The simplest way for Linux newbies is to use mtools:

  mformat A:
  mcopy file A:
  mdir A:

/dev/hda8 = /boot partition = (hd0,7) for GRUB, partition table does

Partition table does not agree either.

These two, /dev/hda6 and /dev/hda7, are your /boot and root partitions.
Not /dev/hda8 as in grub.conf.

Here /dev/hda8 is the swap partition, whereas previously it was
/dev/hda10, see fstab. Editing your partition table reordered the
partitions.

So, let's see:

  /dev/hda5 : NTFS
  /dev/hda9, 10, 11 : FAT32

  /dev/hda6 : ext3 => /boot partition (due to its small size)
  /dev/hda7 : ext3 => root partition
  /dev/hda8 : Linux swap

1.) You would need to edit /boot/grub/grub.conf and replace (hd0,7)
with (hd0,5) everywhere, so GRUB finds your /boot partition again.
(hd0,5) is /dev/hda6, your /boot partition

2.) You would need to edit /etc/fstab and make the swap partition be
/dev/hda8 instead of /dev/hda10. Take out or correct the entries for
your /mnt/windows partitions, as they are wrong, too.

3.) You would need to reinstall GRUB into your /boot partition.
You can do that within the rescue chroot: grub-install /dev/hda6

In case you edit the copies of these files with Windows XP, be sure to
use a text editor which can edit and save Unix-style files. Else you
would need to process them with dos2unix when you're back in Linux.

[...]

Alternatively, what I would try: boot your XP bootloader, choose
Linux, and at the GRUB command prompt (you mentioned your system
doesn't boot further), enter:

  root (hd0,5)
  kernel /vmlinuz-2.6.8-1.521 ro root=LABEL=/ rhgb quiet
  initrd /initrd-2.6.8-1.521.img
  boot

That should start your system normally, albeit fail to activate the
swap space. The first thing you would need to do is to fix things 1,
2, 3 as described above.
