Microsoft has introduced boot support for the Resilient File System (ReFS) in Windows Server, allowing insiders to boot the server operating system directly from a ReFS volume. This feature has been made available in the latest Windows Server Insider Preview build after a fourteen-year wait since ReFS was launched in 2012. ReFS can detect corruption early and address issues online, eliminating the need for chkdsk, and supports volumes up to 35 petabytes. It also includes block cloning and sparse provisioning technologies for efficient file management. To use ReFS boot, organizations must install the latest Windows Server vNext Insider Preview with a minimum build number of 29531.1000.260206-1841, format the system partition as ReFS, and ensure UEFI firmware is used.
