Generally, After building a new kernel, I issue 'update-grub' command on my ubuntu box to add proper entries for the newly built kernel in the grub configuration file, but I think 'make install' will take care of this as well. However, as you've confirmed that you've successfully booted from the newly built kernel, which is still being reported as a 32 bit kernel, therefore we can safely reject the case of incorrect and or missing grub entry. Do you see compressed x86_64 bit kernel image(vmlinuz-<version>.x86_64) under /boot ?

Please don't do top posting :) anyway, try to use: make install Usually it will take care of copying the kernel image to /boot, rename it to vmlinuz-<kernel version> along with the initrd/initramfs, plus it will set the boot loader entry for you :) -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com

Hi Mulyadi,

Please explain below step which you have mentioned? I have bzImage (64bit) in my x86/boot/. What should I do to create a ISO image.

Are you trying to build a ISO 9660 aka. Compact Disk (aka. CD) image? If so, have a look at ISOLINUX.

A good description of what "top-posting" means can be found here: http://www.idallen.com/topposting.html I see you seem to use Microsoft Outlook. That makes formatting emails nicely (to the standard of technical communities which have their roots in UNIX culture) a bit harder. Thanks, Jonathan Neuschäfer

Thanks Jonthan/Santosa,

I could make a ISO image with Debian. My kernel was not booting earlier as I was booting wrong image. With new ISO image, still I did not get login prompt yet:(. Debugging the issue.

Glad you made it :) good luck -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com

Can you look at the 'running' kernel's config to see if it's indeed the one you compiled (provided you enabled support for it during building - see /proc/config.gz)? Eg something like 'CONFIG_X86_64=y' is set. Is the machine you're building on 64-bit or 32-bit? I hope you used a 64bit compiler for building your kernel. HTH, -mandeep
