I installed ubuntu on a macbook pro 2008 and now it only boots into the grub command line. I want to install kali linux on the machine but first I need to get it to boot for the usb. Code: grub> ls (hd0) (hd0,msdos1) (hd1) (hd1,gpt3) (hd1,gpt2) (hd1,gpt1) (cd0) grub> set root=(hd0,msdos1) grub> chainloader +1 error: invalid EFI file path grub> chainloader /[tab] possible files are: / / .disk/ autorun.inf dists/ firmware/ g2ldr g2ldr.mbr install/ isolinux/ live/ md5sum.txt pool/ setup.exe tools/ win32-loader.ini ^^ this what I have tried to no success. Any help? When I try to enter the EFI "bios" for the mac I just get a white screen with a mouse which I can move around but thats it. If you need more I will give you all that you need.
