No bootable device insert boot disk and press any key problem, keyboard not working accidently deleted macintosh hd and windows os

Hi guys,

I'm using a 15" mid 2012 mac-book pro. My dual boot wasn't working that well because there wasn't enough storage so I thought that I could wipe my mac. So using, command-r I deleted all my macintosh HD + data and windows bootcamp files. I restarted my computer and "No bootable device -- insert boot disk and press any key" popped up on the screen. I've spent the whole afternoon researching about what to do. I've tried the command-r and holding alt/option but nothing seems to be working. I think my keyboard isn't working either. I've also tried downloading windows 10 from Microsoft onto a usb to try and recover my device. I'm not sure if my backups are still on my computer anymore. Please help!

MacBook Pro 15", macOS 10.15

Yes.

And where can I find the download for the Apple CDN?

Instead of a wireless connection, which can be slow and prone to corruption, use Command+Opt+R and try to boot into Internet Recovery.

Your Local Recovery is either corrupt or unviable, and the error code is indicating that your Mac cannot reach Apple Internet Recovery servers. Do you have a second Mac?

Before you get a second Mac involved, if Internet Recovery works, we should use it. Consider using a wired connection, instead of a wireless connection for Internet Recovery. You need to download about 2+ GB from Apple CDN to be able to bring up Internet Recovery and wireless can be slow.

Also, look at Transfer files between two Mac computers using target disk mode - Apple Support and check if you have the appropriate cables, if needed.

Click on Utilities -> Terminal. Can you post the output of

diskutil list

when in Recovery?

Yes, but you will need appropriate cables. See Transfer files between two Mac computers using target disk mode - Apple Support for reference.

I'm not quite sure how to do that. I've tried going into recovery mode but nothing happens, if anything, it opens to the screen below faster. It seems like my keyboard isn't working except for the power button.

I reset the NVRAM and restarted my mac. I held alt/option to see if my disks are there. There were no disks but after restarting and holding command-r, I went into internet recovery. After waiting for a bit, an error sign has come up with, apple.com/support -2002F. Do you know what -2002F is?

sorry I meant I restarted my computer and held options, put in my wifi password then internet recovery came up as an option, instead of there being no drives, internet recovery was the only thing that came up.

I'm trying the internet recovery again. My mum has a second mac. I've already tried getting catalina on a USB but I got pretty confused at the instructions on apple. Internet recovery says apple.com/support -2002U this time

How do I use a wired connection? Would that just be using a cable to connect the computer to the modem? And where can I find the download for the Apple CDN?

Just did the internet recovery, connected with ethernet cables, but there was still an error. Is it possible that I can transfer a copy of MacIntosh HD from another mac onto my mac?
