HTC one only boots into recovery I installed kitkat 4.4.2, via clockwork mod and the install went smooth, no issues. 

I rebooted, and now all I can is my bootloader and recovery, whenever I try to normal boot.  It simply takes me to recovery. 

The bootloader states my phone is 

*** TAMPERED ***
*** UNLOCKED ***


Which seems fine, it was the same with a previous rom I've used. 

I tried a few things, clearing cache, factory resetting the phone etc, no change.

Any ideas where I'm going wrong?
You need to re-flash your recovery in fastboot. Make sure you use the correct recovery for your device and carrier. (I can provide links if needed.) Your rooted so I will assume you have successfully achieved S-Off which requires proper adb drivers and fastboot.


boot to fastboot (hold power + vol down) and connect USB cable
flash nameofrecovery.img (from same directory adb and fastboot are in) by typing


fastboot flash recovery nameofrecovery.img
