I am new in Ubuntu. This is my first time experience.

Installed Ubuntu 20.04 as dual boot; but, when I turn on computer, it directly opens with Ubuntu. There is no Windows 8 option and here is also no grub bootloader option coming up.

How can I fix this problem?

Open /etc/default/grub for editing (you will probably need to run with sudo for write permission). Edit the following lines:

GRUB_TIMEOUT_STYLE=menu
GRUB_TIMEOUT=3

The first line will show the grub menu on boot, which will hopefully have an option for booting to Windows. The GRUB_TIMEOUT parameter is the number of seconds to wait for a selection before using the default. You could adjust this to your liking.

After you make the change in /etc/default/grub, you will have to run update-grub (again, probably with sudo) to apply the changes. Then reboot and make sure the grub menu appears.

If you get the grub menu to appear, but still do not see an entry for Windows, then I suggest you edit your question to reflect this.
