recover from boot failure initramfs

HI guys,

Can anyone shed some light on this article? https://access.redhat.com/solutions/365693

i have a test system that will not get past the initramfs stage at boot after a kernel update and the first command in the article "chroot /mnt/sysimage" fails because a linux filesysystem was not found by the rescue disc before that.

Due to that I am not able to run the dracut command to recreate the initramfs which I hope would resolve the boot error.
