I'm trying to downgrade to Windows 7 32-bit for a legacy PLC computer. I created a USB disk with the proper ISO using the Windows 7 USB DVD Download Tool. Booted in, selected the drive and get "setup unable to create a new system partition". I went to advanced removed the partitions still no luck. So I took the following steps.
Backed out to the cmd prompt.
select disk 0
create partition primary size=200
format fs=ntfs label="System Reserved" quick
create partition primary
format fs=ntfs label="Windows 7" quick
Restart, try to install to Windows 7 disk, still no luck. Any other ideas?
