If you can install the kernel, when booting you get a few seconds to change the kernel which is booting, so select kernel-3.10.0-957. If you can successfully boot to it, do a "yum remove kernel-3.10.0-327.3.1.e17" to get rid of it. Check the dependencies before hitting "y".

ClearOS uses grub2 to boot so search for something like "grub2 centos change boot order". Anything which works for Centos should work for ClearOS, perhaps tweaking for file names. If you do a legacy boot, you do not need to do anything which creates the UEFI boot stuff. You may find that just removing the bad kernel sorts out the boot order.

Thanks for the reply. To answer some questions: I am running Clearos 7 Home edition. For clarity, I can install the kernel. When I do a....... yum list installed kernel .........after I install it the kernel appears with the old kernel as the primary operating kernel. The issue I encounter is booting with this kernel. My current kernel and setup is using legacy boot. Does this change any of your response

How have you got into that position. The only kernel you have is an el7 kernel, which, up to last Tuesday, we do not provide, and your version is old. Is yours a recent installation or an old one, and is it Community, Home or Business? If you have the devel package I assume you have been tinkering and deleting older kernels - ClearOS usually keeps somewhere between 3 and 5 old ones available do you can switch on boot, but they do not keep the older ones in their repos apart from the base one in the clearos repo.

Try booting off an installation cd into rescue mode. The try to do:

yum install kernel-3.10.0-957.10.1.v7

As that is still available.

If you then upgrade to 7.7 you'll get 3.10.0-1062.1.2..

The version are not the same of the files.
Maybe your can try to install them again per file.

yum install kernel-3.10.0-957*
