Help, Windows 7 Stuck in safemode loop CLASSPNP.sys

[Christian Smith]

I went into msconfig on the work laptop and changed the boot to safe boot network, as soon as I went to boot up the laptop and get into safe mode, the laptop freezes at CLASSPNP.sys then I have to reboot.

I really need to get it to boot back into windows normally, but even selecting "Start windows normally" sends it to safe mode because I set it to boot there in msconfig.

What can I possibly do? I've tried running start up repair but says it cannot repair the issue.
Due to security, the laptop hard drive has been encrypted with truecrypt, and therefore when I put the OS DVD in to try and do something from the command prompt, there are no OS's listed as installed so cannot alter the bootmbr or any windows files.

Did you have the Windows installation on your HDD encrypted as well? Then you must be using the "TrueCrypt bootloader" which resolves the Windows encryption under a password each time you boot your PC.
If this custom bootloader is damaged, you may use the Rescue Disk: TrueCrypt - Free Open-Source Disk Encryption - Documentation - Rescue Disk

I believe when you changed your Windows bootloader to "safe boot network", it conflicted with your TrueCrypt bootloader
