  6. (Optional) Click settings (Settings) at the bottom of the VM to adjust the CPUs, RAM, and virtual disks on the VM Hardware Settings page. Make sure the VM has enough resources to support the operating system.

Upload the ISO image to Skytap

Upload the ISO to your Skytap Assets page. This allows you to later mount the ISO in the VM CD/DVD drive.

For instructions, see Uploading files to the Assets page.

Upload the ISO to the same region as the VM.

    2. Click load iso (Load ISO) at the bottom of the VM.

    3. Assets appear as a pop-up window; select the appropriate ISO asset and click load iso (Load ISO) (see Using ISO files for an illustration of this process).
  2. Use the Boot Menu inside the VM to boot the VM from the CD-ROM Drive:

    This temporarily changes the boot order for the VM so that it starts from the CD-ROM drive. If you restart the VM, it will revert to its normal boot order.

    1. Click on the thumbnail image of the VM desktop to open the Secure Remote Access (SRA) browser client


      There is no OS loaded yet, so the VM won’t boot.

    2. Click Ctrl-Alt-Del in the browser client toolbar to reboot the VM.


    3. When the VM starts to reboot, and while the VMware startup screen is displayed, press Esc on your local keyboard to enter the Boot Menu.
