virtualbox.org

Hello,

I recently started a new job and (one) of my work PCs is a Mac. I'm trying to get a few VMs up on it for easily testing things, however I've had no luck getting Windows 7 to install via VirtualBox. Currently my issue is that BOOTMGR cannot be found during setup, so I cannot install Win7.

I am booting/installing from a burned .ISO that I've confirmed is bootable. My optical drive is an external USB, which I've read can pose some problems. VB recognizes the optical just fine when I boot the VM but I hit a dead end after that.

Suggestions? Happy to provide additional info as needed.

No fixes?

In order to better understand the problem you need to submit some more information. Please read the following: Minimum information needed for assistance. As far as the VBox.log.zip goes, here's what you do:
- Start the VM.
- Record the error message. EXACTLY. Post a screenshot if you have to.
- Shut down the VM.
- Right-click on the VM in the VirtualBox Manager.
- Select "Show Log..."
- ZIP it and attach it in your response.

Error - CDBOOT: Couldn't find BOOTMGR.

Apologies for missing that.

Well, a quick search at the internet shows that a lot of people have this error in physical hardware as well. It usually comes from bad-burned DVDs. You mentioned that you burned this DVD from an ISO. Why don't you try to boot directly from the ISO instead? See if that solves it...
