Windows 8 Secure Boot blocks Android and other operating systems

September 24th news, according to foreign media reports, according to Microsoft pointed out that Windows 8 certified 64-bit hardware will be forced to take some security measures to block the installation of other operating systems, such as Linux, until the software is considered Trusted to install.

Windows 8 does not boot using the BIOS. The 64-bit version of Microsoft's latest operating system must use UEFI (Unified Extensible Firmware Interface) and enable Secure Boot.

In a video explaining the new launcher, Microsoft project leader Arie van der Hoeven said that the decision to force UEFI is based on security considerations; the company hopes to reduce bootkits, rootkits and ransomware. The risk of booting the class.

But in order to protect Windows 8, the safe boot process will make it harder to install other operating systems or another set of Windows, because any software and hardware executed on the system must go through Microsoft or OEM vendors. The visa can only be executed.

If there is no visa, the user must enter UEFI to disable the secure boot in order for the firmware to prevent other operating systems from starting.

While it's not sure if Microsoft will prevent vendors from providing firmware support to turn off this feature and execute undocumented code, it's certain that many systems will offer a shutdown option when shipping.

Linux can also create its own visa key. This feature is called self-visa, but it still has to include this key in every OEM or Microsoft firmware.
