Aurola Posted May 2, 2020 Share Posted May 2, 2020 Hi All, i am trying to install Catalina 15.14 on a 5570 and am successfull in reaching the installer window. i followed this guide from Jake Lo with latest clover and bootpack E7x70 because the specs are closest to the system i have. I also did the step in disk utility Boot with the USB installer, start Disk Utility and initialize your SSD as an APFS drive, name it "Catalina". But when i want to start the installation and open the installer log i get the error "Unable to get FS for volume" in the beginning and it stops with "disk is not convertible to APFS" i tried with two different ssd's and even with ons M2 disk all with the same error, does someone have an idea? regards Link to comment Share on other sites More sharing options...
Administrators Hervé Posted May 2, 2020 Administrators Share Posted May 2, 2020 When you boot the USB installer and reach the Catalina installation screen, do not initialize your disk as an APFS drive. Instead, format your target partition as HFS+ (Journaled) and ensure you've used the GUID partition scheme of course. Your drive/partition will automatically get converted to APFS volume during Catalina's installation. Link to comment Share on other sites More sharing options...
