A weighted average is a more accurate measurement of scores or investments that are of relative importance to each other. This is often the case with investment portfolios, grade scoring and other statistics. You can find out how to calculate weighted averages. 1. Sit down with your data, a piece of paper and a pencil.
To specify the boot sequence: 1  Start the computer and press ESC, F1, F2, F8 or F10 during the initial startup screen. 2  Choose to enter BIOS setup. 3  Use the arrow keys to select the BOOT tab.  To give a CD or DVD drive boot sequence priority over the hard drive, move it to the first position in the list.
When booting a boot device, such as a hard drive, the BIOS runs the program code contained in the MBR of the device (this program is called the 'boot code' of the MBR). Repartitioning your hard drive, formatting partitions, or restoring partitions from backup will NOT alter or restore the MBR boot code.
