I made a setup with triple boot last week and it works fine, two xp and one linux, and grub as boot loader, I made a script in menu.lst configuration for grub where I hide the xp installations from one another: title XP1 unhide (hd0,0) hide (hd0,2) rootnoverify (hd0,0) chainloader +1 makeactive title XP2 vice versa... But I noticed a quite strange thing, when I change user password in one of the xp installations, it also changes in the other, how come? I also installed a mouse in one installation, and when I booted the other, it said that it was installed, I've checked with partition programs, and the other xp is marked as hidden in both, I don't get this, do you? My partition table is as follows: NTFS 12.7 GB Primary NTFS 5.3 GB Primary Linux Ext3 3 GB Primary NTFS 17 GB Logical If you have some idea, please let me know Title edited -- Please, use [TAGS] in your topic's title.
