So I have a HDD partitioned with 4 fully encrypted volumes (3 TC, 1 VC in TC Mode). After Windows died on me and I tried to rewrite EFI BCD, it seems I accidently may have done so for my TC HDD, when I open WinHex it tells me the drive is formatted as EFI. When I want to mount it now, it only shows me 1 partition instead of 4 and tells me invalid password. My last backup is 3 months old and I desperately need the files. Please, please help! Edit: I have followed the Guide by @dantz and created a block with Winhex, which I was able to mount using TC with 1 of the passwords, where to go from here?
