can't create a file on the ntfs partition

Hi;

I booted my WinXP laptop the other day and got an error message "...hal.dll is corrupt or missing....". Now I can't boot into windows. I figure I can boot from the Knoppix CD (v3.6) download the hal.dll file and copy it into the system32 folder. (Using Knoppix for the first time)

However, after I have mounted the ntfs partition via Knoppix and try and create a test file I get a message saying "...operation not supported.." I have also tried creating a test file via the GUI but get a message saying that it can't create the file. This is what I have done:

To make the ntfs partition writable:
vi /etc/fstab (changed /dev/hda...... from ro to rw)

mount the drive to be rw:
mount -o remount,rw /dev/hda1

To create a test file in /mnt/hda1
touch testfile

The exact error message:
touch: cannot touch 'testfile': Operation not supported

Any ideas?

thanks.

How about booting with the XP cd, going to recovery console and doing:
BootCfg /Rebuild
Fixboot

If you've changed C:\boot.ini that might be the reason and you could try:
boot from disk (win)
attrib -rsh boot.ini
ren boot.ini boot.bak
reboot
