@bricktop135 At which stage do you get the cursor on the black screen? Can take a series of pictures or video so we see the whole boot process?

Thank you guys! It seems to be that GPT Problem. After doing the fixparts command and deleting the GPT entries now I can upload the machine :-) Hopefully deploying them will work in the usual way ;-) THANK YOU!

@jonathanh Excellent. Glad to help! Marking this issue resolved (or not, no option to…)
