I'm going to go with grunt... I really would recommend you get a second HD spyder - doesn't need to be huge at this stage. It isn't more strenuous installing linux on the second HD you just have to be careful and make sure which drive you're putting the linux partitions on (should be on /dev/hdb rather than /dev/hda). install lilo (or whatever you use) to the boot sector on hda i.e. your first drive... or alternatively install it to floppy disc (that way if you do ***** the boot manager up, its a bit its easier to get back into windows to get on the net find out what you did wrong and correct it)
