No operating system found when booting from USB

1

I have a Dell Inspiron N4010 laptop running Phoenix BIOS. I downloaded the Windows 7 x64 ISO to create a bootable USB. I did this under OS X by following the instructions from this website: http://blog.lewan.com/2012/02/10/making-a-bootable-usb-stick-on-an-apple-mac-os-x-from-an-iso/

I downloaded the ISO from here: http://mirror.corenoc.de/digitalrivercontent.net/

I changed the boot settings on the Dell to make the USB the first to boot, but I get the no operating system found. The USB is UDF formated. The reason I did this on a mac is because I don't have the Windows recovery CD and I can't boot into Windows.

if you hit F12 just after POST, but before boot, does your USB volume appear in the boot list? – Frank Thomas – 2015-06-25T16:22:52.450

Are you booting in compatability/legacy mode? Did you make a EFI installation media? – Ramhound – 2015-06-25T16:23:43.073

Yes, I get USB storage and Removable Disk. I tried both but I get no operating system found. @Ramhound I do not see any option in the BIOS about legacy/compatability mode not sure what you mean by EFI media. – user420321 – 2015-06-25T16:26:40.377

@user420321 - Look it up. If you are booting in non-legacy mode then the media has to have EFI drivers on it otherwise you are required to use legacy mode. – Ramhound – 2015-06-25T16:28:51.077

1@user420321 As you have resolved the problem, I suggest that you answer your own question. After a short while, you should be able to mark it as the answer. – Andrew Morton – 2015-06-26T18:45:37.183

I was able to create a bootable Win 7 recovery USB by loading a Windows 7 ISO in VirtualBox on OS X
