Replaced Motherboard won't boot from SSD
My MSI GD65-Z77A motherboard failed about 2 weeks ago so I RMA'd it and my new one just arrived yesterday. I hooked everything up and it is working properly, except when I boot up it goes to my HDD which still has an old copy of windows 7 on it. I made sure the SSD was plugged into the first Sata port because I read somewhere that helps, and I also made sure the SSD is the first device to boot in the bios. If I boot without the HDD plugged in everything works as it should and I can just plug it in after windows has started, but that requires me to take the side panel off my computer and it's just a big hassle. I also attempted to delete Windows off the old hard drive, but it said I don't have permission, so I gave myself permission under security in properties and it still says I need permission from myself. I've completely run out of ideas and have not been able to find any currently existing threads that fix my problem.
