grub/NTFS/MBR death

Not sure whether this should be in hardware/software forums, but here it goes... I'm running Fedora Core 5

Alright, having my MBR completely mowed over numberous times and after many HD switches, I had a large, NTFS partition as my boot/OS hard drive. My linux partition is on another drive. I had grub-install install itself onto my MBR; a mistake, onto my NTFS drive. I have (had) windows XP on that partition. Of course, I cannot boot into it... having the grub bootloader boot into (hd0,0) boots itself back into the grub loader... I think I just made a 40GB MBR

Anyway, windows recovery console can't find it, and I tried fixmbr from the line to no avail. So, fdisk still shows my disk as being NTFS, howeaver, trying to mount it won't work... apparently 'ntfs' isn't a recognized FS. I have another NTFS, which is withen an extended partition, and I can't mount that either...

Anyway, point is; Would there be any way to at least ACCESS my drive, just to back data up off it? I have several other fat32 partitions on other disks that can be written to from FC5, so if I could just access the partition...

Any help would be GREAT!

Thank you!

dmesg | tail returns...

NTFS driver 2.1.27 [Flags: R/W MODULE].
NTFS-fs warning (device hda1): is_boot_sector_ntfs(): Invalid boot sector checksum.
NTFS-fs error (device hda1): read_ntfs_boot_sector(): Primary boot sector is invalid.
NTFS-fs error (device hda1): read_ntfs_boot_sector(): Mount option errors=recover not used. Aborting without trying to recover.
NTFS-fs error (device hda1): ntfs_fill_super(): Not an NTFS volume.

Anyone know any programs that can attempt to recover a messy boot sector/partition?

Or am I going to have to contact the NSA for help...

Does that mean you got things to work again ???.
Sounds like you installed grub to the NTFS partition (boot sector). As well as the MBR I mean.
If you got out of that with fixmbr/fixboot you were very lucky.

Note: - installing to the MBR is safe. It is installing to /dev/hda1 (i.e. the partition) that eats things.

Hope all is o.k.
... and about those backups ...
