Build 29550 Bare Metal ReFS Boot: Server Roles installation fails with 0xc004000d and/or 0x800f0922
When installing Windows Server Build 29550 on Bare Metal with the OS drive (C:) formatted as ReFS, the installation of core Server Roles (DHCP, Hyper-V, DNS, Windows Server Backup) fails consistently. Error returned by PowerShell (Install-WindowsFeature) and/or Server Manager: 0xc004000d (One or several parent features are disabled). CBS.log shows TiWorker failing with [HRESULT = 0x800f0922 - CBS_E_INSTALLERS_FAILED]. Troubleshooting done: Same ISO on KVM (formatted as NTFS) works perfectly. Same hardware, formatted as ReFS on older Build 29531, worked perfectly. "Leaf" features like Media Foundation install fine, but complex roles fail. sfc /scannow did not find any integrity violation DISM RestoreHealth fails with 0x80004005 Conclusion: There is a CBS / Hard Link regression when reading the Component Store (WinSxS) on a ReFS boot drive in build 29550.
