Missing Operating System error

As a student I downloaded a copy of Win 7 SP1 Ultimate. I burned it onto a DVD with Roxio as a bootable file. I'm trying to install it on my first build (http://pcpartpicker.com/user/nrwilsonaz/saved/6xYwrH). I'm installing it from an external optical drive connected through USB 3.0. I do not have an internal optical drive. It recognizes the hardware. The BIOS sees my external optical as well as my HDD, I can change the order of boot discs, I can select my external optical directly through boot override. Whenever I do any of these things I get "Missing operation system".

If the Win 7 disc isn't in the external optical I get a "Insert boot disc into boot drive and press a key" (or something like that...).

I've tried the 32 bit version instead of the 64. I've tried the front panel USB and the direct to mobo USB in the back. I burned a new boot disc, being sure to select Burn as Disc (closed) instead of Burn as Tracks (open) even though the original burn was closed anyway.

I'm stumped.

  • Windows 7 operating system does not provide native support for USB 3.0. Connect/use USB 2.0 ports/devices during installation process.
  • Alternatively, if you downloaded the ISO file of Windows 7 and have a spare USB flash drive lying around, you can use software such as Rufus to create a bootable Windows7 flash drive.

I believe this is the answer. I was also going to suggest using a USB 2.0 connection.

Failing this or Warlock's USB method, you can use the PXE boot ROM of your ethernet controller to install windows over LAN: http://www.rmprepusb.com/tutorials/serva

The fact that you burned it as a "bootable file" suggests you might have burned the image to the disc incorrectly.

An ISO file is essentially a raw block image of the DVD, and is typically burned as an "image file" to the disc. I've never used Roxio, but there should be an option in there somewhere for burning disc image files, including ISO files: http://img.roxio.com/enu/pdf/creator2010/create-and-burn-iso.pdf

I did explore my version of Roxio some more and I was not burning an image disc correctly. But even following instructions got me nowhere. After one attempt my system returned a warning saying the disc didn't burn correctly and I should check my firmware. My drivers were up to date though. My assumption is that my jacked up and ancient little laptop, which may or may not be fully compatible with my new external optical and that's causing issues.

Thanks for the additional software and USB suggestions. That's the project for tomorrow.

Update: I've been using my USB 2.0 slots instead for this latest round of battle.

I retried Roxio. Converting the Win7OS .img to a .iso on my local drive. Then using the Win7 DVD/USB tool to transfer that .iso to my USB. That failed. It would get 99% and then error out: "Unable to copy file. Check the ISO and the USB." I tried two different USBs. Each time it seemed like the .img had transferred to the USB, but not the ISO. They, predictably, had the same Missing Operating System error when tried in my build. I've delved into the Roxio. There's no option for UDF only burn, there's only ISO+UDF. Could this be the thing.

I download and have been playing around with ImgBurn. There's a lot of information on how to take a folder and create a boot disc with the Build tool. But I don't have a folder, I have a .img (and a .iso). I can use the Write tool to transfer the ISO but there's no option for making it bootable. I'm just about out of blank DVDs so I don't want to try that tonight.

Rufus will be my next step. Maybe it'll work better than the Win7 USB/DVD tool. I can also try my housemate's computer for this whole ISO burning deal. Maybe it's just my super old Dell Studio XPS13. (My work machine only has DVD ROM. Meh.)

Also, my Win7 .img file is about 3GB. Is that reasonable or is that jacked? I have Win7Pro 32 and 64, and Win7Ultimate 32 and 64 and they are all about the same size, 2-3GB.

Morning Update: So.... after yet another Google search. I right clicked the .img file, selected Burn as disc image, completed that. And it's off and running in my new build.

One of those times where I just assumed it was more complex and totally bypassed the simplest of solutions. (Granted, the instructions I got with the file bypassed the simple solution too and suggested I use a 3rd party burner).
