How to ‘FSL: \ system/library/coreservices \ boot EFI’ is not recognized as an internal or external command, operable program, or script file?
I don’t know the macOS 10.15 Catalina boot is the most problematic OS ever tested on VirtualBox on Windows PC. The Error for AMD system, the screen resolution problem or not getting into the boot. However, the ‘FSL: \ system/library/coreservices \ boot EFI’ is not recognized as an internal or external command, operable program, or script file, is another error.
To fix this Error while installing macOS 10.15 Catalina on VirtualBox on Windows PC, simply Install.nsh.
In case the install.nsh did not work, you have to turn off the running virtual Machine on the VirtualBox, then change the VirtualBox Chipset to PIIX3. You can change it from the system tab on the setting.
However, if you face any of the below errors, I do not have any idea How to Fix them, but if anyone of you found the solution, please let me know. In the middle of there are some Questions which contains the answers too.
Q1: I have repeated the entire process, the chipset was already set to PIIX3. The error persists, unfortunately.
Q2: Hello, when I type install.nsh it just answers “fs1:\macOS Install Data\Locked Files\Boot Files\boot.efi” and nothing happens after that.
Q3: Hi, In the virtual box “install.nsh” section it stops loading the prompt screen and says “apfs_module_Stop… Creating RAM disk for /var/tmp/recoveryTemp, Have I run out of RAM or can you help me with this.
Q4: After running install.nsh on the VM, It does not go to an install screen, but instead runs lines of code in the UEFI window. I see many lines saying failed to open/locate/mount but it keeps progressing until it gets to “creating RAM Disk” lines and then just stops.
When running install.nsh is it supposed to popup the macOS install screen? I followed directions exactly, even deleted the VM and repeated several times with the same problem. Any ideas?
Answer: change VirtualBox Chipset to PIIX3
Q5: I have followed the same steps exactly, but after the system booted up, I got an error message”:
The device helper structure version has changed.
If you have upgraded VirtualBox recently, please make sure you have terminated all VMs and upgraded any extension packs. If this error persists, try re-installing VirtualBox.
