macOS boot entry disappeared after trying to re-partition through Disk Utility

[huijkkkk97]

Yes, correct.

I did it but didn't notice any difference. I've uploaded my USB drive's EFI.

Your previous PR Files and the current one is different. The reason why you still have the verbose is because you have the verbose mode is still present in your boot arg and the WiFi isn't working because you're injecting several IO80211 kexts which you shouldn't.

I think you've misread my posts. The PR files I sent are those from my normal macOS installation. The EFI folder I just sent is the partition of my USB drive, because (as I said at the beginning) there's no boot entry on my PC and it's the only way I can boot to my macOS.

To make sure we're on the same page, currently the issue is you cannot boot via your Internal Drive but can boot through the USB EFI. Is that correct?

Exactly.

 

[EliteMacx86]

Exactly.

Boot using your USB. Make sure to reset NVRAM twice first.

Provide Disk Utility screenshot and also post the output of diskutil list in Terminal.

You could have just attached the output from the Terminal.

So, it seems like there is Linux installed on the disk0 i.e Samsung 840 EVO.

Can you boot into Linux?

Provide the EFI from ESP.

I think you read my original post before I edited it. As mentioned previously:

Okay, so I have 3 disks: 1st contains the home partition of Linux and all the macOS (Big Sur) partitions, 2nd contains the root partition of Linux + Linux EFI partition and the 3rd contains Windows partitions. I've been using macOS for a few months without problems.
[...]
I don't really use my Linux that much, so I decided to just delete all the partitions related to it on both my 1st and 2nd disk, but there's still no macOS boot entry.

I can't resize my macOS partition, so I just deleted the Linux-related partitions using GParted.

Likely possible.

Well, the partition has not been deleted yet. However, you can delete the partition using the following way.

Select Samsung SSD 840 EVO 250GB Media and click on Partition.
Except for the macOS partition, select and delete the Linux partition. Once deleted, click on Apply and it will be resized automatically.

If you do not have the clear idea, provide a screenshot for the above steps to assist.
