Enter setup boot menu

This can depend on your OS. For slower booting systems, press and release F12 repeatedly after pressing the power button. Release the button when you see the Choose Boot Device screen. Select the boot device and press Enter. (Note: some systems may not boot from all USB devices or CD/DVDs if they are set for a type of secure boot (UEFI).)

With some systems, you may need to enter the BIOS setup utility to allow the system to boot from a specific device. Try pressing F1 repeatedly after pressing the power button until you hear a lot of beeps or a splash screen. If there is a password for the setup utility, you'll need to enter that password. If you reach the Windows lock screen or the desktop, you missed the timing. Under Windows 10, go to the power icon in the Start menu (on the lower left). Press shift and click Restart. You will see an option for entering the BIOS on restart. Select this and wait. Once in the Setup utility look for the boot menu. You can change the order of the list. Press the correct buttons for save and exit to boot to the desired device.

I hope this helps.

(Note: some wireless keyboards may not work in the setup utility. Make sure that a wired keyboard isn't plugged into a USB 3.0 port if you need to load a USB driver to enable the port.)

2.As soon as you identify the BIOS setup key, strike it rapidly and repeatedly (while the booting is on) till the time you enter BIOS setup menu. You may get just a few seconds to do this. If you are not able to enter BIOS setup menu by pressing the key repeatedly, reboot your system and follow the same steps again to enter BIOS setup menu.
Note: BIOS menu do not support mouse input. Hence, you will have to navigate through the menu using the arrow keys on your keyboard.
3.Once you enter BIOS setup menu, you can change the date of your system by going to "System Date" option. This option is generally located in the "Main" section of the menu.
Important: The layout of BIOS menu varies from manufacturer to manufacturer but most of them share a few common settings. If you are not able to detect "System Date" option in the "Main" section of the menu, you may need to look into other sections to locate the option.

Try removing both memory sticks and then booting up with just one installed. The bios should notice a shift in the amount of memory and prompt you to enter the bios.

Let me know if that works.

press hard disk and boot the windows

You need the windows CD to install windows, insert the cd in drive and press enter when asked to press anykey to start from cd.
if you don't get the start from cd and the windows setup doesn't start then most likely your computer is not set to startup from a cd drive, look in the cornerts of your computer screen look for boot menu or press this to enter setup / bios

you can either use the setup / bios or the boot menu and boot from the cd.

if you use the boot menu, make sure the cd is in the drive and select the drive from the list

if you don't find boot menu or it doens't work go into the bios / setup and you will need to change the boot order to include the CD drive FIRST before hdd or floppy. consult your motherboard manual or ask me if you need help in the bios.

when you boot your computer it offers you a chance to enter setup... usually del(ete) key or f11. if neither of those work ... watch as you boot up ... it will show you the key to hit to enter setup.
look for boot options... often in the second menu on the left hand side list.
