How to escape a Deep Freeze boot loop on Windows by switching from Frozen to Thawed mode using a recovery OS to replace the Deep Freeze state file.
To remove frozen mode without access to your windows, you must use a recovery OS. You can use either Any Linux LiveCD, HBCD, Windows Recovery CD, PXE Solution or whatever to load any NTFS/FAT Supported OS.

3. or Use the recovery console on your Windows CD (not recommended - using command line)
Solution
Load your system from recovery CD or LINUX or any Live environment. the file which controls the DF (Deep Freeze) State located on C:\. if you have version 5, or version 6.
DF 5 : Replace file : Persi 0.sys
DF 6 : Replace file : $Persi0.sys
you need to repalce the file in drive C with the same file.
Just browse using any file-explorer to drive c:\, copy the file to other location, and then - copy it back to the same place.
if you need help to copy the file itself from command:
from Command:
mkdir c:\\temp copy c:/Persi o.sys c:/temp copy c:/temp/Persi o.sys c:/
Restart.
