What is boot menu?

When we turn on our computer, the machine goes through a process known as booting that is carried out automatically. This could be accomplished by the CPU's circuitry, software, or processes that contribute to the computer system. Rebooting a computer is another term for restarting a computer when the electricity is not cut.

A smooth boot may clear RAM to zero on certain computers. Hardware, such as a push-button, or software commands, could start hard and soft booting. When the real-time operating system, which typically includes the operating system and several programs, is reached, booting is complete. The term "boot" refers to a type of footwear.

When you switch on your desktop, a log of your computer/manufacturer laptop appears. That's the end of it. More significantly, before windows loads into RAM, when you switch on the desktop. This period is known as the booting system.

When a computer starts up for the first time, an accessible menu called the Boot Menu. It can boot to various devices, including CDs, DVDs, storage devices, and hard disk drives, as well as a LAN (network). Even if the machine already has an operating system installed, the Boot Menu enables users to load other operating systems or apps. Because the user can select which hardware to use while installing a new OS on a desktop, a Boot Menu is also important.

The moment your desktop or laptop is, the logo is displayed on the screen, and "Press F12" or "Press F2" for the boot menu is presented in the corner. When the key is pressed, a menu will be displayed. This is referred to as the boot menu. The boot menu is where you may change your bios settings.

Boot your computer from a drive or disc

Normally, you start your laptop from the primary hard drive, which is where your OS is stored (like Windows). However, there are times when you will need to boot from a CD, DVD, or USB device, such as when you are performing a recovery application or trying out a new OS like Linux.

You must tell your computer's BIOS to download the operating system from a separate location than normal in order to accomplish this. This can be accomplished in two ways:

  • In the BIOS, you may change the boot order.
  • By reaching a boot menu at opening (It will only boot from either a CD or USB once).

How to access the boot menu in Windows 7

1. Press the Power switch, click the "Shut Down" icon, followed by "Restart."

2. While the system is rebooting, before the Windows logo shows, continually click "F8." You misplayed the hotkey and should try once more if you see the Windows logo. Select the right boot zone before clicking "F8" if you're running a dual-boot computer; most users won't have to worry about it.

3. Mark a selection in the Advanced Boot Options window using the up or down arrow buttons, then hit "Enter" to choose it.

How to access the boot menu in Windows 8

To access the BIOS, go to Settings, then General. Select Restart Now from the Advanced Startup menu. This will bring up the boot menu on your machine.

Holding Shift while clicking Restart is another simple way to get to the boot menu.

What is the boot menu

If your computer can resume Windows properly, you can rapidly access the "Advanced Options" menu with the help of pressing and holding the Shift key while selecting "Restart." This can be done on the sign-in screen (see above) or the Start menu (shown below).

Boot sequence vs Boot Menu

While the machine is booting, a Boot Menu permits the user to select, which boot drive to use. The boot sequence is a BIOS parameter that directs the desktop on how to look at possible boot devices on a desktop or laptop in what order. In other words, the boot schedule is continuously performed every time the desktop boots up without the need for user interaction. To use a Boot Menu option, the user must first enter the Boot Menu by pressing the key and then pick the boot choice.
