I went to a lot of trouble to consolidate the 100 mb (BCD/bitlocker etc) partition that Windows 7 unexpectedly created when I installed 7 some months ago.
Since then I've configured a 7/XP as multi-boot system and thought it was stable. C: stored 7, D: stored XP, and there were 2 additional partitions.
Tonight Partition Wizard (bootable) tells me there is an unallocated 7.84 mb logical partition occupying sectors 0-16064. Neither 7 nor XP reports the existence of this space.
Definite details about the origin of such a storage mystery would be much appreciated.
