It is correct.
It is correct.
To be precise: First I erased the disk and used OpenSUSE on Legacy mode, then I erased the disk and now I am using Windows 10 on UEFI mode with Security Boot Enabled. Which leads to the question “How can I create a bootable usb on Windows 10 that works with Security Boot Enabled?”
The bootable USB was created with dd.

How can I eliminate this post?
You better first compose a useful post somewhere in a document. Then read it over and correct it. Then think about it again, does it have all information needed, does it have logical steps, does it NOT assume that others will understand by magic what I want or what i did. Then go away for 10-15 minutes and do something different. Then again look at what you want to post. Only when you are really convinced that this is the best way to post, copy it into a post and send it off.
There are forums that I can delete a post 
This forum should have this feature…
Ok you want bootable USB from Windows right??
Use this program you can’t just copy the ISO you must do a binary copy to the USB device. The ISO image must replace any formatting on the USB

Then it may or may not make a difference depending on details of the hardware UEFI if secure boot is off or on but in some cases you must turn it off in the UEFI/BIOS during install
if you tick the use secure boot box during the install you can then turn it back on again after the install is completed.
IMHO Secure boot is security theater if a bad actor can modify the boot stack they already own the machine and it is too late to do anything:’(
A comment on selecting “Legacy” vs UEFI,
Although UEFI has been the standard for installs and new purchases for several years, “Legacy” was probably still “good enough” because the extra protection provided by UEFI were recognized to be needed “some time” but no actual exploit was known to exist in the wild.
That changed this past year,
A published exploit in the wild means that the potential for new exploits to attack the “Legacy” MBR disk layout has greatly increased.
So,
Although still not considered a commonly seen attack vector, anyone who doesn’t feel they can evaluate the risk should use the UEFI boot.
IMO,

Thank you for the link 
I searched about Secure Boot and honestly I think it is better to turn it off.
I can´t disable it directly on Acer’s InsydeH2O, so I will try to disable it from Windows 10 and if it is successful, then I will try to install OpenSUSE as my only OS on UEFI mode with Secure Boot Disabled.
Oh dear is this one of those machines you have to use Windows to edit the UEFI?? If so do not remove Windows. In most machines you should be able to get to the UEFI settings from the initial hardware boot screen. Consult the docs on this hardware to see what the hot key is used.
