There is a growing stream of complaints from PC owners on the Microsoft support site regarding older generation AMD processors getting into an “unbootable state” after installing the latest security updates to protect against Meltdown and Spectre vulnerabilities. Microsoft acknowledged the problem and is blaming AMD’s documentation for the unexpected problems.
“Microsoft has reports of customers with some AMD devices getting into an unbootable state after installing recent Windows operating system security updates,” says a Microsoft spokesperson. “After investigating, Microsoft has determined that some AMD chipsets do not conform to the documentation previously provided to Microsoft to develop the Windows operating system mitigations to protect against the chipset vulnerabilities known as Spectre and Meltdown.”
They are now stopping AMD PCs from receiving updates, to prevent PCs into an unbootable state.
Microsoft is working with AMD to resolve the problems with AMD PCs soon. Affected owners will need to visit Microsoft’s support site for fixes to get machines back into a bootable state.
