[SOLVED] High Sierra Install Issues

[mukulgusain22]

Hi folks,
I shutdown my MacBook Pro 2012 while installing the macOS high sierra. Since then the laptop is not booting up. A code error screen pops up while restarting and the loop continues. I have tried everything that the google threw at me but to no avail. The data back up is also not there and I can't afford to miss on it.
Can someone help out a man in need!!

Have you tried booting into recovery mode? Then you can try to reinstall. If it won't boot into recovery mode. Do an SMC reset and PRAM reset. Then boot into recovery mode.

List of key combos for different boot options including the PRAM reset, recovery mode, hardware diagnostic and Internet recovery. Any option you choose must be performed before the startup chime.
