I was trying to install windows 10 on my MacBook Pro 2012, I was following apple tutorial (https://support.apple.com/pt-pt/guide/bootcamp-assistant/bcmp09f5f773/mac)(or in English). I chose 100GB to windows partition. Everything was going great until I came across "no bootable device insert boot disk and press any key" message.
I went back in MacOS to remove the Bootcamp partition to repeat the process again, but I couldn't find it.
Here are some prints from disk utility:
what can I do to undo and resize the original MacOS partition to try to do the bootcamp again?
Thank you in advance and have a great weekend!

If you are still failing to install Windows though the use of the Boot Camp Assistant, then consider using the following steps to install Windows.
