Find out how to exit your PC’s BIOS safely, save or discard changes, and solve the most common problems step by step.
Have you ever turned on your computer and suddenly found yourself facing a dark screen full of strange text, technical terms, and confusing menus?
Have you tried pressing a few keys, but instead of returning to Windows you felt even more stuck?
Or have you wondered how to exit the BIOS without risking damage to your computer?
This situation is far more common than you might think. Many users enter the BIOS by mistake, maybe after pressing the wrong key during startup, or they end up there after an update, a hardware change, or an abnormal restart. The real problem is not entering the BIOS, but not knowing how to exit it correctly.
The BIOS itself is not dangerous, but changing settings without knowing exactly what you are doing can cause confusion, boot issues, or make it seem like the PC is broken. The good news is that, in most cases, exiting the BIOS is simple and safe if you know how to do it.
In this guide you will find clear and practical explanations on how to exit the PC BIOS, whether you want to save settings or discard changes, with real examples for the main manufacturers and solutions to the most common issues.

What the BIOS Is and Why You End Up There
Before understanding how to exit the BIOS, it helps to know what it is and why your computer shows this screen.
The BIOS (or UEFI on more recent systems) is basic firmware built into the motherboard. It starts before the operating system and checks that the hardware is working properly: disk, memory, keyboard, graphics card.
You can enter the BIOS in several ways:
- by pressing a key such as Delete, F2, F10, or ESC during startup
- after a boot error
- if the PC cannot find the system disk
- after a reset of the default settings
In many cases, users do not enter the BIOS intentionally, but end up there without knowing why. And that is when the question arises: how do you exit the BIOS without causing problems?
How to Exit the BIOS Without Saving
If you entered the BIOS by mistake or only “looked around” without wanting to change anything, the safest choice is to exit without saving.
This option cancels any changes and returns the computer to its previous state.
In most BIOS interfaces, the procedure is similar:
- Find the option “Exit” or “Exit Without Saving”
- Alternatively, press the ESC key
- Confirm with “Yes” or “No Save”
In some cases, you can directly use:
- ESC
- F10 (with a confirmation prompt)
- or select “Discard Changes and Exit”
Exiting without saving is the best choice if:
- you are not sure what you changed
- you entered the BIOS by mistake
- you want to avoid boot problems
Remember: exiting without saving does not damage anything and does not change how the PC works.
How to Exit the BIOS Saving the Settings
There are situations where saving changes is necessary, for example after changing the boot order or restoring default settings.
In this case, to exit the BIOS while saving:
- Go to the “Exit” menu
- Select “Save Changes and Exit”
- Confirm with “Yes”
Many BIOS versions also allow you to:
- press the F10 key
- confirm the save
After saving, the computer will automatically restart and try to load the operating system.
How to Exit the ASUS BIOS
On ASUS BIOS systems, very common on desktop PCs and laptops, the interface may be “EZ Mode” or “Advanced Mode”.
To exit correctly:
- Press F10
- Select “Save & Exit”
- Confirm with “OK”
To exit without saving:
- Press ESC
- Choose “Discard Changes and Exit”
The ASUS BIOS screen is intuitive, but if you are unsure about the changes, it is better to discard them.
How to Exit the MSI BIOS
The MSI BIOS often uses a modern graphical interface.
To exit and save:
- Press F10
- Confirm saving
To exit without saving:
- Go to “Exit”
- Select “Exit Without Saving”
Here too, if you have any doubts about the changes, exiting without saving is always the safest option.
How to Exit the Lenovo BIOS
On Lenovo PCs, especially laptops, accessing and exiting the BIOS may vary slightly.
In general:
- Press F10 to save and exit
- Or press ESC to go back
- Confirm when prompted
Some Lenovo models show a very simple menu: do not worry, the logic is the same.
How to Exit the Gigabyte – AORUS BIOS
Gigabyte and AORUS motherboards use an advanced UEFI BIOS.
To exit:
- Press F10
- Confirm “Save & Exit”
To discard changes:
- Go to “Exit”
- Select “Discard Changes”
The Gigabyte BIOS screen offers many options, but there is no need to touch them unless you know exactly what you are doing.
How to Exit the “Windows BIOS”
Sometimes it looks like you are in the BIOS, but in reality you are in Windows advanced startup settings.
This happens when:
- Windows does not start correctly
- you have forced several restarts
- you opened the recovery menu
To exit:
- Select “Continue”
- Or “Exit and continue to Windows”
- The PC will try to load the operating system
This screen is not the real BIOS, but a Windows safety feature.
If There Are Problems: What to Do If the PC Always Returns to the BIOS
If, after exiting, the computer always returns to the BIOS, it is important to clarify one key point right away: the problem is not exiting the BIOS, but the boot process itself. In practice, the PC enters the BIOS correctly because it cannot find what it needs to continue and load the operating system.
The most common causes of this behavior are varied and often related to hardware or boot settings. For example, the boot drive may not be detected correctly by the motherboard, perhaps due to a loose cable, a faulty SSD, or a failed update.
Another frequent cause is an incorrect boot order, which makes the computer look for the operating system on the wrong device, such as a USB stick or a secondary drive. In some cases, the issue may be caused by a damaged operating system or an automatic reset of the BIOS default settings.
In these situations, the first thing to do is check in the BIOS screen that the main drive is actually visible. Then, make sure the boot order is correct and that the drive containing the operating system is set as the first option. If you are unsure, you can try restoring the BIOS default settings, a safe operation that often fixes problems caused by incorrect configurations. If the PC still keeps returning to the BIOS, it is advisable to contact a technician or the manufacturer’s support service.
Remember: the BIOS is not the enemy. In most cases, it is simply indicating that something earlier in the boot process is not working as it should.
Conclusion
Knowing how to exit the BIOS means removing a lot of stress. You do not need to be a technician or an expert: you just need to know the right steps and understand when to save changes and when to discard them.
Whether you are trying to exit the BIOS on an ASUS, MSI, Lenovo, or Gigabyte PC, the rules are always very similar. With calm, attention, and a bit of awareness, the BIOS stops being scary and becomes just another screen in the startup process.
