# UEFI

A short guide for installing the uefi bios.

**Step 1: Prepare**

* Save your work.
* Restart the PC.

**Step 2: Enter BIOS/UEFI**

* Press the key to enter BIOS. Upon restarting the system, you often need to press one of the following keys (usually F2, Delete, Esc, or F10). A prompt may appear on the screen indicating which key to press.
* Open the BIOS/UEFI settings. If you successfully pressed the correct key, you will enter the BIOS menu.

**Step 3: Find UEFI Settings**

* Look for the "Boot" or "Boot Options" tab. In some systems, UEFI settings may be located in different sections, such as "Advanced" or "System Configuration."
* Select the boot mode. Find the option related to the boot mode (usually called "Boot Mode," "UEFI/Legacy Boot," or something similar).

**Step 4: Change Mode to UEFI**

* Change the mode to UEFI. If the "Legacy" or "CSM" option is selected, change it to "UEFI."
* Save the changes. Typically, this requires pressing the F10 key and selecting "Yes" to confirm.

**Step 5: Reboot and Verify**

* Restart the computer. After saving the settings, the system will reboot.
* Check the boot settings. Ensure that the system is booting in UEFI mode. You can do this by entering “msinfo” in the start menu and checking the "BIOS mode" tab.

**Tips**

* If BIOS/UEFI does not open, try using different keys during boot or check the documentation on your device manufacturer's website.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://hackseller.gitbook.io/hackseller/bios/uefi.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
