Ensure the SSD drive is the first hard disk to boot
As you can see from the screenshot of the Award Bios setup screen on my Gigabyte motherboard, there are a couple of options which let me order the hard disks so that the SSDNow drive boots first.
Solid atate disks (SSD) offer an easy, and relatively inexpensive means of boosting the performance of an older PC. The SSD behaves like a standard hard disk, but it uses memory chips instead of hard disc platters, so it is significantly faster, quieter and more reliable.. In Windows, if the operating system and paged memory are migrated onto the SSD, the PC's performance should increase significantly. It is possible to run several operating systems, like Ubuntu and Windsows 7 using separate partitions on the SSD. You will then use a boot manager, like the one that installs in Windows, to select which operating system launches.
