When you start a Windows Vista-based computer, you may receive the following Stop error message on a blue screen:
This issue can occur if the system file $TxfLog file has become corrupted. The Common Log File System (Clfs.sys) driver does not fix the $TxfLog file when the file becomes corrupted. In addition to the Stop error message, Windows Vista may not start until the offending disk is removed or repaired.
To resolve this issue the corrupted file needs to be repaired. This can be accomplished by booting to an installation disk that has the ability to self heal this type of issue. This can be done with a Windows 7 Beta installation disk. To recover a Windows Vista volume with Stop Error 0x0000C1F5 without data loss, perform the following steps:
1. Obtain a Windows 7 Beta or later Windows 7 installation disk
2. Insert the disk into the disk drive and boot from this Windows 7 Beta installation disk
Note: Once booted, cancel out the Windows7 setup. Do not install Windows 7.
3. Once the system has booted successfully, remove the Windows 7 Beta installation disk and reboot the computer from the hard drive.
Note: The Windows 7 Beta installation disk includes self-healing code that resets the corrupted $TxF RM log file, therefore the problematic volume should be recovered by simply booting from the Windows 7 Beta installation disk.
