Hi, I’m quite new to ubuntu and am undergoing issues. I tried to dual boot ubuntu on my 2013 Macbook air by using a usb. I followed the instructions that the ubuntu site has provided in order to do so (via https://ubuntu.com/tutorials/create-..os#1-overview;https://ubuntu.com/tutorials/install..top#1-overview), however I’m now having trouble accessing macos. When I enter the boot screen whenever I restart my laptop and hold the option/alt key the macos disk is no longer there and all disks(3 disks) simply read as EFI Boot. When I select the the disk that was originally macos it reads a message on the screen and then redirects me to ubuntu
The message reads as following:
Failed to set MokListRT: Invalid Parameter
Could not create MokListRt: Invalid Parameter
Importing MOK states has failed: import_mok_state() failed
: Invalid Parameter
Continuing boot since secure mode is disabledSystem BootOrder not found. Intia
Lizing defaults.

According to what I have read online it seems I have overwritten my mac os operating system, which I interpret as macos no longer exists on my laptop and I have likely lost any data that is connected to it. I’m fine with the lost data however if there’s any way that I can retrieve it that would be great, however my main concern is getting macos back on my laptop. I apologize for the hassle but i'm rather unfamiliar with linux and general programming terminology and concepts so if a basic rundown with simplified terms can be provided that would be greatly appreciated. Thanks.
