New to Hackintosh world, installed Yosemite on an HP Folio 9470m laptop (4GbRAM, 320GB SATA HDD,i5) with a supported Atheros wifi card. All works fine if I boot from usb stick but trying to boot from hdd the laptop reports no OS found. It doesn't look like it can find the boot loader. I'm proficient in Linux & Windows, some experience of BSD Unix but so far, after probably 20 installs, several hdds and even a different laptop I'm no nearer getting the system booted from the hdd directly. The hdd has been erased before each install, using both HFS+ Journaled and with Case-sensitive option, the same results from each flesystem type.
Bios boot mode is Legacy - trying either of the UEFI boot modes results in no EFI file being found.
Some advice would be welcome please
