Can I use that to install Win7 on a computer without a dvd drive?

That'll let you put it on a flash drive and install from there.

The site's not loading for me, but I saw it on lifehacker.

I guess if that website doesn't work you can download it here: http://www.softpedia.com/get/System/System...inToFlash.shtml

I am going to buy a DVD drive for that computer anyway so I want buy one that can be used to install OS's.

Thanks for your help, Red.

The site doesn't load, but i'll assume it's an external drive. Meaning it probably connects via USB, and only very modern motherboards support booting via USB. You can get a decent CDRW/DVDR for £10, which should be able to connect to even the older motherboards.

The computer is a Dell Studio 14z which is one of their newest mid-end laptops.

Hmm, so it has an eSATA port? Can you even get eSATA Optical Drives?

Since it is new then i would go with Red's idea of booting from the USB stick.

It has eSATA-USB and normal USB. I need to buy a dvd drive anyway so I want one that can be used to install win7 as it os easier than the USB method. The dvd drive on the site is a Retail Plus 8x DVD drive.

You mean a USB - eSATA adapter?

These is what my laptop has:

(2) USB 2.0 compliant ports
(1) USB 2.0 compliant / e-SATA port with Power share

Here is another site with the USB media drive I'm planning on buying:
