Boot up: no entry followed by Apple logo but no progress bar...

I have had this issue after a week or so since updating to Catalina 10.15.4. I don't know if it is connected.

I have to reset NVRAM {CMD+SHIFT+P+R} upon reboot every time to get the progress bar and boot successfully now. I have tried pulling my plug out for 15 secs (from my iMac, not myself!) and restarting with no success either.

I also repaired all drives on Disk Utilities.

Set start up drive in Recovery mode too.

I have had it could be internal battery probs, but nothing solid on that...

Any ideas anyone (I know the issue has been raised before with no solutions)

It is rather annoying and needs a fix from apple really!

Many thanks for any help!

Hmmmm, interesting, in Safe mode see if you can get a report from this for us...

You can save us asking dozens of questions by submitting a report...

EtreCheck is a simple little app to display the important details of your system configuration and allow you to copy that information to the Clipboard. It is meant to be used with Apple Support Communities to help people help you with your Mac.

Pastebin is a good place to paste the whole report if you capture the URL while there…

Workable but harder for me to work with...the Note tool on the bottom of this editor's toolbar, as shown in the image, to copy and paste the output from EtreCheck. In a Reply before you click post, look for this to add longer texts...

It's ok thanks!

I had a few external drives attached and it was having problems with one which I had an old o/s on, so I just took it off and now booting as normal!

thanks anyway

Can you Safe Boot?

Safe Boot from the HD, (holding Shift key down at startup), does the problem occur in Safe Mode?

Yes - same problem - If I reset the NVRAM during the boot then hit shift when it restarts after reset I can get it into safe, but only resetting NVRAM first.
