[gPXE] Linux instalation using linux iso image.

[sivakumar siva kumar]

Sir,

   Thanks for your replay & sorry for the delay in my replay.

It is unclear which component (gPXE, BIOS, Linux kernel, distro
installer) is displaying this error message..


   I am using 1.0.0 . I am using linux kernel 5.5 & 5.3. Bios it is an Cisco blade with there own bios.

Your comments:The following commands work for me, I just tested with RHEL 5.5 and a
KVM virtual machine:
dhcp net0
kernel http://10.0.2.2:8000/isolinux/vmlinuz askmethod
initrd http://10.0.2.2:8000/isolinux/initrd.img
boot 


When i give this cmd it is working fine and with out error I am going to nex line. But when i give boot cmd it says no unique boot image is found.

I loaded the iso image in http service and it is working fine.

I don't know  what mistake I am doing . Or it may be an issue of my bios. I am attaching the screen shot please review it.

Thanks & Regards.
Siva Kumar.

Please keep the gpxe at etherboot.org mailing list CCed. That way others

can follow the conversation and make suggestions.

It is unclear which component (gPXE, BIOS, Linux kernel, distro

installer) is displaying this error message. Can you give more

details about your configuration and what happens before you see the

error message?



The following commands work for me, I just tested with RHEL 5.5 and a

KVM virtual machine:

dhcp net0

kernel http://10.0.2.2:8000/isolinux/vmlinuz askmethod

initrd http://10.0.2.2:8000/isolinux/initrd.img

boot



The HTTP server is listening on 10.0.2.2:8000 and exports the entire

RHEL 5.5 ISO contents. The ISO was mounted with "mount -o loop

RHEL5.5.iso /mnt" and the HTTP server has /mnt as the server root.

The kernel and initrd paths therefore need to point into the isolinux/

directory (i.e. isolinux/vmlinuz and isolinux/initrd.img).



I use "askmethod" on the kernel command-line so that the installer

prompts whether to install from CD-ROM, HTTP, FTP, etc. When HTTP is

selected, there is a dialog to enter the hostname/ip of the HTTP

server and the path, I use "10.0.2.2:8000" and "/".



When you run the commands above, you will see gPXE download the kernel

and initrd. Then Linux boots and kernel messages scroll past - at

this stage gPXE is not used anymore and Linux has taken over. Then

/sbin/loader starts the distro installer and menus appear to select

your language, keyboard, and installation method. At which stage are

you seeing the error message?



Also, I noticed in your original email you wrote "insolinux" instead

of "isolinux". Is that a typo in the email or did you really use that

in the command?



If you're still stuck, consider sending a screenshot when the boot

stops with an error message.
