Scientific Linux 7 won't boot after yum updates kernel

[pointer]

Hi,
I did update with the command "yum update --enablerepo = sl-testing" and after update did not want my system to boot.
I have to use the old kernel to boot (3.10.0-327.18.2 e17.x86_64)
In kernel (3.10.0-327.36.2 e17.x86_64) and (3.10.0-327.36.3 e17.x86_64) will not boot
Please help me if you can.
Thanks

Till where does your system boot? What errors are you getting? Try booting the system press escape while the system is loading what are you seeing there?

On the other hand you are probably better off mailing the scientific user mailing list(scientific-linux-users):
https://www.scientificlinux.org/community/ Since you updated your system from a testing repo which is disabled by default, they might be able to help you if at all. But you are probably better off taking out your hard disk , connect it to a working system and mount the needed partitions. Backup all your files to another location, than doing a clean install. Since updating your system from a testing repo more than likely screwed up your system up to point where it's probably not likely you are able to recover from it.
