OCz Vertex 2 probably has an eraseblock size of 512kiB, so 1MB alignment works Pregap only needs 32 sectors; boot only needs about 16MB Make sure luks partition (type 0x44) is aligned to 2048 sectors (1MB) on both sides! Leave about 40MB at the end.

uEFI won't boot from that. Since mkdosfs was giving warnings, try with a larger EFI part?
