[-- Attachment #1 --] I recently reinstalled Windows XP on my laptop (I barely use it but occasionally it comes in handy :) and when I did the install it made the base drive E (no idea why, and I couldn't see how to change it). Everything proceeds as usual and then I boot a CD to then jump start my system and run boot0cfg to re-write the boot loader. Alas the next time I boot Windows it logs me out straight after logging in. I do some googling and find that it is most likely that the signature bytes Windows uses to determine which drive is what have changed and it has now made the drive C:. Hence the swapfile location is now incorrect :( I was wondering if it would be possible to modify boot0cfg (and boot0 I guess) so that it avoids touching these bytes. I found some details here -> http://www.goodells.net/multiboot/partsigs.htm Basically it would appear to be the 4 bytes just before the partition table. I'm not sure how big boot0 is though :) -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (FreeBSD) iD8DBQBGXkqB5ZPcIHs/zowRAgs3AKCDO0dU6nIaJ0cABv1bea+tSQ44CwCePmaG rCyFyZipLsjPhhwfAJ/Ts/k= =KUvL -----END PGP SIGNATURE-----
