There is probably a long way to recovery, rebuilding system from backup might be faster.
You can try WinTech CD to see if anything is still visible, but I would not bet on it.
Which version of SafeBoot do you have installed?
First - what is this "safeboot" you speak of? You mean the 1999 product SafeBoot 3.5? I'm hoping you mean one of the later products from the 'company' SafeBoot, like Drive Encryption for PCs or the McAfee product Endpoint Encryption for PCs? Got a version number?
In some versions, like 5.x+ changing the partition size is fine, moving safeboot.x files in the root of the boot drive, not fine. In earlier versions, it's not really fine ever.
What's the error message you are getting? OS not loading could mean anything..
The version of SafeBoot [the product] we have here is 4.2 (yes, a bit old). Meanwhile the IT guy succeeded in running SafeTech and, after disabling virus-protection of the MBR (probably SafeBoot sees the change DiskDirector did as a virus attack), it was possible to decrypt the drive.
However, right now it appears as though there's no file system and partitions at all... All the data is intact I would like to believe, yet it is raw. Of course it is not possible to load the OS. Is there some way to restore/recover the partitions and the file system?
If the drive is indeed decrypted (did you check the workspace etc to see what the sectors look like), then there's no "SafeBoot" anymore - you can use all the normal partition recovery tools that engineers use to fix it.
