I just downloaded and tried to add new virtual machine, but it gives me an error. I couldn't find the solution. it seems that VM can not find the OS. I don't know how to resolve.
Error is:
FATAL: No bootable medium found! System Halted.
I have Vista and latest version of Sun VirtualBox.
This is now working fine. The virtual machine should point to the .iso image of the OS. This can be done by following steps:
In the Virtual Machine window (where this error is appearing), go to "Devices" tab --> CD/DVD Devices --> More CD/DVD images --> select the location where the .iso image for this OS is stored.
Now Power off the machine and again start from the Virtual box. Your Machine should start.
Hi the Answer is simple.
Go to settings > Storage > Storage Tree
and mount your image/CD/DVD drive under Controller: IDE (Don't use SATA)
Either add a new CD/DVD device or use the existing one.
The reason that VirtualBox can't find the OS is that there is no OS.
In order to boot a virtual machine to an OS, you have to install an OS first by mounting an ISO or physical CD with a bootable OS install (eg, an Windows or Linux installation disc)
When you first create a Virtual Machine with VirtualBox, there is no OS installed on the HD image. You have to have the VM mount a bootable ISO image to install the OS from.
In my instance, I needed to have two .iso images attached as optical devices during an install. I found that after adding the second image to the IDE controller, VirtualBox ceased to recognize the first image as bootable.
After much trial and error, I was able to boot once again by choosing Settings > Storage, selecting the bootable .iso image and changing its attributes to IDE Primary Slave.
For what it's worth, I also had to change the attributes of the other .iso image device to IDE Secondary before the Primary Slave option was available for the bootable image. I imagine the order in which you add the images to the storage tree may determine which attributes are assigned to them.
Try this:
Solution: Try a different architecture type of iso.
I was able to solve this problem by changing the ISO image. I was trying to install cent os 7 with virtual box on mac 10.11.6 (el-capitan ). First I had downloaded the minimal set up from here: https://wiki.centos.org/Download
There are setups available for different architecture types. I first tried with aarch64. But could not get past the same error: Fatal: no bootable medium found! System Halted
Tried everything but never solved. Then I tried "i386" . And it worked.
New MacOS Operative System are not ready out of the box.
My solution was to get rid of the Catalina.iso, then:
High Sierra.appHigh Sierra.dmgHigh Sierra.iso
Newer OS like Mojave or Catalina are not ready yet, they will probably be ready in a few months/year. This is the price to pay for free software.
I was installing Windows XP via VirtualBox using the "Windows XP Mode" official release from Microsoft, which gives you a VirtualXP.vhd virtual hard disk file.
In the setup wizard, the default choice is:
Create a virtual hard disk now
I selected this and created a virtual hard disk. I thought I had already selected and used the downloaded file on the first page of the wizard.
But you'll get the FATAL: No bootable medium found! System Halted. error when you run the VM.
Instead, in the situation where you are booting off a provided .vhd rather than a .iso, you should select:
Use an existing virtual hard disk file
and click the folder icon to select the .vhd file you are trying to load.
Now your downloaded .vhd is the "bootable medium", and VirtualBox won't be looking for a .iso or CD drive to load.
If you added the iso file but its still not working, then if there is a file named "empyt", make sure to remove that attachment.
