"Windows 8認證品牌機可能不支持啟動Linux。"根據新的規定，Windows 8認證的機器可能將阻止部署Linux。Win 8要求機器用統一可擴展固件接口（UEFI）代替BIOS。EFI正逐漸取代長期使用的BIOS固件，它兼容Windows，支持全局唯一標識分區表（GUID Partition Table），OS X/Intel和Linux 2.6。
EFI和UEFI 規格對Linux來說沒什麼問題，但問題是微軟要求win8認證客戶機支持安全啟動，啟動進程內的所有固件和軟件都需要可信CA簽名，顯然微軟試圖鎖定啟動進程，阻止安裝無簽名的第三方系統如Linux。
- Current issues with boot
- Growing class of malware targets the boot path
- Often the only fix is to reinstall the operating system
- UEFI and secure boot harden the boot process
- All firmware and software in the boot process must be signed by a trusted Certificate Authority (CA)
- Required for Windows 8 client [emphasis mine]
- Does not require a Trusted Platform Module (TPM)
- Reduces the likelihood of bootkits, rootkits and ransomware
