Dear rony, Apart from normal sectors of harddisk MBR is Very less written sector of the Disk, Imagine the number of time the normal data sectors get written and overwritten when U copy, move or delete data I don't think it ( MBR ) will get damaged or so... If U have experienced such a thing in past it might be that the harddisk is faulty and not be due to too many flavors of OS installed So go ahead install as many flavours as U like and Ur Hard Disk space support !! Tell me more Like To hear from U Rony Wrote ============================================ Too many linux flavours cannot be installed together in one HDD and constant loading, reloading, formatting may damage its MBR or other sectors. ============================================ Regards, Shailesh ===== Technology is driving Me CRAZIER ....
