[Solved] Installation: Dual boot Debian 12 on Macbook Pro 2019, with Intel & T2

[aluva]

After upgrading from Catalina to Ventura, it started the issue of Volume Hash Mismatch. Even after several upgrades, the issue continued. Then, I re-installed Ventura. Still the problem persists.

Objective: Install Debian 12 (weekly) on Macbook Pro 2019 with Intel chip & T2: I followed this approach: https://www.debugpoint.com/debian-12-installation/

2. After installation, when rebooted:
It was not shutting down

3. When rebooting, even with Option key:
It just shows boot option for MacOS ONLY.

Can someone help me, please?

A starting point: boot Debian installation media into installed system, or into rescue mode, and report here input/output from efibootmgr -v.

@mrmazda, thank you!
I could some how manage to resolve the issues.
I believe, it was because of partitioning problem for dual booting.
Now, the new issue is that there is NO WiFi..!! I made a fresh posting on this.
