fog iso booting
-
I was trying to boot linux iso using memdisk . but it is not working . i need to boot linux and windows in the for boot menu for clean installing.can any help me with configuration . can it be done in GUI.
-
@badhonsoam Need more information to be able to help. Version of FOG, what ISOs exactly - windows/linux/distro/version, config and command used, exact error messages and best if you can post pictures of the error on screen…
-
Thx.@Sebastian-Roth for your reply. I have done fog in ubuntu server 16.04. the basic function is working fine. now i want to use it as a pxe server. Through this pxe server i can install window 7,10 and linux centos, ubuntu etc. first , i make folder in /tftpboot named fog. in this i downloaded an iso.
and copy memdisk file from /tftpboot . in default section i make new level. but its not working. there is no error log. i think there is a procedure i am missing. please help with that. -
@badhonsoam said:
in default section i make new level.
What exactly do you mean by that? To me this sounds as if you’re still using pxelinux while never versions of FOG use iPXE. Please tell us what version of FOG you use, see in the blue cloud on the web interface.
-
@sebastian-roth i am using fog latest version. can you tell me how do i use ipxe.
-
@badhonsoam What, exactly, version of FOG are you using? Latest means many different things especially in us Developer’s eyes.
-
@sebastian-roth is ipxe can boot both windows and linux. i am using 1.4.4
-
@tom-elliott using fog 1.4.4

@badhonsoam iPXE can boot Windows ISO or Linux ISO, but in the case of any ISO, your system booting the ISO must have at least the amount of RAM as the size of the ISO (plus extra).
In many cases, the ISO isn’t designed to be booted directly from ISO without it being on a CD Drive too in the case of Linux. There are many tutorials around that help with this.
Here’s a few links.

I have just close my post for similar issue. however in my case I want to actually boot clients using FOG boot services for dban ISO
which WiKi says is possible. I could not make it work as described in WiKi but I use this
post to make it boot as if ISO was a real CD. that is what you want to do a install of OS, right?this definitely works.
the basic steps (and please read the linked thread fully) are#1. create a directory in “/var/www/html/” to hold the ISOs [NOTE] : the final location depends on your server OS. since I use Debian 9 I have the “/var/www/html/” check to make sure you have the base folder. as the linked post implies some setups will only have “/var/www/” as base folder so that is what you need to use.
I simply did “md /var/www/html/iso”#2. place the ISO file(s) into the new folder you created in step #1.
#3. make sure that the new folder and all files in it is owned by fog user and fog group
“chown -R fog.fog <your folder name here>”#4. using Fog WebUI, create new menu item using parameter “initrd http://${fog-ip}/<your folder name here>/<Your ISO file name here>.iso chain memdisk iso raw”
done. works well. for simple ISO booting.
PS>> one thing though, this is for booting directly from ISO.
there are several threads here and on WiKi dedicated to adding specific OS install options to FOG like Windows PE
or such. -
@vl1969 done like u say. getting this error.please see the attach
-
@tom-elliott i provide 1 GB the 3 gb ram. my iso size is 800 mb
-
@badhonsoam I can see the error message you deleted, it says no space left on device for pxe booting. The means that the size of the iso is larger than available ram to store the entire iso in memory.
You have to go the route of only passing the centos kernel and the init file system via pxe and then have the target computer connect back to the FOG server using NFS to get the rest of the image. Network (PXE) booting from an ISO image only really works when the iso image is small.
-
If you’re trying to boot a Linux distribution, I recommend mounting the ISO (or unpacking it) and booting it directly. Seems to work better in most cases.
Don’t even try to directly boot a Windows install ISO.
-
@quazz then what will be the parameter for windows and linux in new ipxe entry.
-
@george1421 i give more ram then iso. i provide 1 GB the 3 gb ram. my iso size is 800 mb.

In my Fog Config, Advanced Menu settings I have these line items for calling windows install and Linux boot…
:Win7pex64 initrd http://${fog-ip}/opt/Win7/ISO/winpe_amd64.iso #prompt chain memdisk iso raw || goto MENU boot
:mint18_64 kernel http://${fog-ip}/opt/mint/18.1-cinnamon-64bit/casper/vmlinuz initrd http://${fog-ip}/opt/mint/18.1-cinnamon-64bit/casper/initrd.lz imgargs vmlinuz root=/dev/nfs boot=casper netboot=nfs nfsroot=${fog-ip}/var/www/html/opt/mint/18.1-cinnamon-64bit/ locale=en_US.UTF-8 keyboard-configuration/layoutcode=us mirror/country=US boot || goto failed goto start
Obviously you will need to setup matching locations with proper rights. There are articles, threads, etc that can help. I think Tom already listed some.
getting rights and NFS all to cooperate was the trickiest part.For Windows you MUST use the WinPE version. I tried to use a standard USB bootable and did not work. Had to be PE.
For linux I just used a version of mint. Had to use it extracted. As in not the iso and link to the boot files.
Now there were some changes to Apache(at least Fog’s implementation) as well that may affect the path(s) you can use. To be honest I haven’t tried this in awhile. You may have to tweak your paths to work or Apache settings.

@knightraven If you don’t mind I’b going to
borrow this
for the tutorial I’m working on. -
@george1421
You’re are welcome to use anything of mine. In fact I think you helped get the windows boot working awhile back. I’ve borrowed and tweaked just a bit from sources here at Fog anyway myself.I have to much going on right now to test what I posted but I know it has worked. My current location has a bare bones setup just for deploying an image. I haven’t had time to setup the advanced menu items(well the actual files anyway).
