  1. Hello,

    I have windows 7 Laptop and I had installed Redhat 7 without using any Virualbox.

    I am facing problems selection of boot options & unable to do LVM partition due to less space available as per the system. But I have 1TB hard disk, please suggest

  2. Hello,
    I am using ‘RHEL-7.1x86_64’ iso to install on windows 7 (AMD PRO A10), using VMware workstation pro 12.
    I followed all the steps and installation got successful, but after ‘Subscription Management’ window, it shows a error as ‘Oh no! something has gone wrong, System cant recover’

    Can you guide what is going wrong here? Is it compatible to use rhel on my windows(amd) with vmware workstation 12?

  3. Have problem installing CentOS 7.1 from DVD.
    Won’t accept my root password despite I follow the requirements and recommendation for creating a strong password. I am stuck in the mud here. Have tried different variants but no one will work. How to go on?
    Thanks in foreward. OE.

    • No u can’t.
      Without Subscription you can not update rhel 7. You may like to use CentOS 7 which is a clone of RHEL 7 and don’t requires subscription.
