I am on the method 4 trying to install windows 10 directly from hard disk of imac and when I press LIST DISK it shows:
Disk 0 online 113 GB

Disk 1 online 931 GB
Therefore, I don't know which I must choose disk 0 or disk 1.
My imac has only 1 TB and on the disk utility shows:
APPLE SSD MEDIA 121.33 GB Disk identifier disk0
CUSTOMER 120.99 GB Disk identifier disk0s2
APPLE HDD 1 TB Disk identifier disk 1
BOOT CAMP 70.72 GB Disk identifier disk 1s4
Any suggestions? Cheers

From the outputs you have posted it looks like your system has hybrid configuration of 113 GB SSD and 1 TB HDD.
I would suggest to first take a backup of any useful data present on the 113 GB SSD and then erase the SSD and continue with the steps for copying installation files on it.
