I am trying to install high Sierra on a 2014 MacBook pro. El Capitan. I backed it up to a 1terabyte external hard drive with time machine. The installer is running on a loop.
I need specific and clear instructions.
Not a happy camper right now.

File system verify or repair failed.
This would indicate a corrupt hard drive. Boot into Recovery Mode and run Disk Utility > First Aid. If it reports errors run it until no errors reported or until it reports the drive could not be fixed. Then try the install again.
Hold command-r keys while booting.
How do I boot into recovery mode? I have tried holding shift while the computer starts. I did not see any option that could lead me to disk utility.

First aid process has failed. If possible back up the data on this volume.
Click done to continue.
Your hard drive is failing/failed. You'll need to have it replaced.
