Yes, board is downright ancient, and CPU is Core2Duo. Nevertheless, a couple years ago I managed to install Mavericks on it. Then I completely forgot how I did that.
Now, a week ago I bought SSD and decided to move to Yosemite. I actually managed to install it (booting Clover from HDD, it seems) and move everything from the old HDD. Then I formatted HDD. That was very bad idea. I couldn't boot anymore, got "no bootable drive".

It turns out, board is legacy, but it seems to have some UEFI functionality. For example, I can boot from legacy, MBR flash (made by Unibeast, of all things), and then I get to Boot Maintenance Manager, which offers me to boot EFI files.
I narrowed my problem to PBR — I can boot from legacy MBR flash, when it uses boot0af → boot1 → boot5 loader chain. Problem is, if I install Clover on system drive, it boots boot0af → boot1 → boot6 chain, which doesn't work. And I can't google anything about boot5 loader — Clover wiki says that boot6 is default x64 clover loader, but there's nothing about boot5. I can install Clover with additional PBR option, and press 5 when booting, and it works, but I don't know how to make it default.
Anyone ever dealt with this stuff?
