Can't upgrade Oracle Linux6.5 to 7
Hi,
I've install Oracle Linux 6.5 with minimal set of software,and without register ULN.
And I set up my network with DHCP and disable SELinux and turn off Firewall.
Then I try to upgrade it to Oracle Linux 7.But my OS is broke!! It won't boot up anymore.
Please help me fix this.Or it have another way to upgrade this without losing data.

This is my /etc/yum.conf config.
