First, you need to make sure you have set USB as the boot disk in BIOS. If not, follow these steps to change it:

Step 1. Restart your computer and press and hold F2 to enter the BIOS environment.

Step 2. Find "Boot Options" and select USB-HDD.

Step 3. Make Windows Server boot from USB and save the changes.

If USB boot has been set up, it is also possible that your boot mode is causing the error that the Windows Server cannot boot from USB. When you create the USB with Rufus, it may create to boot in BIOS boot mode (MBR). So you need to change the system boot settings. You may need to create a UEFI bootable USB key. In Rufus, you can use both BIOS and UEFI schemes.

If you need your boot method to be UEFI, then your partition scheme needs to be in GPT format. In addition to using Rufus, you can choose a professional partition management tool to make quick changes. EaseUS Partition Master Server simplifies the process of Rufus. It helps you to create a bootable USB and convert MBR to GPT.
