57321: Acronis True Image: "This kernel requires the following features not present on the CPU: pae" Error


  1. You use Acronis bootable media or run an operation that requires reboot, for example, recovering system partition or cloning.
  2. The operation fails with error like:
    This Kernel requires the following features not present on the CPU: pae – unable to boot – please use a kernel appropriate for you CPU.


PAE is a processor feature that enables x86 processors to access more than 4 GB of physical memory. If the processor in your computer does not have this feature, you won't be able to boot it with Acronis bootable media.


We have developed a custom media, which does not require PAE. Please contact Acronis Customer Central and request the media.

In Acronis True Image 2020, PAE is disabled by default in Linux-based bootable media. If you have an active Acronis True Image Advanced or Premium subscription, you can upgrade to the latest version for free.
