I installed Yosemite yesterday and it was working fine.
Now whenever it tries to boot it runs Safe Mode and fails 1/3 of the way through.
From what I can remember I went to enable FileVault and backed out of it as I didn't enter my correct iCloud information, and didn't want to go down the key generation route.
I also tried to enable TRIM.
This morning I restarted my machine after installing Kies and it wouldn't boot. The error I'm getting is this:

What could be causing this error?
I've tried two things:
- Installing mavericks from the recovery drive – this fails.
- Disabling trim from the command line.
Neither of these work, is there something else causing this issue?
Edit: verbose mode stops at "still waiting for root device"
Best Answer
Yosemite apparently uses a new security feature called kext signing. This will prevent the old method of TRIM enabling. See the Trim Enabler FAQ, The question Recovering from stop sign on boot screen might help you:
Please check the original source for updates!
EDIT:
See my answer here: Since the release of 10.10.4, Apple now provides a new tool called
trimforce
, allowing users to activate TRIM also on unsupported disks. No more dangerous experiments with third party software necessary. /EDIT
