[mahesh2150]

Hi

What i did?

1. I entered disk utility. i saw only Macintosh HD. I erased it and chose APFS.
2. After closing disk utility, i clicked reinstall and followed the instructions.
3. I got error. Something about preboot.

I restarted.

It started internet recovery.
Now, my partitions are different.
Which one should i erase and reinstall mac?
Please tell me the steps.

Can you still boot your MBA? If so, create a bootable USB installer, https://support.apple.com/en-us/HT201372, from whichever macOS version you can download to your Applications folder. Or, make an appointment at the closest Apple Genius Bar.
