Immediately after pressing the power button, repeatedly tap the F2 key (or, for some models, the Del key) until you see the BIOS screen.
If you miss the timing, simply restart your laptop and try again.

Navigating the BIOS/UEFI Menu

Once you are in the BIOS/UEFI settings, you’ll find a series of options and configurations.

Boot Sequence Settings:
Use the arrow keys to navigate to the “Boot” tab.
Here, you will encounter the boot order list. Typically, it shows your hard drive as the first option.
Change Boot Order:
Select the USB option from the list.
You might need to move it to the top of the boot order using the keys specified on the screen (usually F5 or F6).
Save and Exit: After configuring the settings, find the “Exit” tab, select “Save Changes” and exit. Your system will restart.

Starting from USB

Upon rebooting, your Dell laptop should automatically recognize the USB drive and start the boot process from it.

If prompted, follow the on-screen instructions to proceed with the installation or recovery process.
If there are issues, double-checking the boot sequence and the USB drive might resolve them.

Troubleshooting Common Issues

While the process of booting from a USB is straightforward, sometimes issues may arise. Let’s look at a couple of common problems and solutions.

USB Drive Not Recognized

If your Dell laptop fails to recognize the USB drive, consider the following steps:
