It looks that you wiped main drive. What you exactly did?

If you just want a fix. I suggest you.

1) Hold command + R to boot into recovery partition.
2) Install OS from there
3) Perform OS upgrade if the OS installed in step 2 is not HS.

I have tried to put in again my back up but i got an error that the system could not find my disk or something..so i removed the back up and trying to re instal but i can only instal macOS Sierra and it stuck.

Exact same thing happened to me.

Try boot into secondary internet recovery mode. Shutdown, then power back on and immediately hold down the Cmd+ Shift + Alt + R buttons. It will download the Sierra (not High Sierra) recovery, and you should be able to see the drives. You should be able to erase your drives back into normal Mac Journaled HSF format and reinstall sierra.

It can be expect that Apple's server is very busy right now. If the OS (Sierra) download clearly stuck, may be cancel it and start again.

 

[sirio1981]

yeah i did canceled it and start again now it went from 4 min to 3 min and looks like it stuck at 3 min atm..
[doublepost=1506426591][/doublepost]update after 35 min it went from 3min to 2min......WTF.

 

[sirio1981]

been stuck at 2min for 1 hour
[doublepost=1506431382][/doublepost]So i cancelled the downloading cos was stuck at 2min and started over again and in less than 15 min it went to about 1 minute remaining...looks like the download only go ahed when i do a -cancel- and re-download again.

i wanna see how long is gonna sit at -about a minute remaining-

 

[sirio1981]

so after being stuck at 1min for 40 min i did another cancel and re download and now it is stuck at 22 seconds.. looks like the only way to make it work is keeping canceling and re-downloading WTF...how the !@#$

Didn't work i get this error message -could not create a preboot volume for APFS install-

problem solved after calling the call center just by pressing command+alt+r after you turn on the imac and do a system reinstall from there.
