Thanks for answer me Demm!
1.- Windows works perfectly. I ran Chkdsk but there isn't any errors on the disk
2.- I checked blkid and this is the outpost
/dev/sda1: LABEL="Reservado para el sistema" UUID="20B833CEB833A168" TYPE="ntfs" PARTUUID="89408940-01"

3.- I opened the fstab file and it shows this:
UUID=11eb187d-96fa-4c22-b9c0-4015cfc67ce8 / ext4 defaults,noatime 0 1
UUID=21542ac2-ale3-4ea7-9d22-8362a8aff6ee swap swap defaults,noatime 0 0
UUID=1E44A4A234D8A020 /home ntfs defaults,noatime 0 2
I don't know if there is a problem. Fstab shows only three partitions. I think the Windows partition is not there (sda2). But i dont know how to write there the last numbers on the fstab file.
Another clue. The laptop sounds and blink like if the system go on graphical mode but still remains on the black screen and the message i posted before. And if i just let it 5 minutes there the screen goes to sleep in inactivity mode. I use the touchpad and turns back the black screen with the message. Does this means the laptop is working and it is a graphics problem?
Edit: I read the fstab on archwiki and i think the file doesn't have any problem. Any ideas?
