High Sierra Recovery Partition creator

I used to SEE "Recovery HD" as a boot option when I pressed the Option key during power on. After I upgraded from Sierra to High Sierra, I do NOT SEE this "Recovery HD" anymore! I thought the upgrade had a hiccup and destroyed the recovery partition.

It turns out even though I do NOT SEE "Recovery HD", it IS STILL there!

Just now I pressed Command + R during power on, and it boot into recovery as before.

So seeing can sometimes be misleading! haha

I am trying to create recovery partition on macbook pro 5.5 (mid 2009->2010).

I currently have multi boot setup with Snow Leopard; El Capitan & High Sierra working.

I had to do modified install of High Sierra due to Apple's non-intended support of this version of macbook pro, but High Sierra works well w/ 8GB RAM & new SSD.

Using Anver's method I get stuck at with error of "bad CPU" that I think has something to do with cross-correlation of existing H/W with 'sanctioned' H/W list accessible to the installer.

I tried using the modified High Sierra installer pkg, but got other error citing it as a "non-Apple" installer.

I don't have the El Capitan installer pkg as I did that as an 'upgrade' from Snow Leopard.

Any suggestions on how to proceed to create a working recovery partition?

Thanks,

David

I have the exactly the problem as daidnik above only on an Early 2008 Mac Pro with High Sierra, any solution to this been found yet?
Thanks

I have just solved this, boot from the modified High Sierra installer, run the macOS post install again, tick the box Recovery Partition Patch, job done you can now boot the recovery partition.
