Dual Boot Macos Catalina And Ubuntu
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.
Dual Boot Mac Os Ubuntu 10.13
This is because the Ubuntu boot disk (USB device or a DVD) is set as the boot device. In short, Ubuntu won't boot after install because the disk is still present. So, eject the disk, and ensure the correct boot device is selected. Checking the boot device can be done in your system UEFI/BIOS, or if available, the boot order menu. Both of the boot managers available to use can handle the dual-booting process; they can even handle more than two OSes, but the Mac's boot manager won’t recognize the Ubuntu OS without a bit of fiddling, and the GRUB boot manager isn't particularly easy to use. If you want to install Ubuntu as a dual-boot option with Windows, select Install Ubuntu alongside Windows. Next, choose where Ubuntu should be installed. The installer will recommend a configuration that allocates a reasonable amount of space to Ubuntu while giving priority to the size of your Windows partition.
