If a server is unable to boot from a USB device, what should be done?

Reconfiguring the boot order is a critical step when a server cannot boot from a USB device. The BIOS or UEFI firmware of a server dictates the sequence in which devices are checked for bootable media. If the USB device is not configured as the primary boot option, the server may attempt to boot from other devices, such as the hard drive, which can prevent it from launching the operating system from the USB.

When addressing boot issues, it's essential to ensure that the USB device is set at the top of the boot priority list. This action often resolves the problem because it directs the server to read the USB device first. Additionally, confirming that the USB device is properly formatted and contains a bootable image is important, as these factors could also affect booting success.

While replacing the USB device or checking its cable may be necessary if you suspect a hardware fault, these actions are not the first steps to consider when booting issues arise. Similarly, checking for hardware compatibility can be important, especially in specific circumstances, but it assumes there is already a broader understanding of the hardware rather than focusing on the immediate solution of booting order configuration.
