[SOLVED] motherboard doesn't boot

[BenignPage05]

So I recently got a gigabyte z68 motherboard and I'm having a lot of trouble with it, first of all, it is refusing to detect my hard drive, it's telling me to set the HDD to UEFI mode, but I can't seem to do that from the bios, which is legacy. it's telling me the exact same thing when I try to plug in a windows flash drive.
if anyone has any suggestions I'm happy to hear them!

some motherboards needs their bios to be updated, did you buy it online or from offline store?

2. Select the appropriate drive (list disk and select disk n) and remove all partitions (clean)
3. Create the UEFI boot partition: ...
4. Create the Windows partition:
