I have a windows 2k server that I am rebuilding. There are two identical IDE disks that I want to use for mirroring. During setup I partitioned one to have two partitions, and left the other unformatted/unallocated. I understand that I need to upgrade the disks to be dynamic for mirroring, however when I choose to upgrade in storage management, the unallocated disk upgrades no problem, but the boot/system disk warns that I will be unable to boot previous versions of windows after upgrading. If this is the case, how am I to upgrade the boot/system volume to dynamic If I am unable to boot the OS afterwards?
