Running Windows ISO from PXE. Getting error



  • Running Windows ISO from PXE. Getting error - '[FONT=Helvetica Neue][COLOR=#333333]ramdisk device creation failed due to insufficient memory". I bumped up the VM machine and my FOG server [/COLOR][/FONT][FONT=Helvetica Neue][COLOR=#333333]to 6gb[/COLOR][/FONT][FONT=Helvetica Neue][COLOR=#333333]. Which should be enough RAM for RAMDISK considering the ISO is approx 3.3gb and then for any overhead.[/COLOR][/FONT]

    [FONT=Helvetica Neue][COLOR=#333333]Is it possible to boot the ISO successfully in this manner, i.e. is it possible to boot Windows ISO’s from FOG or are there limitations on what can be booted from PXE?[/COLOR][/FONT]



  • Thanks, I am going to Try a Wn7x86 ISO to see if that makes a difference. Regarding MOD of the ISO, what is the approach I should use in the default file for a network share? We have a N5200X NAS server and I can setup a ISO share from there. Do you have an example of a default file entry to allow share from a NAS?



  • The RAMDISK is created on the client machines, not on the server. So the clients will need over 3 GB of RAM in order to load the disk. Then after the disk is loaded, that amount of RAM is unusable by the OS. Also i’m not sure what BIOS limitations there are on how much RAM the computer can use and if it is stuck in a 32 bit address space with PAE disabled until an OS boots, so only iso’s under 3 GB would load(Just my guess). Do ISO’s under 3 GB (stock Windows 7 SP1 should be 2.4 GB) work?

    Perhaps you could modify the iso so it gets it’s Windows sources from a network share, so it only needs to memdisk a smaller installer ISO.
