So everything is bad because my MB(ASUS M5A97) suddenly cannot discover gpt partitions? I have not said it in first mail but this boot situation started after I tried to resize one partition in Acronis Disk Director 12 and it failed. Maybe it did something to gpt tables. But archlinux can work with them so it's strange.

Well, you firmware sees two partitions - (hd2,msdos2) and what is
probably protective MBR on hd1. It does *NOT* show any trace of GPT
partitions on hd1.

Could you please boot EFI Shell and attach output of "map -v" command?
