Here is the situation, I have a system that was upgraded so the motherboard was chnaged and when I went to boot to WinXP setup/installation the HD was listed as "[unknown]" and not NTFS. It was originally formatted to "FAT32" but then was converted to "NTFS". Could converting it from "FAT32" to "NTFS" without formating the HD have caused this problem? Weird thing is I can view the files but WinXP setup shows the HD as an "[unknown]" partition. Is there an app that can fix this so WinXP setup recongnizes the HD as "NTFS "and not "[Unknown]"? Formatting would be a last resort as there are files that are needed. I have "Ultimate BootCD" and "Hiren's BootCD v8.4" but couldn't find an app that can fix this issue.
