Zorin OS Installation Issue

Hello,

Following an issue with Windows 10 that I can no longer launch on my computer, I have decided to turn to Linux, particularly Zorin.

Unfortunately, when I try to proceed with the installation, I get this error message:

 Partitions 2, 4 have been written, but we have been unable to inform the kernel of the change, probably because they are in use. As a result, the old partitions will remain in use. You should reboot now before making further changes.

I have done some research before coming to this forum, which has not been conclusive. I am attaching a Boot-info here so you have more information.
