Erasing primary disk for linux installation

Installing Fedora 28

Does no one know how to spell google or duckduckgo anymore?

Searching for "How to erase disk for linux installation?" yields pages and pages of information.
Suggest you try that instead of asking us to read things to you.

The answers are to complex and varied.How about giving a hand- trying to uninstall suse and install fedora 28.

First decide if you want to keep Windows on the computer. If so, defrag the Windows partition and shrink it.

For Linux, you need three partitions:
/ (aka root)
/home (for your personal files)
swap

Use the live session of Fedora to create your partitions, using the program gparted.

Read the Fedora documentation.
http://docs.fedoraproject.org/
This is important. The Fedora installer is not simple and you need to know what it's going to ask you and what to reply. Don't opt for automatic partitioning or it will destroy your nice arrangement and, what's worse, set up Logical Volumes, which belong on a server, not a PC. You'll need the manual option, where you tell it which partitions to use for the three functions. Make a note on paper when you read the documentation. Then run the installer.

Finally add the things it doesn't have because they are patented in the USA.

Done!

Searching for "install fedora 28" gives this as the first entry.

That's a pretty step-by-step tutorial.

You don't need to uninstall Suse. When you get to the partitioning option during the Fedora installation, just choose the partition Suse's on as / for Fedora.

I never get to see installation menu

The problem is that I have SUSE installed on the drive and it only allows me to go to grub and not the installation DVD iso. Any suggestions? Thanks
Is there any way to get around grub? The situation is that SBA,SBB,and SBC are all open in SUSE and I cannot use gparted to clear any because they are open. I have gparted installed n the SUSE image.

You go to the BIOS before you get the Suse menu and change the boot option to boot from DVD if you are using a DVD or to the usb if you are using a usb drive. Do you have either available? How to do that varies with manufacturer but you should see a line before Suse boots telling you which key to use to enter BIOS or change boot options.

I cannot see how to change the grub option- it always boots to grub from SUSE- do you know of anything to bypass grub. When I boot up the machine the DVD reads but instantly goes to grub

Stop blowing kisses...it's embarrassing.
How did you manage to install Suse? By choosing to boot from the DVD in the BIOS? That's the usual way to start. Is Suse preventing you from doing that? I've never come across anything like that.
You could use a gparted live cd to delete all present partitions and start afresh.

If you're seeing grub, then you're not booting to the DVD.

You will need to do what yancek said: Go into the BIOS and change the boot sequence to boot to the DVD first.
How to do that (go into the BIOS) is (as they said) different depending on the hardware manufacturer, so you'll need to research that.
Note: It's not "change the grub option" -- it's "change the boot option"

On the other hand, it's possible that the DVD is not bootable. Where did you get the DVD?

Exactly, I cannot bypass the grub request!!! I even just restarted and let SUSE install but it would not let me get around grub in any way!
