I want to be able to boot my X230 in UEFI only (CSM off). Lenovo media for X230 does not seem to be UEFI bootable, so I boot it with CSM on. The Recovery program asks about the GPT or MBR partitioning with the explanation that with GPT it will be bootable in UEFI only. But when I reboot after recovery and turn CSM off, the "Starting Windows" screen freezes endlessly. There is some hdd activity, but no Windows are loaded.
Any clue what went wrong and how to fix it? Thanks.

You need to enable CSM when ever booting to external devices, so that is normal.
The difference between GPT and MBR is that the newer GPT is more robust, secure and allows more partitions and better error recovery, but both should work.
If you press and hold down the [F8] key, and then turn on the comptuter, do you get the option to boot in to Safe Mode, and if so can you boot in to Safe Mode, or Safe Mode with Networking?
I presume that you are recoverying due to a prior problem, so more informaiton on why you were recovering may be helpful.
Best of luck

I can boot in Safe Mode but it stops right after disk driver or so. I can check what's the last thing that gets loaded.
I am recovering because I replaced orginal HDD with a brand new SSD (Fujitsu FSX-240GB). I wanted to start fresh (and get rid of legacy bios as well).

Yes, the 64-bit version of Windows 7 is UEFI compatible and can be installed on EUFI complaint hardware.
