Can't Install W7 Due To MBR

I want to install W7 Home Premium SP1 on a 300GB hard drive with only
one partition on it, containing a running old version of W7 I had that
is corrupted with garbage that has slowed me down horribly with stuff
I don't want. I want to start clean.

When I try to install from Installation disk, it tells me:

WINDOWS CANNOT BE INSTALLED TO THIS DISK. THE SELECTED DISK HAS AN
MBR PARTITION TABLE. ON EFI SYSTEMS, WINDOWS CAN ONLY BE INSTALLED TO
GPT DISKS.

What can I do? Should I just format the disk? I don't mind losing
the content obviously. When I installed the earlier version, I don't
recall doing anything concerning EFI or GPT, and it had been running
just fine.

Please and thank you

Big Fred

Have you tried using the advanced options during installation that
allow you to delete everything on the disk, and then make a
partition and start the installation? I'm assuming you are
installing from a CD at boot.

Normally you can format an hard disk with a MBR bootsector. Modern
motherboards use the EFI instead of the old BIOS. In your case it
obviously defaults formatting an hard disk with a GPT bootsector.
You can either format your hard disk (with the GPT bootsector) or change
the EFI settings so it will format the hard disk with a MBR boot sector.
In either case your hard disk should be formatted due to the fact you
don't need your existing data anyway.

The link below discusses a fellow with the exact question, with an answer
saying to delete all partitions and start over as you mention.

Also read this response about changing the EFI settings in the bios.

However, if you decide to get rid of the partition consider what type of
Win7 install disk you have first. If it's not the full version of Win7, but
an upgrade then the install disk will look for a previous version of Windows
before allowing the install. If there's nothing there you would need to fool
the OS install disk

I missed that. Found it when I re-tried the install and the options
cleared up my problem. Thanks
