I'm not very familiar Linux and I would really appreciate a bit of help. I manage Windows servers and workstations. We have one Dell T7500 workstation which is running Red Hat 6.5. This workstation is changing hands and the new user requested to have Windows installed, but wanted to keep Linux. I discovered it had a Virtual Machine Manager in System Tools, so I set up a Windows 7 VM which works great.
I noticed Red Hat has a software update available so I ran it. It said there was a package conflict (due to being from different sources), so I canceled the update. The machine was running fine at this point. I decided to check the BIOS out to make sure virtualization support was enabled. It was, but Hyper-Threading was disabled. I could make changes because there was an Administrative password preventing me from doing so. I reset the password via the MB password reset jumper. This cleared the password. However, at this point I could no longer boot. I receive the error:
Kernel panic - not syncing: Attempted to kill init!
PID: 1, comm: init Not tainted 2.6.32-431.23.3.el6.x86_64 #1

I don't know if it was the software update conflict which did this, or removing the password in the BIOS. Thanks for you help.
