Though, this issue appears with very less frequency.
The doubt in my mind is how boot process starts without the presence of bootloader in sda1.
I am not able to perform journalctl -xb as this issue do not boots the system up and when I get the correct boot order, everything starts from recovering journal. I am also not able to reproduce again on my will on the system.
How should I proceed ?

The system won’t boot up if the process went to booting from /sda1. I need to perform Kresimir’s tip magic SysReq key many times in order to get correct boot drive, though chances of happening from this method is very low.
I am only left with force poweroff in order to get the correct boot drive.
The doubt is that I cannot confirm whether your suggestion had fixed issue or not, as this do not happen frequently, rather it happens once in 60-70 boots, or more.

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.
Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no): YES
