Islamabad, Aug 22: Microsoft’s latest security upgrade is causing issues for Linux and Windows computers.
The upgrade, which was made available last week, was created to address a flaw in the popular open-source Linux boot loader GRUB. Despite not being designed with dual-boot systems in mind, a lot of users have complained that the patch keeps their Linux installations from booting properly.
After a recent Microsoft security update, many users of dual-boot systems—systems that run both Windows and Linux—are reporting boot issues. The patches that are causing problems impact several Linux distributions, such as Ubuntu, Debian, Linux Mint, Zorin OS, and Puppy Linux, are meant to fix a flaw in the GRUB boot loader.
Many users have reported seeing error warnings like “security policy violation” and “something has gone seriously wrong” when trying to boot into their Linux installations, according to Ars Technica. Numerous people have reported these issues on websites like Reddit and Ubuntu forums.
Despite Microsoft’s claims to the contrary, a recent security update that was meant to fix a GRUB boot loader vulnerability has unintentionally affected dual-boot computers. The update was created to stop hackers from taking advantage of a vulnerability that let them get around Secure Boot, a vital security feature that keeps malicious firmware from loading during startup on both Linux and Windows.
Microsoft had before said that PCs set up for dual-booting Windows and Linux would not receive the upgrade, which uses the Secure Boot Advanced Targeting (SBAT) technique. The update “should not affect these systems,” according to the corporation. This assertion is refuted by a large number of user reports, which show that the upgrade is really causing boot issues with dual-boot configurations.
