Trouble erasing Win 8 from hp laptop

I used the feature in Win 8 to erase everything so I can load my new Win 7 disc but its still here. I'd like to get this off of here what am I missing? All the erase procedure took out were the programs I had loaded. All help appreciated. Thanks

You can't "erase" an OS from the booted OS. Boot the Win 7 install disk and do a "clean" install which will format the drive and install the OS.

It won't install, clean or otherwise. I click install from the disc file and it just does nothing, just comes back around to the same window with buttons that say check compatibility on line and install.

Windows 7 Pro X64 SP1

As Strollin posted, boot from the Windows 7 DVD. Do not launch the Windows 7 DVD from within Windows 8. If you boot from the DVD, you should be able to delete the partitions from the hard drive, wiping everything.

I'm not sure what hotkey HP uses to bring up the boot menu for their laptops, but it may be F12.

I will try that. I don't have much/any experience with this so please forgive my ignorance.

Booting means starting up a big program.

In this case that big program is windows 7.

Booting from a dvd means start the machine,usually before the manufacturer logo appears - there should be a prompt to press an f key or del or something - to get a boot menu, or boot selection, or similar.

You have to press that quite quickly.

A little window pops up listing available boot devices.

Arrow down to dvdrom or cdrom - whatever they call it on your list.

Put win 7 dvd in the drive, close it, give it a few seconds, then press eneter.

You will get another prompt - "press any key to boot from dvd"

( If you don't see that on your screen , you may need to enter bios setup )

I have entered the start-up menu and found the following;
F1 Sys info
F2 Sys Diagnostics
F9 Boot Device Options
F10 Bios Setup
F11 Sys Recovery

After pressing F9 it goes to Boot Option Menu followed by;
OS Boot Manager
Internal CD/DVD ROM Drive (UEFI)
Boot from EFI File
Notebook Harddrive
Internal CD/DVD ROM Drive

I went into CD/DVD ROM drive UEFI and it took me to a 'Windows' window and would not allow me to boot from there.
There are 5 different lines but they all say I am not allowed to boot from any of them. I'll do another restart and write them down.

I boot from EFI file, it says windows is loading files, setup starts, asks which type of install, upgrade or advanced? I choose custom from advanced. It says windows can not installed be to any of the 5 partitions. I tried Upgrade and it says to insert disc after starting Windows normally. This doesn't work either. Thanks in advance...

I would do the following - your BIOS must be in legacy mode:

1. Boot your PC with your Windows 7 installation disk and find the Command Prompt - see here how (option 1)

2. Run the following commands:

List disk
Select disk n (where n is the number that was given for your disk in List disk)
Create partition primary
Format fs=ntfs quick

3. Install Windows 7 with your installation disc into this partition.
