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.
There may be anywhere from 0-3 items to change in the BIOS to make this possible assuming your BIOS supports it. Some older bios's may refer to your flash drive as a USB floppy or USB zip. 2. The USB flash drive must support booting from it in general. 3. The flash drive must contain the boot/system files. 4. The flash drive must have bootsector area. This is done with special utilities.
