The stars are all in line, and hell is icy! Your suggestion worked! Here's the story, in more detail, for the archives. I rewrote the relevant stanza of /boot/grub/menu.lst to read # This entry automatically added by the Debian installer for a non-linux OS # on /dev/hdb1, "map" lines added by hand. title Windows XP map (hd0) (hd1) map (hd1) (hd0) root (hd1,0) savedefault chainloader +1 I then rebooted into Windows XP. It went _directly_ to "Windows XP Professional Setup," without asking permission (of course), deleted a slew of files and copied a bunch more to hard disk. While this was going on, I was thinking, Let it do what it wants, since it's really on hdb, thinking its on C:. When it was done, it rebooted into grub! And my sid installation is still there! Hurrah! So I booted back into Windows, and this time was in the regular Windows XP Pro Setup, which claimed "Installing Windows" supposedly "to complete in 39 minutes." It took less than 15. Rebooted again, and found I had choices: back to the installer, or two identical lines reading "Microsoft Windows XP Professional." The first one produces a brand new installation of XP, complete with request to register it with Micro$oft. But the second line provides my whole old installation, even IBM Client Security! Half an hour of checking suggests everything still works. Whew! Is this a great list, or what?! And particularly, thanks Dave! -- JohnRChamplin@columbus.rr.com ==================================================== PGP key 1024D/99421A63 2005-01-05 EE51 79E9 F244 D734 A012 1CEC 7813 9FE9 9942 1A63 gpg --keyserver subkeys.pgp.net --recv-keys 99421A63
