Hi all,

I did try to install Slackware64 14.2 in VMware workstation 12 in uefi mode using an iso image. But it fails to boot from the iso image.

However, on my old workstation using the same iso image I can install it in uefi mode in VMware workstation 10.0.2.

After copying the complete installed Slackware to my new workstation it does start in VMware 12 without problem. But I wonder why it can't boot from the iso image while version 10 has no problems with it.

Is this a VMware thing or do I need to look at the EFI folder on the iso image?

Have you tried changing the setting from "bios" to "efi" in the advanced settings? Or, you could just add:

firmware = "efi"

...to the vmx file.

In VMware 10 you can't change it in the advanced settings so I did change in in the vmx file by adding firmware = "efi".

In 12 I tried both, the advanced setting and the direct method in the vmx file. No problem installing Slackware in bios mode but it won't start the installation in uefi mode.

Which is having the issue with Workstation 12... the ISO or the system.vmdk?

If it's the ISO, you may have to rebuild it without el-torito support.

Don't think it is the ISO image. Used the same ISO in VMware 10 and 12. In 10 it will boot and let me install in UEFI mode in 12 it constantly comes with "unsuccessful" when trying to boot from the ISO.

And because of that, can't start the installation. But the strange thing is, when I copy the virtual machine (from the old workstation to my new one) it runs without problem in 12. But of course, that is a complete finished install of Slackware 14.2. It still doesn't boot from the ISO.

Are you by chance trying to boot (the ISO) on 12 from a template created on 10?

Other than that, I just installed slackware64-14.2 on workstation 12.5.7 build-5813279 from the dvd ISO. That went through without an issue, but the elilo setup crashed during the install and I'm not going to diagnose that. If I planned to use the system I'd just install slackware, chroot from debian livecd and build and install grub2 on the slackware system from the source package. (Grub2 is far easier to deal with from source than any other usable bootloader at this point.)

While you can enable efi in the vm, I'd wonder if it is actually booting into a uefi mode. Also I'd wonder if some advancement in the VM makes the client take on more of the host hardware.

The edit to efi is supposed to be usable for a number of the versions of vmware.

I guess it could be that you have boot options in some uefi computers. Some boot media may say uefi cd/dvd or such and a second choice for cd/dvd.+
