I have downloaded an evaluation iso for Windows server 2022.

Hello Mohammad Ali,

This error almost means the Windows Preinstallation Environment (WinPE) lost connection to the USB drive immediately after booting. This commonly occurs for two reasons:

1. The server's Secure Boot is blocking the custom UEFI:NTFS bootloader that Rufus uses to read large ISO files.
2. The default Windows Server 2022 media lacks the specific USB or storage controller drivers required by the newer Dell T160 motherboard.

Please try following steps:

Method 1: Use Dell Lifecycle Controller

• Insert your USB drive and reboot the server.
• Press F10 during boot to enter the Dell Lifecycle Controller.
• Click on OS Deployment and follow the wizard. The server will automatically inject the proper drivers into the Windows installation sequence so the USB drive remains readable.

Method 2: Modify BIOS and Rufus settings

If you prefer to boot directly from the USB, go into the Dell BIOS and temporarily Disable Secure Boot. Re-create the USB in Rufus making sure the Partition scheme is set to GPT, Target system is UEFI (non CSM), and File system is NTFS.

Please reply back if you need further assistance.

I have downloaded the ISO file from Microsoft twice and created a USB device for installation. The error remains the same.
