You can re-edit /etc/fstab by booting the live DVD and mount your drive. Here is an example on how to do this.
Boot from the live DVD and open a terminal as root. First use fdisk -l to identify your partitions.
This example is from a system that uses default partitioning of Fedora 19.
[root@localhost ~]# fdisk -l
Disk /dev/mapper/live-rw: 8589 MB, 8589934592 bytes, 16777216 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk /dev/mapper/live-osimg-min: 8589 MB, 8589934592 bytes, 16777216 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk /dev/sda: 21.5 GB, 21474836480 bytes, 41943040 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk label type: dos
Disk identifier: 0x0003948c
Device Boot Start End Blocks Id System

/dev/sda2 1026048 41943039 20458496 8e Linux LVM
Disk /dev/mapper/fedora-swap: 2164 MB, 2164260864 bytes, 4227072 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk /dev/mapper/fedora-root: 18.8 GB, 18782093312 bytes, 36683776 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Mount the root partition.
mkdir /mnt/root
mount /dev/mapper/fedora-root /mnt/root
Edit /etc/fstab with vi.
vi /mnt/root/etc/fstab
Reboot and you should be good to go.
/sbin/shutdown -r now
If you need to restore Grub then please see my answer for question 34772 (this is a link) on how to restore Grub with a default Fedora 19 installation.
You could reinstall grub by using either a Fedora 19 DVD or a netinstall image.
When the CD/DVD boots, choose Troubleshooting ---> Rescue a Fedora Installation from the menus presented.
Once the system boots, the installation image should automatically mount your installation under /mnt/sysimage. Once that happens, all you have to do (hopefully) is
chroot /mnt/sysimage grub2-mkconfig -o /boot/grub2/grub.cfg grub2-install /dev/sda
This will install GRUB to master boot record. Also, ideally, when you run the first command, in the output, you should also see Windows 7 presented.
Hope this helps.
You should probably inspect your /etc/fstab while you are in the chroot; changing /etc/fstab does not affect your GRUB configuration. Compare to blkid output to check UUIDs.
