installing linuxCNC 2.7.14 under Hyper-V Manager

Installation step failed
An installation step failed.  You can try to run the failing item again from the menu, or skip it and choose something else.  The failing step is: install the system.

Anyone else see this and found a solution?

latency does not matter for simulation

TBH this is not really an Linuxcnc issue but a Hyper-V Debian issue as the standard Debian installer is used.
What you can try is to install Debian bookworm from a Debian ISO with XFCE desktop then follow the instructions in the Linuxcnc docs to install the Linuxcnc packages. This is about the best suggestion I can come up with.
Personally I use VirtualBox, as it's basically flawless.

I am now trying to install under VirtualBox. It never completes. End of log:

I'll have a look tomorrow, what ISO are you using, exact filename will make life easier, any particular reason for 2.7.14 ?
Windows or Linux host ?

Host System Linux Mint 22.2 Xia
VirtualBox 7.18
Guest
32 Bit System 4GB Ram 16GB HDD
Bridged Network

Install went fine about 5 or 10 miuntes, boots fine.
Obviously Wheezy is EOL so upgrades maybe a bit funky
Linuxcnc upgrade were fine
Installation of Midnight Commander & Geany went fine
Axis sim run as expected
Shutdown was clean

Langdons, before commenting please try to read the other posts.
VirtualBox was suggested
The last error log was from VirtualBox
This behaviour only frustrates people.

Exported the VM as an appliance
