Windows 7: "Setup was unable to creat a new system partition"

"Setup was unable to creat a new system partition"

I've done a lot of googling on this and I am still getting this error after hours of trying.

I'm trying to install Win 7 on an Acer Aspire One netbook after removing Win XP from it.
After much research this is the latest command line I used and it did not work.
Any help is appreciated.

LIST DISK
SELECT DISK 0
CLEAN
CONVERT MBR
CREATE PARTITION PRIMARY
FORMAT FS=NTFS

Do you have a UEFI BIOS? If so then you need to boot the installation media as a UEFI device and a flash stick installer needs special formatting using Option One in UEFI Bootable USB Flash Drive - Create in Windows.

Delete all partitions so that that the installer can change the partition formatting if needed to GPT for UEFI, or MBR for Legacy if the PC is not UEFI.

Otherwise work through the steps to Troubleshoot Windows 7 Installation Failures - Windows 7 Help Forums

Follow Greg`s advice or enable Legacy boot in the bios and disable UEFI.

You simply disable UEFI.
