Jim, I'm running Win 98se on C: and Windows 2000 on D:. fdisk /mbr will not effect other aspects of windows 3.x or 9.x; NT needs a bit of care on other logical disks. If you're running NT, let me know, because the fix is a bit complicated. More than a bit, but doable. Linux would be easy to fix afterwards if the microsoft tendency to overlook other unix-like partitions rears it's ugly head. Just be aware of the latter, you'll be all right; i.e. backup critical sections, etc. regards, Jim Griffin PCBUILD maintains hundreds of useful files for download visit our download web page at: http://nospin.com/pc/files.html
