I have a ASUS M5A97-R2.0 motherboard, with an AMD 6300 6 Core 64 bit processor. The BIOS is UEFI compatible. The first OS my buddy and I installed was CentOS 6.5 which used the "Old Style" Installer. I like using Standard Partitions and have been configuring my machine for some 16 years. Usually my Standard Partitions are /, /usr, /home (usually as primary partitions") and my extended partitions are usually /var, /tmp, /vm (for my virtual machines) and /backup ( for backing up the machine in case of crashes). Recently after experimenting with CentOS 7.0 as a virtual machine we decided to blow out of 6.5 (AFTER we backed up everything!!) and installed CentOS 7.0. I am the "Official Test Guinea Pig" whose job it is is to see what problems we might encounter along the way.

The first PROBLEM I encountered with CentOS 7.0 (and further explorations show I will encounter with RHEL 7.0 and Fedora 20) is that you have changed the Installer to this new fangled thing. It took me almost 2 DAYS to install the OS. I was forced to basically accept the OS automatic "Standard Partitioning" scheme that included both a /boot and a /boot/efi partitions, neither of which I needed under CentOS 6.5. After bouncing around I said "Fine, have it your way", and then went on to finish the install. I finished the basic updating, configuring of KDE 4.x desktop etc., and now came the time to add specific hardware and utilities, and drivers. My buddy set up his machine using the automatic LVM system. It should be pointed out both machines are mirror images of each other. The first package we installed was VMware Player. This is a package we have used for years without many problems, and worked well in CentOS 6.5. The first thing we are greeted with is the following message: "Before you can run VMware, several modules must be compiled and loaded into the running kernel". You press "Install", and you get the following message: Stopping VMware Services (OK) Compiling Virtual Network Device: Running Depmod (OK) Starting VMware Services (FAILED) . My buddy though he used a different installation came up with the EXACT SAME PROBLEM.

OK moving right along we next decided to install nVidia Accelerated Graphics drivers. both machines have ASUS Geforce 640GT graphics cards in them with 2GB of DDR3 memory. Neither of us had any problem installing these drivers to work under CentOS 6.5. While I had no problem "installing" the driver it promptly hung and I could not get it to log in. My buddy, I suspect because of a slight different install process, was first confronted and asked to install some "signed certificate" or some other such thing. Then it downloaded, then like my system promptly hung up.

Now 0/2 we set our sights on playing music CDs -- surely this would work. I installed a music CD and selected Rhythmbox hit PLAY ... (more)

UEFI is your system firmware. The operating system can work with it - unlike BIOS - and you can turn on compatibility mode to get something more like what you're used to. I think a lot of the confusion here comes from being unfamiliar with UEFI, and with the requirements of modern OSes - for example, you must have a /boot/efi partition for UEFI booting, and /usr/ must not be a separate partition these days. That said, I don't see a real question here. If you can try using Fedora, narrow down the problems, research and ask questions as needed for one thing at a time we might be able to help you here.
