What to do now? please help (OPTION does not work anymore, Command + R also does not work anymore). Now i have Linux Manjaro and is working fine under MacBook Pro hardware!

Thanks and BR,

Have you tried Shift-Option-Command-R?

Of course, all Shift and Other combinations all tried it but now my MacBook Pro does not sense any MacOS USB drive!
That's why I am posting here, because I have a very strange situation!

Well, since your Linux install works just create a MacOS Bootable USB.

Thanks a lot. Great. I already have a MacOS Catalina 10.14.6 USB drive created by my friend macBook Pro and it worked for him, to boot it.
In my machine does not sense it at all. Of course linux can see and view the contents of this USB drive and it's not damaged at all
Bottom-line: looks like my MacBook Pro BIOS does not see my USB drive for some reason, two weeks back this was working fine!
Any new hints please?

Is the HDD partitioned? If the Linux install is taking up all of the hard drive and is formatted for that, that's possibly why. You would need to get the HDD or at least a portion of it back to Mac OS Extended format (HFS+).

Very good tip. Tomorrow i will resize it using Linux GPartd and update you, if it works or
Not!! Thanks a lot for your kindness and time

Good news: i went today to apple support, even for them it was a big suprise the whole issue! Keyboard hardware issue and they fixed it, that’s why any bootable USB drive was not booting properly. Anyhow i have cleaned new Big Sur v11: fast and really awesome, i still like Linux as it is more customized op system than rigid and harsh MacOs!
Thanks for the help and this thread can be closed foe gooooods
