cannot dual boot w7 & fedora 12 grub config

[Tessa]

Hello Everyone,

Goodness , I thought I'd try a w7 dual boot with Fedora 12 so I can try to learn Linux. I am a "total" n00b !!!

Can someone please, please tell me what to do or help me configure grub.conf so I can boot back into w7? I'm not even sure if Windows 7 is still there, i think it is. I am in hopes I won't have to re-install everything.

The error I get when I try to boot into W7 is: Error 13: invalid or unsupported executable format.

I have one 160 GB HD with W7 installed, shrunk the drive, installed Fedora 12 on the un-allocated partition, and attempted to edit grub.config to have the option to boot into either OS.

I get Error 13: invalid or unsupported executable format when I try to boot in w7.

This is the info I have but I don't understand any of it.

Hi!

Still cannot dual boot to w7 with above modified grub.conf. Error 13: invalid or unsupported executable format.

current grub.config is as follows:
default=0
timeout=12
splashimage=(hd0,1)/grub/splash.xpm.gz
#hiddenmenu
title Fedora (2.6.31.5-127.fc12.i686)

Mount Windows partition in Fedora and check its contents.

su -
mkdir /media/windows
mount -t ntfs-3g /dev/sda1 /media/windows -o defaults,umask=0
cd /media/windows
ls

Does mount command work fine? Does ls command list contents of Windows OS partition.
