Hi there,

I have a problem booting my Centos installation for testing.
I've edit the grub.conf file and edit the line root=LABEL/ to root=/dev/sda4.
I also edit my fstab to point de / partition to /dev/sda4.
then I also renamed my initrd in /boot to initrd-<kernel-version>.img.org.

I would like to fix this problem, so i boot in rescue mode.
Linux cannot mount my image, so the only directories i have in /mnt/sysimage is boot, proc and sys.
I am able to modify the grub.conf, but not my fstab. Also I cannot make a new initrd with mkinitrd command (command not found).

How can i make a new initrd file again to be able to boot my pc?

thanks

Once you have booted the Live CD you should be able to chroot into your original / and 'mkinitrd' from there. However that requires access to your /, so
why won't it? What errors does it show? What HW setup do you run?

I found the solution.

fdisk -l (to check the partitions)
e2label (to find the / partition)

mkdir /rootdirectory (eg mnt)
mount /dev/hda2 /rootdirectory (eg mnt)

once the / partition is remounted you I could fix my /etc/fstab.

Then reboot again in rescue and do a mkinitrd to make a new initrd file.
