An administrator is attempting to start a server from a bootable Linux disk but instead the server boots into Windows. Which of the following is the MOST likely reason for this?

There is no technical requirement for a system to boot to Windows first before booting into Linux from a separate medium.

OS settings are configured after the OS has booted; they do not prevent a system from booting from a separate bootable disk.

The BIOS (or UEFI firmware) controls the sequence in which storage devices are checked for a bootable operating system. If the boot order is set to prioritize the internal hard drive with Windows over the removable media (CD/DVD drive or USB port) containing the Linux disk, the system will bypass the Linux disk and boot directly into Windows. To fix this, the administrator must access the BIOS/UEFI settings and adjust the boot order.

Whether a Linux disk is 'supported in a Windows environment' is irrelevant to the system's ability to boot from it, as the BIOS/UEFI handles the initial boot process independently of the installed OS.
