I suggest getting windows running BEFORE linux, as windows tends to be really hogish with the master boot record and tends to wipe over grub (or lilo) whenever anything needs to be fixed.... not that its a big dilemma or anything as you will need to then reinstall your boot-loader (google for it and there are heaps of guides)
