RHEL in Virtual Box

I am trying to install rhel-server-7.0-x86_64-dvd.iso(RHEL7) in VirtualBox-4.3.26-98988-Win version.
But installation doesn't start itself. What i am doing wrong?

Pc config
CPU: Intel Core i5 2.5Ghz, 4GB Ram
OS: Windows 7 Professional 32 Bit

You can install 64bit guests on a 32bit OS, that is not a problem IF you comply with all requirements put up by Virtualbox.

So if your processor supports 64bit you should be able to install a 64bit OS, but you might have to change some settings in BIOS that allows this.

I see you have a 32bit OS and want to install a 64bit guest in Virtualbox, did you check if you comply to all the necessary prerequisites put up by Virtualbox?

3.1.2. 64-bit guests

VirtualBox supports 64-bit guest operating systems, even on 32-bit host operating systems,[11] provided that the following conditions are met:

- You need a 64-bit processor with hardware virtualization support (see Section 10.3, “Hardware vs. software virtualization”).

- You must enable hardware virtualization for the particular VM for which you want 64-bit support; software virtualization is not supported for 64-bit VMs.

 - If you want to use 64-bit guest support on a 32-bit host operating system, you must also select a 64-bit operating system for the particular VM. Since supporting 64 bits on 32-bit hosts incurs additional overhead, VirtualBox only enables this support upon explicit request.

- On 64-bit hosts (which typically come with hardware virtualization support), 64-bit guest operating systems are always supported regardless of settings, so you can simply install a 64-bit operating system in the guest.

On any host, you should enable the I/O APIC for virtual machines that you intend to use in 64-bit mode. This is especially true for 64-bit Windows VMs. See Section 3.3.2, “"Advanced" tab”. In addition, for 64-bit Windows guests, you should make sure that the VM uses the Intel networking device, since there is no 64-bit driver support for the AMD PCNet card; see Section 6.1, “Virtual networking hardware”.

If you use the "Create VM" wizard of the VirtualBox graphical user interface (see Section 1.7, “Creating your first virtual machine”), VirtualBox will automatically use the correct settings for each selected 64-bit operating system type.

I got confused now will i able to install or not in current scenario, because i can't change OS to 64 bit very soon.

When you state it does not start?

Does it not boot from the ISO ?

After enabling virtualization in BIOS in cpu settings, and in Virtual Box while in creating new virtual machine is selected Linux 64 bit in version option.
