How do I re-install Monterey

My MacBook Air (Early 2015) has been restarting itself.

I updated all software, still happens.

I sought Support from Apple - seems the best thing to do is re-install the iOS.

I did a SMC reset. Did a NVRAM reset too.

Shut down. Pressed Command+R. It went into Internet Recovery.

Then when I asked it to re-install Monterey - it says cannot find disk.

So I unplugged power cable - nothing else is connected - then repeated shut down and voila - the disk is visible.

tried installing. Failed.

So I thought perhaps there is some disk error.

Tried again, and when there was the Disk found - I tried installing the iOS - but it failed.

I tried again - Shut down, re-booted - went to Disk Utility. Sometimes the disk is there, sometimes its not.

I tried Erase (when Disk could be found). It didnt work.

So I wanted to repair - but it didn’t work either.

So I tried to go into safe mode. Doesn’t work anymore - it just keeps re-starting in a loop.

So now I’m re-starting. And hoping to get into the Disk Utility where it can find the disk and I can erase it so that it’s clean.

I hope that’s the best way for me to do a clean install of the Monterey iOS.

Please advise if there are better ways? Thank you.
