nervous dual-boot query

My friend wants to try Linux so I said he could use my SUSE 8.2pro disks to try an install alongside his current XP pro. I gather from here and elsewhere that this is OK with SUSE. Perhaps he will like it and we can share the cost of SUSE9 (both a bit strapped for cash). I'm slightly nervous about "helping" him, as I'm not exactly an expert. Also my own install is SUSE only so I'm not sure about the dual-boot thing. His filesystem is NTFS, no partitions. I figure he should use partition magic to make a Linux partition before we start with SUSE. Is this correct? And grub is the way to go re dual-booting presumably? I ask because he was going on about some windows boot-loader. Oh no I remember, it was boot-magic. Jake
