SSD problem when booting

Dear friends,

After installing MacOS Catalina on my Macbook I had problems starting Bootcamp with Windows. I decided to erase the partition but in the moment I tried to create 2 partition i couldnt start my Mac anymore. During the boot and the Apple logo i receive a message in more languages that the Mac cannot start because of a problem.

Actually I connected my SSD to another Mac and:

Some programs like Disk Drill can see the SSD and the partition in there with all the files.
Utility disk see the SSD but don´t let me do any action and Disk Warrior cannot see the SSD

Any help would be appreaciate.

Thank you,

Daniel

You cannot have but two partitions with Boot Camp - macOS and Windows. Trying to add another partition will break the boot loader. Your only solution at this point is to reformat the drive as a single macOS volume and reinstall macOS.

If you really do have an Early-2011 MBP, then you cannot install Mojave or Catalina. According to Apple the last supported version of macOS is High Sierra - 10.13.6. Before you progress farther, you need to clarify what Mac model you have. To find the model's complete information, select About This Mac from the Apple menu.
