Hey,i've just built my first PC and when it boots into BIOS it says no "Boot device detected" or something like that,I've plugged a sata cable into the hdd and one end into the Sata header on the motherboard.Have i connected it wrong?

 
For USB install on most motherboards you cant just select USB as first boot device.
Insert USB and power on pc and enter bios, then go to Hard Disk Group (might be labeled something slightly different). Then from that list select your usb drive as first hard disk, then make sure hard disk group is the first "boot device" in the boot list.
 
on hard drives and other sata devices there two plugs per device. one is the data cable the other is power. also check that your plugeed into the sata port 0 on the mb. some mb have two sata chipsets and the second set may not boot hard drives.
 
No boot device detected does not mean that it does not detect your hard drive, it means no drive has bootable data in it. You have to install windows first.
You will have to install windows or other operating system with a cd or usb drive.

You should be able to enter bios setup and see your list of hard drives, now if it does not list your hard drive in your device list then there is an actual issue.

I got it working-ish,it wasn't plugged into the power supply :D But now instead of going into bios it says "reboot and select proper boot device or insert boot media in selected boot device and press a key" I'm gonna install windows off of a usb btw
