Did "Ultra Fast" boot cause system not to post?

[socklosk]

Twice now I was doing something in the Bios (changing boot drives or selecting “Ultra Fast” boot) and when I rebooted my system would not Post. I tried everything, like removing the battery, but to no avail. I took my computer to a technician and he assured me that everything tested fine. The only way to fix it, it seems, was to keep resetting the computer til it finally posted and we set the Bios to their defaults.

Would setting the boot cycle to “Ultra Fast” cause all this?

Ultra fast will only boot from GPT drives. If your drive is MBR your pc will enter a boot loop until the bios will revert the setting.
You need to convert your system drive to GPT but unfortunatelly this cannot be done without losing the data. Restoring backups will not work either so an OS reinstall is needed...

I have GPT on my boot SSD.

Ultra fast skips a lot of checks so:
1. Make sure you have the latest bios - initial versions are always flawed in one way or another
2. Recheck your bios settings (memory, oc, graphics) it might be that during fast or normal boot the bios detects the wrong setting and reverts it but ultra fast doesn't.

Now the Ultra Fast mode is working fine, although I did switch to Corsair Vengeance from my new backup computer. If the other computer flakes out with the same symptoms, it's probably the RAM.
