Installing windows xp on a seperate HD
 

how would i go about installing winxp on my 160 gb drive and have lilo pick it up so i can boot into it .. i already have Mandrake 10.1 installed on an 80 gb ..

can some one give me instructions ?

In order to get XP to work you need to install it first. Once you install that then install your linux and let it's boot manager deal with XP, which it will play nice with. XP doesn't play nice if it's not the first installed.
