How can I upgrade or install Windows 11 on surface book 1st gen?

You can use the WinBoootMate app for installing Windows 11 on unsupported hardware such as surface book 1st Gen. It is widely regarded as the best tool for installing Windows 11 on unsupported PCs because it simplifies the bypass process significantly.

Unlike Microsoft's Media Creation Tool or manual registry edits, WinBoootMate has a built-in feature that automatically removes TPM 2.0, Secure Boot, and CPU checks from the Windows 11 ISO. This means users don't need to manually edit registry keys or use command-line workarounds to install Windows 11 on surface book 1st gen. This can reduce the risk of errors and saving time. The tool also ensures that the modified ISO remains clean and bootable, making the installation process as smooth as possible.

Another advantage of WinBoootMate is its flexibility in creating bootable drives for both UEFI and legacy BIOS systems. Many older PCs, including the Surface Book 1st Gen, may have firmware limitations, but WinBoootMate optimizes the USB drive to work seamlessly across different configurations. Additionally, it allows users to choose between NTFS (for UEFI with CSM) or FAT32 (for pure UEFI)
