I have MacBook Pro (Mid 2010), previous it has MacOS Sierra.....and I formatted internal hard drive.....so how do I install from usb drive....cause i tried to make my niece 16gb usb drive as a bootable device with MacOS High Sierra but my MacBook Pro does not boot from it
How did you make the bootable USB installer.
You need the Install macOS High Sierra.app, a good quality USB stick (16GBs)
and read the instructions here,
How to create a bootable installer for macOS – Apple Support
When you have created the bootable USB stick plug it in to your mac.
Restart the mac while pressing and holding the option/ alt key.
After a couple of minutes you will see the Startup Manager, select the
USB and press Return.
The mac will restart to the USB, you will see a Utilities panel click on
Install OS and press Continue.
The installation process should start, follow the prompts.

You can use an external drive or secondary volume as a startup disk from which to install the Mac operating system.
I have done all that by using TransMac App cause i formatted my MacBook Pro hard drive and when I start my MacBook does not boot from usb.
You said I should download 'install macos high sierra.app' but in which web
I did take to the tachinician and it was found that the internal hard drive crushed.....so they did some clean up and install a new OS although same OS as was before (MacOS Sierra).
While I wanted to have MacOS High Sierra.....Oooops
Did you start with this file or what?
https://itunes.apple.com/app/macos-high-sierra/id1246284741?mt=12
Try installing this in Safe Mode, but not using Firefox...

Safe Boot, (holding Shift key down at startup).
Just checking, you're holding alt or option key when starting the Mac?
Yes I also do that
What shows when you do that?
It bring me to boot from 'Recovery-10.13.3'
No.....i downloaded .dmg file
Which DMG from where?
MacOS 10.13 gm_(17A326A).dmg I got it from mac-ru.net through BitTorrent
I tried to use usb drive and external drive but my mac book pro does not boot from them.
Let me take it to the nearest technician so I can check the problem
OK, do let us know the outcome please! :)
