no active partitions but Win 7 boots

[forepaughs]

Win 7 64 bit, Single SSD, 3 Healthy partitions: 100MB EFI System / Boot, Page File, Crash Dump, Primary / My Data Primary. Disc Manager shows no active partition, yet Win 7 functions perfectly.

Is the EFI System partition "active" by default even though it does not list as such? It's the only answer I can concoct.

Thanx to all who respond.

Yes, in Windows 7 the 100MB SRP is the active partition.
