I have a dual-boot system with Win 7 and XP-pro (on a second HDD). There are two other partitions which I use between both OS's and have Win 7 designations D: for data and E: for setups/backups. Win 7 has the usual primary,hidden,system,boot partition named WinRE and in windows 7 it is not seen and not assigned a drive letter. So far, so normal. However, when I boot into XP-pro on the second drive, then unfortunately the WinRe partition is seen, and being the first partition on the 1st HDD, gets assigned drive letter D: That letter cannot be changed, so I can't actually have the same two partitions as D: and E: in both OS's apparently. Or is there a way to make the WinRe partition invisible to XP-pro (currently unchangeable assignment D: ?
