I am using the key-combination Shift+Option+Command+R right after power on. MacBook boots up, and allows me to connect with my wifi successfully. As expected, a spinning globe comes on the screen and takes around 10 mins. I am assuming it's downloading here the OS version that came with my MacBook, but once it's finished, I receive error having globe with alert symbol as attached

The first thing I'd suggest is resetting the PRAM twice in a row and then attempting the installation.

I saw this on another forum and since it's easy and non-destructive it's worth a shot.

I did that using Command_Option+P+R... Heard startup chime two times.. then turned off MacBook immediately by holding long the power button... again turned on and repeated the command till i heard startup chime again two times.

But this didn't resolve issue? Did I reset PRAM correclty?

I would probably contact Apple Support as instructed. This is a basic function on a recently-purchased computer (since it shipped with Catalina). Have Apple make it work.

Please update here as well with your outcome.... Not sure why Apple was in hurry to release Big Sur if they didn't test it properly. Lot of people are not happy.

I had a similar problem.
I believe the fix is to use command+R on restart to reinstall rather than using Shift+Option+Command+R

Sorry, I was suggesting you contact support. It's what I would do in your situation.

In addition to @yukari's helpful find...
macOS 10.15 or later: Click Apple ID, click iCloud, then deselect Find My Mac. Enter your Apple ID password, then click Continue.
I'd suggest logging out of iCloud entirely...
Apple said:
If you're using macOS Catalina or later, choose Apple menu  > System Preferences, then click Apple ID. Select Overview in the sidebar, then click Sign Out.
Apple suggests doing both in that order. However, from what I recall, when logging out of iCloud, macOS alerts you that Find My Mac will be disabled.
