Continuing with the previous subject that it was blocked.
Of course I want to use legitimal RouterOS I tried first with the free version so when it manages to make it walk, to buy the license. Because in the test if I can´t I format the disk I perhap I can loose the license. I think that buying the license, we contributed with the growth of which we used. All my node are legitimal Mikrotik!! And for this reason I'm doing the official training of Mikrotik. Sorry If I tried with another version, but was only to see if can I solve the problem and see what is happening!!!
Well continuing with the question of installing in a PC, I change the disk and wath say now is "Loading E" and stop. It could be an hour and will be in the same point.
