I am having a serious issue installing Ubuntu 18.04 from a Rufus formatted USB drive. The installation goes fine expect when it gets to installing grub2 where the installation freezes and I need to perform a hard reset.
I am installing this on an HP Z2 desktop and I have installed Ubuntu on several other machines in the past and never had this issue. I have tried disabling fast boot etc in the BIOS menu and attempting to installer older versions of Ubuntu but to no avail.
I have also tried opening Ubuntu in the "try Ubuntu" mode and using the boot repair tool but this doesn't help either.
Before I had encountered this issue I was having another issue where the machine wasn't reading the USB drive and I was getting the following message "\EFI\BOOT\mmx64.efi - Not Found" but I managed to solve it here Can't install Ubuntu 18.10 on XPS 15 - EFI\BOOT\mmx64.efi not found.
The workaround that I used involved going into EFI/BOOT and making a copy of grubx64.efi and renaming it as mmx64.efi so I don't know if this is part of the problem? But the grubx64.efi file is still there and if I don't do this then I can't start the installation.
Any help that could be provided would be greatly appreciated
