current latest download of LinuxCNC V2.9.8 will not install GRUB on several PC's

I downloaded the 2.9.8 latest version from the first link in the download page
Burned this iso to a pen drive under windows using Rufus latest version
Live preview works fine
Graphic install consistently fails at the point of installing GRUB

 
 

It's a bit hazy in my memory what I did the ocational time I ran into that. I recall fixing it by choosing a different partitioning scheme during installation.

edit:
One day it was simply not working (grub install failed) and I finally started over with a different pen drive then it just worked. My pen drive was not quite up to snuff. Also confirm your downloaded iso contains no errors.

Thanks for the reply NWE
I’ve downloaded the iso 5 or 6 times and burned it to many different pen drives using various versions of Rufus and bletcher (I think that’s what called)
My friend also downloaded the same iso and burned it to a pen and installed onto a NUC without issue. He lent me the pen and that one failed at the same point
Also tried on numerous PC’s and numerous hard drives both ssd and mechanical hdd

I’ll give your theory on partitions a try tomorrow
Thanks

Not wanting to derail the original topic but my work around of installing 2.9.7 and then using the package manager to update to 2.9.8 failed

2.9.7 install from the iso ok other than a slight problem with a profile error on the desktop package. This did not affect anything
connected WiFi ok
apt package manager reported broken packages that needed fixing before linuxcnc would update to 2.9.8
fix broken packages didn’t work
so I’m some what stuck with my workaround

Can’t find anything in the bios related to csm

Not all bios seem to have that.

If bios has CSM and it is turned off, I have no luck booting anything in legacy bios mode, I get:
"No boot media found"

My hazy memory is slowly refreshing. It seems I manually created a small bios boot partition (legacy mode) or efi partition (uefi mode). I never investigated why I had to do that; whether:
1. The automatic partitioner failed to create it, or
2. Some option I had selected prevented it from creating it automatically.

Posting a screenshot of what it is creating at the stage it asks you to confirm the partitioning might be helpful. I'm not sure whether there is an easy way to take a real screenshot of that, you might have to snap a photo of it.

I didn’t spot it in the bios but equally wasn’t looking for it. Is it normally in the same area of the bios screen that legacy mode and secure boot reside ?

 

That sounds like it... Trusted computing. Boot priority. Those are some areas I'd think of checking. If it is nowhere, then it probably does not have CSM.

One naughty bios in one of my systems a while back showed: CSM = disabled. It could not be enabled. The manual said it can be enabled if you install a graphics card. I tried that and it worked. Which was a problem because it had only one PCIe slot and I wanted something else in it; I had no need for a graphics card on that system.
