I can't partition my internal disk

Hi there

I want to partition my internal disk as I want to resintall macOS and there is no disk to select.

Once I click on partition , the + sign is greyed out and cant do anything.

What should I do? Can I restore the internal disk?

Thanks

MacOS not showing up on disk utility I accidentally deleted my MacOS through my bootcamp. I was able to reinstall MacOS and in process had to delete my bootcamp but everything seems to be on the partition I had for the bootcamp so I am missing half of my internal drive. If I reboot in recovery I can see MacOS in the disk utility but it only shows it holds 2GB. How can I get MacOS back on my disk utility with my full capacity?

You may need to boot from a different disk to partition the internal disk.

Some actions on the boot disk are not allowed or are limited.
