Uploading ISO under 2GB to iDrac8

Posted on Saturday, September 26, 2026


 

I have a Dell R730xd server with an iDrac8 and a 16GB vFlash.   Here is how you can upload an iso that is under 2GB to it to use for installing an OS on the drive

Why do I say under 2GB?  Well if you are going to use the iDrac html5 web interface you are limited to a max of 2GB for upload.  There are other ways to upload a bigger ISO but that is for another article.



Let’s go pull Ubuntu 22.04 ISO (This ISO is under 2GB… 24.04 and 26.04 are over 2GB so we can’t use them for this method)

Download it from https://releases.ubuntu.com/22.04.5/ubuntu-22.04.5-live-server-amd64.iso
I just ran a simple wget to pull it down

 

  > wget https://releases.ubuntu.com/22.04.5/ubuntu-22.04.5-live-server-amd64.iso

 


Select OverviewàServer then click on VFlash


 


Select Create from Image tab


 

Here you will see the Note that says you are limited to 2GB

 


For the label I am setting it to UBU22
For Emulation Type set it to CD.
Then click on Choose File in the Image location field.

 


 

Select the Ubuntu 22.04 ISO and click Open.

 


Click Apply

 



Now watch it upload.  It will take some time.  In my case it took ~ 30 minutes.

 

 

 

Installing from an ISO on the vFlash

To now use this ISO on the vFlash to install do the following.

 


From the vFlash tool.  Select manage then checkbox attached for the ISO you want to install and click Apply.

Now Launch the Virtual Console

 


From the Virtual Console click on Launch Virtual Console

 



Now power cycle the box.

 

Watch it reboot in the virtual console.

 

Press F10



 

 



Now it will enter the lifecycle controller in a minute as it boots up.

 

 

 

 



Click on System Setup then Click on Advanced Hardware Configuration.

 

 


Click System BIOS

 

 


Click Boot Settings

 

 


Click UEFI Boot Settings

 

 

 


Click on UEFI Boot Sequence

 

 

 


Select our ISO that we mounted as a CD and click the + button until its at the top.

 

 


Click OK

 

 


Click Exit

 

 


Save the Changes

 



Click OK

 

 


Click Finish

 

 


Click Yes.

 

 

 

 


Now it will start up and start from the ISO so you can install the OS.

 

 

 


OK now we are at the install menu!

 

I am not going to walk through an Ubuntu 22.04 install but this covered how to get there from an ISO on your iDrac 😊
