cannot reinstall windows 7 home premium

[rambostyrer]

Needed to reinstall my windows 7, and got so far as to format my harddrive partitions through my windows dvd.

but I cannot install windows on my old system drive.

When i enter the menu to choose my windows drive, the next button is blanked out, and the installer tells me it is a GPT partition - and I have no idea what means.

I have tried to re-format but that does not help either.

please help me solve this

That means you have formatted the drive as a GPT (rather than MBR) drive. If it is a drive of 2TB or less, I would boot from the installer disk and select command prompt. Then type:
diskpart
list disk
select disk n (where n is your target disk to erase -- do not get this wrong)
clean

Then restart with the installer disk in to re-install Windows.

thanks that did it.

It is one of the choices when you boot from the installer disk. If it is stuck powered on, just unplug it -- won't hurt anything.
