I have the following master branch structure:

WrongCommit1-->WrongCommit2-->WrongCommit3       master
              /
             /
GoodCommit---                                    master

I'd like to "re-start" the master branch from the GoodCommit, do some changes and forget the Head ending with WrongCommit3.

How is it possible to do in git?

I presume GoodCommit is for you a SHA-1

git checkout master
git reset --hard <GoodCommit>
git push --force origin master

Optionally, you can remove the wrong commits from the history

git gc

Not sure if this is the 'proper' way to do it, but it works for me:

1. Revert back to GoodCommit using git revert <id> or with some GUI application like GitHub Desktop.
2. Force push into master with git push --force origin master, or again with that application.

This sets your machine back to the GoodCommit, then forcibly overrides any chagnes and places it into the top of master.
