Only one of the two processor cores is recognized by Linux Mint on my laptop
My computer seems to have only one of the two processor cores operating.

So; to be able to boot the computer correctly I am forced to make certain modifications to the grub file in the path: etc/default/grub I made the following necessary changes:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset nolapic acpi_osi="Windows 2006""
And after this I updated the grub with sudo update-grub
Since apic is linked to the processor management and to be able to boot I have to disable it by manually entering changes to the GRUB file. I think those changes I have set, have to do with the deactivation of one of the CPU cores.
What can I do to make both cores of my processor work instead of just one?
