@george1421 Sorry for the late reply. The menu entry does work now. We have sda and sdb drives in our computers and wish to specify the sda drive for all the imaging with a parameter. The images are captured in single disk.

Edit: just to specify the idea behind the 2 drives. We have computers that students are using where sdb is always a Windows 10 image but the sda serves as “playground hard drive” where students can install anything they want. We intend to create premade ipxe entries for the deployment of different operating systems and can now do it thanks to your help. This sda/sdb targeting is the only thing we were left wondering about.

@george1421 Hi, thanks for the answer. We managed to get an option in the fog ipxe menu that deploys the image we want perfectly, now we have an issue with how to choose the specific drive, sda or sdb.
These are the parameters that we used: “ip=fog server ip”

params
param mac0 ${net0/mac}
param arch ${arch}
param qihost 1
kernel bzImage loglevel=4 initrd=init.xz root=/dev/ram0 rw ramdisk_size=127000 web=http://"ip"/fog/ consoleblank=0 rootfstype=ext4 mac= ftp="ip" storage="ip":/images/ storageip="ip" irqpoll chkdsk=0 capone=1 type=down img=XubuntuTesti imgType=n imgPartitionType=all imgid=32 osid=50 imgFormat=5
imgfetch init.xz
boot

Any ideas how to specify the drive in which the aforementioned image deploys?
Thanks a ton for your help George!

@george1421 It would be a fog captured image.

We have fog 1.5.5 in a virtual server where we have been trying to create an iPXE menu entry from the fog management GUI to deploy a specific image on a registered host, without usernames or passwords.
What parameters should we use to make it happen?
We have found some examples from the web that we have tried but since we are pretty new with fog and iPXE, we couldn’t make them work.
