There isn't enough information. At the grub menu try removing 'rhgb quiet' from the linux boot parameters, and replacing with 'nomodeset' and see if you can at least see some text. If not then the next step is you need to figure out how to access the console from your VM. If you were using qemu-kvm this is done via 'virsh console <vmname>' so it should be simple in VMWare to figure out. What's not as obvious is you need additional changes to the grub menu entry's linux boot parameters line: rd.debug systemd.log_level=debug systemd.log_target=console console=ttyS0,38400 So you can type that into grub, and then connect to console first, then F10 in grub to boot. You want to try to connect before booting so that the console captures from the start of booting.
