"...there may be another BIOS settings that lets you order the hard drives."
ou talvez theadler em link descreveu um pouco melhor.
In your bios, under the boot menu, is there a a tab or link for Hard Drive BBS Priorities? If there is, in it change the first drive to your SSD, if it is in the drop down list. Then go back to the boot menu and the drive should show up under boot priorities. I don't know if your bios has this option, but mine does and I had a similar problem right after installing windows.
