Gigabyte GA-Z97-HD3 boot issues

[elliot_]

Hey guys, this is my first time posting here so please correct me if I do something wrong. I just built my first pc, mobo is a Gigabyte GA-Z97-HD3, cpu is i5 4690k, and I have 8 gb of crucial ballistix xt ram. Whenever I start up my pc (note: os not installed yet) I just spam delete or f12 and it still does not let me into the BIOS. Instead, it shows a message saying "Missing Operating System". I would love it if you guys could help me.

EDIT: Yes, I have tried installing windows before and everything went fine until it told me that it had errors making a partition, I think error no. 0x80070057, maybe that's the issue? It later showed me that I had a 350mb partition or something

try with an older keyboard as some keyboard have compatibility issues and the bios doesnt recognize them, thats why if you look at the k70 keyboard it has a bios switch and that lets you get into bios if you cant.
