You downloaded the bootable media to use it for recovery. You create an empty VM and start it with the ISO image. 

You receive this error:
Unable to load initial ramdisk.

After pressing Enter, you receive this error:


The issue can be caused by one of these two reasons:

  • Malfunctioning ISO image (the download could have corrupted the file)
  • Insufficient RAM
  • badly written media (CD, flash drive)

Note that according to the following article of the User Guide, the Bootable media or a disk recovery with a reboot requires at least 1 GB of memory.


  1. Check if the RAM is sufficient for the target machine. In case it is not, adjust the hardware. 
  2. Try to download the media ISO from another machine/network and retry booting up. 
  3. Try to rewrite media.
