      @dureal99d Now that you have clead up your exports file it seems like you need to add those again. Please change your last entry to /opt/bootimgs/16.04.1_64 *(rw,sync,no_wdelay,insecure_locks,no_root_squash,insecure) and see if it boots up.

      Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

      Please support FOG if you like it: https://wiki.fogproject.org/wiki/index.php/Support_FOG

        OK lets step back and regroup here. Lets do the following

        1. Insert the Centos 7 dvd into your FOG server’s cdrom drive
        2. Key in the following commands into your fog server’s console as root:
        # we are going to put all of our boot images into the web server and issue the files
# with apache and cut out all of this NFS crud
mkdir /var/www/html/bootimg

# connect to the centos dvd to the /mnt directory
mount -o loop /dev/cdrom  /mnt

#show me there is content there
ls /mnt

# Create a destination directory for the centos installer files
mkdir /var/www/html/bootimg/centos7x64

# Copy the content of the dvd to the proper location
cp -r /mnt/*  /var/www/html/bootimg/centos7x64

# Change the access level for world read
chmod -R 755 /var/www/html/bootimg/centos7x64

# Unmount the dvd drive since we already have the files
umount /mnt
        1. Now in the FOG Configuration->iPXE New Menu Entry enter the following:
          Menu Item: Centos7PXEInst
          Description: Install Centos x64
          Parameters:
          initrd http://${fog-ip}/bootimg/centos7x64/images/pxeboot/initrd.img
          chain http://${fog-ip}/bootimg/centos7x64/images/pxeboot/vmlinuz initrd=initrd.img method=http://${fog-ip}/bootimg/centos7x64/ devfs=nomount ip=dhcp
          boot || goto MENU
          Menu Show with: All Hosts
        2. Now pxe boot your target computer and select the Install Centos x64 menu item.
        3. You should see the installer boot and run.

        This process can be replicated to other linux distributions. I just tested this, this morning on my dev fog server running 1.3.0-rc8 and it works.

        As for a live boot, these settings don’t work, the installer still runs. I don’t have time right now to figure out why the live boot bits are not working.

        Live OS boot

        initrd http://${fog-ip}/bootimg/centos7x64/images/pxeboot/initrd.img
chain http://${fog-ip}/bootimg/centos7x64/images/pxeboot/vmlinuz initrd=initrd.img root=live:http://${fog-ip}/bootimg/centos7x64/LiveOS/squashfs.img ip=dhcp rootflags="loop" rootfstype=auto ro rd.live.image quiet rhgb rd.luks=0 rd.md=0 rd.dm=0 
boot || goto MENU

        Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG!

              /opt/bootimgs/16.04.1_64 *(rw,sync,no_wdelay,insecure_locks,no_root_squash,insecure)

              it works now, I see I had this line “nfsroot=${fog-ip}:/var/www/html/bootimgs/16.04.1_64/” wrong.

              I had nfsroot=${fog-ip}:/bootimgs/16.04.1_64/ which did not work but once I seen the path @george1421 was using I realized I had nfsroot= wrong.

              thank you all @Developers . all I have to do now is try the cent os method made by @george1421. I’m on that now

boot || goto MENU

                @george1421 This worked like a charm. Cent os boots, I have to do the net install type but it boots and is able to be installed.

                Thank you all.

                Side note, this should work for fedora? yet fedora is refusing to boot. I think because fedora does that live boot thingy. gices this error >>dracut: FATAL: No or empty root=argument dracut: Refusing to continue. yet this thread is solved.

                  @dureal99d The live boot bits that didn’t work for centos was from a fedora pxe boot guide. That is all I did and then just translated what was needed for the structure that fog uses. You will get much faster boot speed with http over ftp, or tftp that is why I kept everything in the same protocol by specifying http:// when making an object reference.

                  Also from my instructcions I moved the files out of the fog directory where they will get clobbered when you update FOG. By putting them on the web server in a different root folder (i.e. not /fog) the fog installer scripts will not touch them. It would be very depressing if you created this monster boot menu and then have a fog upgrade eat all of your hard work.

                  Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG!

                    fedora pxe boot guide.

                    @george1421 I have moved from the files from the fog root and moved them to /opt/bootimgs/ then I created a soft link to them as suggested by @Wayne-Workman . So no more fog eating the files on every upgrade. thank you. I am going to start reading up on all these codes so I can have a better understanding for these situation.

                    at any rate if you find you get the time a fedora code would be nice but not all that needed. oh and i almost forgot to post this.

                    Working boot menu for all but “centos live” and “fedora”

                    Hope this helps make someone’s life a bit easier now or later

                      @Developers @Moderators @Senior-Developers I wanted to update this thread with my current progress. both are working bootable.

                      in virtualbox i had to have at least 1650 gigs of ram allocated for it to boot. anything under that and it will error out. but i expect most machines these days to have at least 3 to 4 gigs of ram so any who choose to use should be fine.

                      Hope this helps make someones life a bit easier.

                      both are fully working

                        @Wayne-Workman Here is an updated working centos boot code that works for using your own downloaded repo as well as the online repo.

                        I downloaded my own repo using command <wget -r -l 0 ./LOCAL-DIR WEBSITE-URL> in Ubuntu.
                        once downloaded
                        I then copied the repo from my home directory to the /bootimgs folder.
                        I then modified the boot code originally provided by @george1421 from:
                        :centos
                        initrd http://${fog-ip}/bootimgs/centos/images/pxeboot/initrd.img
                        chain http://${fog-ip}/bootimgs/centos/images/pxeboot/vmlinuz initrd=initrd.img method=http://${fog-ip}/bootimgs/centos/ devfs=nomount ip=dhcp
                        boot || goto MENU

                        to

                        initrd http://${fog-ip}/bootimgs/centos/images/pxeboot/initrd.img
                        chain http://${fog-ip}/bootimgs/centos/images/pxeboot/vmlinuz initrd=initrd.img root=live:http://${fog-ip}/bootimgs/centos/LiveOS/squashfs.img ip=dhcp repo=http://192.168.1.109/bootimgs/centosrepo/mirror.nodeshosting.com/centos/7.2.1511/os/x86_64 splash quiet – || read void
                        boot || goto MENU

                        the end result is that now I have my own home repo that works even if my machine is not connected to the internet. I assume this is good for corporate or environments where the admin is not wanting to use much data from or restrict the net.

                        it also makes short work of the install time.

                        I hope this makes someone’s life a bit more easier
