I just bought Windows 8, which I downloaded to my PC. The PC has full drive encryption, and I selected "Keep nothing" type of install for Windows 8.

When the downloader finished and restarted the computer, I was again prompted for by TrueCrypt password (which is accepted) and a few seconds later, saw the "Something went wrong" message in the installer.

The computer rebooted, and now it claims my TrueCrypt password is wrong. Wtf do I do now?

PS. I backed up everything and don't have a TrueCrypt rescue disk.

Windows 8 has several new features incompatible with Truecrypt - the feature called Secure Boot, mainly; and possibly Windows 8's new hybrid boot. Therefore, full system drive encryption is not supported by Truecrypt (http://www.truecrypt.org/docs/sys-encryption-supported-os).

With Windows 8 Secure Boot enabled (by default on supported hardware) Truecrypt will never work (the point of Secure Boot is to prevent bootloader modification or "hijacking"). Check if you have Secure Boot enable first (http://www.eightforums.com/tutorials/20208-secure-boot-confirm-enabled-disabled-windows-8-a.html).

I would consider using Windows 8 Bitlocker encryption in place of Truecrypt at this time as using Truecrypt with Windows 8 should be considered unstable and a "hack" at best.

Assuming you can access your computer's BIOS menu, and you have a Windows ISO (XP, Vista, Seven, or 8), I would advise the following:

  1. Boot from your Windows CD.
  2. Choose "Advanced options", then "Recovey console"
  3. Run fixmbr

This should overwrite TrueCrypt's bootloader, and make it possible to resume the setup. It is also possible that something went wrong with the setup, in which case you will have to start over, using the Windows 8 ISO.
