Please use your Registry Editor to check if this Key is present:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SafeBoot
If it isn't then it is possible that it was removed by some form of virus/malware, your machine maybe clean now, but cleaning won't put the Key back.
See for explanation: The Undeletable SafeBoot Key « Didier Stevens then check #'s 16, 17, 18 in Comments.
If it is, it may be related to your having your OS on the SSD, and or in how the Raid is set-up.
I wouldn't be able to help with that because I do not have experience with SSD's or Raid's.
