Primary boot sector is invalid


Hi,
I have upgraded from Debian Sarge to Etch.
Until now I cannot boot windows form my first partition with grub.
error:
Code:
Filesystem type unknown partition type 0x7
Furthermore I get this messages while I'm booting Debian:
Code:
NTFS driver 2.1.25 [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 warning (device hda1): read_ntfs_boot_sector(): Hot-fix: Recovery of primary boot sector failed: Read-only mount.
NTFS-fs warning (device hda1): read_ntfs_boot_sector(): Using backup boot sector.
NTFS volume version 3.1.
Here is my win-related part of my /boot/grub/menu.lst:
Code:
# This entry automatically added by the Debian installer for a non-linux OS
# on /dev/hda1
title           win
root            (hd0,0)
savedefault
makeactive
chainloader     +1
And finally my fdisk -l:
Code:
Disk /dev/hda: 250.0 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

/dev/hda10          30316       30401      690763+  82  Linux swap / Solaris
What can I do?

The grub-entry for windows should say:
rootnoverify (hd0,0)
instead of:
root (hd0,0)

Yes, I tried. But there was the same problem and "root (hd0,0)" had always worked before.

I have done a fixboot with my win-setup-cd to delete grub form the mbr. Now I'd succesfully booted win with a previously created lilo-floppy.

edit:
now back to linux (with lilo) there aren't ntfs warnings/errors any more
