How to update BIOS for Linux Mint?
I had operating system Windows on my computer Dell OptiPlex 7410. After the installation of the new operating system Linux Mint, Windows was removed. The BIOS update requires an operating system: Windows, Ubuntu, just BIOS. What operational system BIOS should I choose? I was advised not to update the BIOS to break the computer. What should I do?

Hi
Please can you confirm the Make Model and OS, along with any configuration details like touch screen, backlit keyboard, SFF or tower etc etc.
There seem to be variants of OptiPlex All-In-One 7410, so this is generic ....
The file is the same one for W11 or Ubuntu, OptiPlex_7410_1.28.0.exe.

This file format consists of a BIOS executable file. The Universal (Windows/MS DOS) format can be used to install from any Windows or MS DOS environment.
OR
Updating the BIOS from BIOS Boot Menu (independent of operating system)
Note 1: Before updating the BIOS, ensure that you suspend BitLocker encryption on a BitLocker-enabled system. If BitLocker is not enabled on your system, you can ignore this step. For information about how to disable BitLocker, see How to Enable or Disable BitLocker with TPM in Windows at support.dell.com.
Note 2: Do not turn off the power or interrupt the BIOS update process during the update.
Note 3: Your system requires a restart after installing the BIOS. The restart can be deferred but must be completed to ensure that the update is installed.
Installation
1. Copy the downloaded file to a USB drive. You do not need a bootable USB drive.
2. Insert the USB drive into any USB port.
3. Power on the system.
4. At the DELL logo screen, press F12 to access the one-time boot menu.
5. Select BIOS Flash Update in the Other Options section.
6. Click the ... button to browse the USB drive to locate the downloaded file.
7. Select the file and click Ok.
8. Verify the existing system BIOS information and the BIOS update information.
9. Click Begin Flash Update.
10. Review the Warning message and click Yes to proceed with the update.
The system restarts and displays a Flash Progress bar at the Dell logo screen. The system restarts again when the Flash update is complete.
If in doubt please ask.
