✔ Best Answer
You have a boot loader installed (Grub4DOS).

Is there a reason that you have GRUB installed? Is your intention to boot to multiple operating systems? If not, then you need to get rid of GRUB.

Your Notebook originally came with Windows 7 home premium 64 bit. So I assume you are installing with a full DVD of Windows 7 Ult. 32 bit.

If you actually formatted a partition on your hard drive there must be another partition with GRUB installed on it.

How are you installing Windows 7? Do you have a full installation DVD? If you don't need to save a recovery partition on the hard drive then the simple approach is to use the custom install method and delete ALL partitions instead of just formatting the partition that Windows is installed on. Then create one partition using all available space. Format that partition and install Windows 7.

A Drive is a hardware device (hard drive, optical drive, floppy drive, etc), a Driver is software (video driver, sound driver, network driver, etc).

You either had Linux installed or attempted to install Linux & failed, or you deliberately installed Grub so that you could load multiple operating systems. OR you're using a pirated copy of Windows that someone doctored up. Regardless, you need to get rid of Grub & replace it with the Windows Boot loader.

This easiest way to clean up your mess would be to do as OtheHill suggested at the bottom of his response. Delete ALL partitions, create one new partition, then reinstall WIndows from scratch. You will lose all your files & programs in the process so make sure to backup everything that you want to keep before you get started.
