ApolloOS R43 and Vampire Boot

Hi there. I hope you can help me to solve this mystery with the booting process of ApolloOS from an SD card installed at the Vampire V2 using Vampire Boot at a Compact Flash.

I followed the steps at the tutorial 1 of the Vampire Boot repo (https://github.com/henrikstengaard/vampire-boot) in order to prepare the HDF image with the Workbench required files, using UAE. Then I dumped the HDF image into a Compact Flash connected to the IDE port through an adapter, and a Sandisk 64GB SD card with ApolloOS image r43 dumped to it using Etcher for OS X (I previously tried with a Sandisk 32GB SD card, but Etcher told me that the 32GB image couldn't fit... it sounds like it wouldn't for a few thousand bytes.

Then, when my Amiga 600 boots with my Vampire V2 on it, I can see the menu that appears at step 6 of such tutorial.

The problem starts when I start with Tutorial 2 and click on "Build mountlist". As soon as it runs, I get the following error:

ERROR: Unsupported dostype DosType = 0x50445303 QUIT failed return code 20

and I don't know what else I could do since there isn't any list of possible common issues one could find. Does it ring a bell there? Thanks.

**Note: If build mountlist is used in an emulator, it requires chipset extra is set to A600/A1200 and HD controller is set to A600/A1200/A4000 for GiggleDisk to properly detect partitions.**

Did You do this?

No, because I don't run "build mountlist" on the emulator, but on the real machine. I only used the emulator to prepare the VampireBoot.hdf file with the required system files from Workbench, and that worked fine because otherwise I wouldn't be looking at the menu where the "build mountlist" option is :-)
