These instructions are based on this blogpost by Anton Semjonov and this video by Animortis Productions. Please follow the link if you want more details, they go into much more detail about each step, whereas this document is more focused on being a concise cheat sheet. Let's go.
Boot the Ubuntu installation medium. When asked, choose the "Try Ubuntu" option and open a terminal.
Switch to root, otherwise you'll have to type sudo all the time:
sudo su -
Shell function one-liner to produce a pseudorandom hostname in the style of Windows 7, Windows 8 and Windows 10 e.g. DESKTOP-V1XZZQ3
random_windows_hostname() {
printf "DESKTOP-$(/usr/bin/tr -dc A-Z0-9 </dev/urandom | /usr/bin/head -c 7)"
}
echo "$(random_windows_hostname)" # produces DESKTOP-V1XZZQ3
| ### Preseed for Ubuntu 18.04 | |
| # Derived from: https://help.ubuntu.com/lts/installation-guide/example-preseed.txt | |
| ### Usage | |
| # We recommend to use the build-iso.sh script to build an image with embedded | |
| # preseed and other required files. In that case the preseed file gets loaded | |
| # automatically and all additional files are available to the installer. | |
| ### Unattended Installation | |

Unlike using VMWare Tools to enable Linux guest capabilities, the open-vm-tools package doesn't auto-mount shared VMWare folders. This can be frustrating in various ways, but there's an easy fix.
Install open-vm-tools and run:
sudo mount -t fuse.vmhgfs-fuse .host:/ /mnt/hgfs -o allow_other
# stop active raid
mdadm --stop /dev/md[01]
# destroy partition table on hdds
dd if=/dev/zero of=/dev/sda bs=1M count=512
dd if=/dev/zero of=/dev/sdb bs=1M count=512
dd if=/dev/zero of=/dev/sdc bs=1M count=512
dd if=/dev/zero of=/dev/sdd bs=1M count=512
Setup One: Buy a Mac if you don't have one.
Setup Two: Install Homebrew
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
Setup Three:
# stop active raid
mdadm --stop /dev/md[01]
# destroy partition table on hdds
dd if=/dev/zero of=/dev/sda bs=1M count=512
dd if=/dev/zero of=/dev/sdb bs=1M count=512
# create new partition table
sgdisk -og /dev/sda
