Hi, My server not able to boot up. It is hanging after few times. How to repair boot system? I am trying to use grub2-install. Is it necessary to install grub2 on boot device?
Please help.
Thanks in advance.
Hey,
You'll need to be a bit more specific on how it hangs and when. Which part of the boot-up sequence, is there any errors on screen, and so on.
Best regards,

Does the system boot with a Live USB system?

I can boot from DVD. I deleted kernel. Thought it will fix the problem. Now I can see rescue menu only. Kernel source is there. How to get back kernel.

You have to boot from a live boot disk, chroot into your old system's filesystem, mount all partitions properly and then download and rebuild the kernel and grub config. You can try just "yum install kernel" aswell, but I'm not sure whether it'd work.
Best regards,

The install DVD has a system rescue menu option.
