Hi!
I short summery of my problem first: I have a Lenovo Thinkpad and installed a new Windows 8 on an Ultrabay HDD, while having my regular, PGP WDE encrypted harddisk still in the notebook. Thereby the MBR of my regular harddisk got overwritten by the Windows 8 bootloader, preventing the PGP startup screen to apear. So I was no longer able to boot into my regular (encrypted) Windows XP.
After that, I used the recovery disk to decrypt the whole disk (that took about 30h, but finished without failures).
But after decryption I still was not able to boot (got a "no operating system found" error). I tried connecting my harddisk with two different PCs (Linux & Windows 7) and both did not recognize the disk / file system. The recovery CD does not find any PGPWDE installation on the disk anymore, so the disk really seems to be encrypted.
I used testdisk on my Windows machine to recover the lost filesystem, but I does not find anything (by now I only used the Quick Search).
I have no idea what to do at this point. I have some really important data on this disk and I don't know what is the problem right now. The disk should be fully decrypted and I should be able to recover the data somehow, I think. Any suggestions?
