The latest 3.18 pre-release (beta) version of Rufus, the popular bootable USB media creation software, adds the ability to bypass Windows 11 system requirements for in-place upgrades too.
Earlier, with version 3.16 Beta 2, Rufus had already received the option for bypassing the stringent system requirements for Windows 11 with the “Extended” installation feature. Though, the option was only available for clean installations. However, now with Rufus 3.18, the feature can be availed for in-place upgrades too.
Rufus 3.18 beta also fixes another Windows 11 related bug that broke the “ISO → ESP creation” feature. The bug (#1855) would prevent the creation of EFI system partition (ESP) on Windows 11 devices and throw an error code “0xC00305B4”.
