No Operating System Found

[Snowman1978]

Hello, 

I have a Elite Desk 800 G1 SFF ,

When I go to Start Up it says No Operating System Found, Press Control, Alt, Delete to Restart. 

I tried to Use Control F11 to Get Into HP Recovery but it only stays in that screen for a second and goes back to No Operating System Found, 

I can get into BIOS, (Not An Expert) But I tried to move the Hardrive Up in the Boot Order but still no luck, I then just reset the BIOS to Default Settings. (I am assuming Hard drive is okay because it can read its a 1TB one) 

It Says Windows 7 Pro on the Case, but I don't remember if it was upgraded to a newer version.

I was going to try a "clean Install" but Windows wouldn't let me download a ISO because HP has the rights to my window code? (That seems really stupid) 

Is there anyway I can salvage this computer? or is it just garbage? Seems like a waste to throw out I-5, Ram and the Hardrive. 

Another Thing, There is a Video Card installed, I removed it to see if it would boot but still had issues, when I plugged the card back in it wasn't working anymore, so I am using onboard Blue Connector with the screen now...

Thanks,

Hi:

If it has W7 Pro you I have posted the link to the W7 Pro 64 bit ISO file below.

https://download.microsoft.com/download/0/6/3/06365375-C346-4D65-87C7-EE41F55F736B/7601.24214.180801...

The link will be good for 24 hours from the time of this reply.

You can use the Microsoft tool that I zipped up and attached below that you will need to transfer the ISO file to a DVD or USB flash drive so that it is bootable.

Thank you for the Software,

I Downloaded it, Used the Tool to Put it onto a USB

(There was an error saying it was unable to run bootsect to make usb bootable)

(Is this an Issue, Google Search said that it just means USB is already Bootable?)

I plugged it into the HP Computer, went to boot menu, booted from USB, I forgot what it said but something like:

Attempting to Boot,

No Operating System Found, 

Is this something to do with the Bootsect? 

Thanks,

You're very welcome.

I would try a different utility to make the ISO file bootable.

Rufus is usually a good option.

If you have a PC with a DVD burner and a writable DVD, you can also use this free DVD burning software to burn the ISO file to a DVD so that it is bootable.

Select the more download options, and select the default installer without installcore.

Open the program and select the Burn ISO file option.

Burn the file at the slowest speed you can to get a good burn,
