Hi
I have got a lot of trouble upon trying to install Ubuntu Mate on an USB stick using a Macbook Pro 2014.
I do not want to install it on its hard disk and do not want to run a live CD on USB, but a full bootable ext4 system.
I downloaded 22-04 LTS Mate and first got a live CD on USB.
From there I plugged a second USB stick and ran the install procedure from the live CD on the 1st USB.
The install procedure gave only the choice to install "along Windows (sic)" or to take over the full disk.
I had to use "something else", chosing to format the USB drive dev/sdd/, installing Linux on /dev/sdd/ and installing the grub on dev/sdd/boot/.
After the installation, the USB drive dev/sdd/ was not bootable.
The installation did install grub on my harddisk "what I absolutely wanted to avoid"
and the USB drive dev/sdd/ was created without boot flag, and without the indispensable EFI partition, so being useless.
Even grub was unconfigured, unable to start anything from USB drive dev/sdd/.
So now how can I remove grub from my harddisk?
What is the correct method to get Ubuntu Mate fully installed and bootable on an USB stick?
Thank you for your advice.
