Desktop computer stuck on Intel boot screen

My desktop has Windows 7. I tried to install Windows Vista but it was giving an error 0x80070070. I tried to delete the C: drive and create a new partition.

However when I pressed the delete button it got stuck with no response even after half an hour so I decided to shut it down.

When I restarted, my PC kept on getting stuck on the Intel icon (see the picture above). I thought there could be a problem in the internal HDD as whenever I disconnected the HDD the PC would work fine, but since there is no HDD it books into Realtek name hardware.

I checked my HDD wire and cable thrice and also changed the SATA cable. I touched the HDD while the PC is running and it's moving with no apparent heat issue. The red light is continuously stable with a dimmed light.

How can I fix this?

I think you corrupted your installation of Windows so you will have to make a bootable USB or CD with another installation of Windows or another operating system such as Linux which is free.
