go to walmart and buy a wrt54g. best 40$ ever spent.
we got ours back when we first got DSL. that was 5 years before i got RR and weve had RR for about 3.
i personally wouldnt advise it. check the boot.ini file. right click my computer and select properties. click on the advanced tab. then hit the settings button. click edit and make sure your partitions are set right. it should look something like this.
[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect /NoExecute=OptIn
thats what mine looks like but you may have to change some values depending on the way your partitions are set up.
