledge, MsDos loads grub which then loads Ubuntu (with loop back trick).
Now, I have a new linux distro installed on /dev/sda8 (/boot for new distro) where as /root for that OS is installed on /dev/sda9.
I tried following steps
1.
I've installed Ubuntu (~EFI mode) in a ASUS Zenbook UX32VD, which has Windows 8 pre-installed. It had Security Boot disabled.
I have gone through many pains to boot through my windows 7 partition.
I had windows 7, then one fine day I installed Ubuntu and again formatted the partition where Ubuntu was installed only to find the my Windows does not boot(Probably corrupted MBR). I again installed Ubuntu later but the Grub could not detect windows.
So i manually added windows by editing the file 40_custom.
