Recovering from hard reset in Git - Step-by-Step Execution

Process Flow - Recovering from hard reset

Start: Hard reset done

↓

Check reflog for lost commits

↓

Identify commit hash to recover

↓

Use git reset or git checkout to restore

↓

Verify branch state restored

↓

End

After a hard reset, use git reflog to find lost commits, then reset or checkout to recover them.

Execution Sample

Git

git reflog
# find commit hash

git reset --hard <commit-hash>
# restore branch to commit

Shows how to find lost commits after a hard reset and restore the branch to a previous state.

Process Table

Step	Command	Action	Result
1	git reset --hard HEAD~2	Reset branch 2 commits back	Branch moves back, commits lost from current view
2	git reflog	Show recent HEAD changes	List of commits including lost ones with hashes
3	git reset --hard abc1234	Reset branch to lost commit abc1234	Branch restored to lost commit state
4	git status	Check current branch state	Clean working directory, branch at recovered commit

💡 Branch restored to lost commit using reflog and hard reset

Status Tracker

Variable	Start	After Step 1	After Step 3	Final
HEAD	commit xyz7890	commit uvw4567 (2 commits back)	commit abc1234 (lost commit)	commit abc1234 (restored)

Key Moments - 2 Insights

Why do lost commits still appear in git reflog after a hard reset?

Because reflog records all recent HEAD movements, including resets, so lost commits are still referenced there (see execution_table step 2).

What happens if you reset to the wrong commit hash from reflog?

You will move the branch to that commit state, which may not be the desired one. Always verify the commit message or date in reflog before resetting (see execution_table step 3).

Visual Quiz - 3 Questions

Look at the execution table, what command shows the lost commits after the hard reset?

A git reset --hard HEAD~2

B git reflog

C git status

D git checkout

💡 Hint

Check step 2 in the execution_table where lost commits are listed.

At which step is the branch restored to the lost commit?

A Step 1

B Step 2

C Step 3

D Step 4

💡 Hint

Look at the action and result columns in step 3 of execution_table.

If you skip git reflog and try to reset directly, what is likely to happen?

A You might reset to a wrong or unknown commit

B You recover the lost commits anyway

C Nothing changes, branch stays the same

D Git will automatically find the lost commits

💡 Hint

Refer to key_moments about verifying commit hashes before reset.

Concept Snapshot

Recovering from hard reset:
1. Use 'git reflog' to see recent HEAD changes including lost commits.
2. Identify the commit hash to recover.
3. Run 'git reset --hard <commit-hash>' to restore branch.
4. Verify with 'git status' that branch is restored.
Reflog keeps history even after hard reset.

Full Transcript

When you do a hard reset in git, you move your branch pointer back and lose commits from the current view. But git keeps a history of all recent changes in something called reflog. You can run 'git reflog' to see all recent commits including those lost. Find the commit hash you want to recover, then run 'git reset --hard <commit-hash>' to move your branch back to that commit. Finally, check with 'git status' to confirm your branch is restored. This way, you can recover lost work after a hard reset.
