Where can I find initramfs-2.6.41.4-1.fc15.i686.img or how can I generate one


After upgrading the kernel,I restart the computer.When I choose the new kernel vision,I met a problem below:
kernel panic -not syncing:vfs:unable to mount root fs on unknown block(0,0)

I can't find
"initrd /initramfs-2.6.41.4-1.fc15.i686.img"
in my /etc/grub.conf.

And there is no /boot/initramfs-2.6.41.4-1.fc15.i686.img in my computer.
Where can I find initramfs-2.6.41.4-1.fc15.i686.img or how can I generate one.


Here is my /etc/grub.conf:

splashimage=(hd0,2)/grub/splash.xpm.gz
hiddenmenu

how to generate initrd for fedora
turns up this link- http://www.ibm.com/developerworks/li...trd/index.html

The command you need is 'mkinitrd'. You need to read the details, its not hard to do.

This link is from Fedora doc - http://fedoraproject.org/wiki/Dracut

mkinitrd has been superceeded by dracut. You;; need to boot using the old kernel and run a command similar to the following (be sure to substitute your kernel version in the appropriate places; I'm using 64-bit Rawhide)
Code:
dracut -H initramfs-3.2.0-0.rc6.git0.1.fc17.x86_64.img 3.2.0-0.rc6.git0.1.7.x86_64
man dracut for details
