Resolution:

  1. Boot from a Linux Live CD (with NTFS write ability if neccessary)
  2. Mount your Vista partition (you may need to run ntfsfix in order to mount the partition)
  3. From the terminal, navigate to the partition where Windows Vista is installed.
  4. Type cd \$Extend to navigate to the hidden folder $Extend. Note the backslash, which is neccessary to escape the $.
  5. Type cd \$RmMetadata to navigate to the hidden folder $RmMetadata.
  6. Type rm -rf \$TxfLog. This will recursively remove the $TxfLog folder
  7. Restart your PC.

    You may be lucky at this point and your system will boot straight into Windows, otherwise you will need to boot from a Vista disc to access the Startup Repair functionality. If you do not have a Vista DVD, you can download a bootable recovery image from the NeoSmart Files

    To use the startup repair functionality:

  8. Boot from the Vista DVD, and select "Repair my computer".
  9. Select your Vista installation, and click next. If it does not detect any installations, click next anyway.
  10. In the system recovery options, choose startup repair. When it asks you to reboot, do so.
  11. Remove the Vista DVD to allow your system to boot normally, and if asked "boot normally".
