CENTOS Installation Problems


I have been trying in vain to install CENTOS 7 onto a new disk in a dual core PC. Tried the USB route, using UUI and UNETbootin. No luck. Tried the DVD route. No luck. Firstly I downloaded the latest ISO for CENTOS and extracted it to a DVD. Right or wrong? I changed the BIOS to make booting from DVD the priority. Installed the DVD and powered up the PC. Gets as far as GRUB and no response. No CENTOS start-up screen. Took a look at my RHEL_64 Linux CD and notice that there is an autorun file at the top of the first disk. This is missing on the CENTOS version. Any help would be appreciated.
With respect to the USB route, both UUI and UNETbootin methods failed on the same ISO extracted file on my USB memory stick (64GB).
Tried other official ISO files and no success.
Files tried:

CentOS-7-x86_64-Everything-1503-01.iso
CentOS-6.6-x86_64-minimal.iso

Feel sure I must be doing something wrong or everyone would be reporting this.

Wrong.

The .iso file should be burned to DVD as a bootable image. You cant just extract files to it and expect it to boot.

Are you using Windows, Mac, or Linux to make this DVD?

Edit: just noticed your Windows icon. Stick a blank DVD in your DVD drive, right click on iso file and select burn to disc. This will make a bootable disc. I think there tabs on top that says Burn to disc as well, cant remmeber, havnt done this on Windows in some years.

2nd edit: You can also use 3rd party software to do this. http://www.winiso.com/support/tutori...table-iso.html

Also you can make a bootable USB if you have a flash drive big enough, I think 8gb will be ok. http://unetbootin.github.io/

I have installed Centos 7 minimal more than once, from a DVD I burned from the ISO, or the ISO connected to a virtual machine. You don't extract an ISO file to a DVD, just burn it as is.

"no luck" is a bit slim in terms of problem description. Can you tell us more?
Can you start any Linux installation? Or other OSs?
"Gets as far as Grub and no response" - what's on the screen? Any reaction if you press a key on the keyboard?

Thanks Eric. I expect this is my common misunderstanding on both DVD and USB, so will try again.

Thanks also for your response Berndbausch. I am not so familiar with Linux and ISO files, so am working in the dark at the moment. I have installed and use RHEL_64 Linux from CD, so I suppose I was a little spoilt. I do find Linux environment a little difficult, relative to Windows Visual Studio environment, but maybe I will get used to it over time. Having to provide a Linux driver for my hardware, having already created one for Windows 7, and feel like I am back in the 1980's in the Linux environment. Got the driver working, but need to make sure it is OK under CENTOS, which is what my customer is using.

Hello again Eric, Burned the DVD and got through the install process. However, when booting I only get to the command prompt, not to the CENTOS graphics desktop. I didn't mention that I was installing on a SATA drive. Do you know if this is a problem ? I re-booted, this time selecting rescue route and noticed that there is a problem. "conflict detected with stolen region: [0x7f800000 - 0x80000000]. Looks like ata2.01: exception ... is being reported. It is currently going through checking the DVD at the moment. Any ideas ?

I think this is what you get if you install from the minimal iso, or select minimal. Just a basic system without a desktop.

I have no experience with minimal installs, so I'm not sure. Someone correct me if I'm wrong or add info, but maybe all you need is to install a desktop environment like Kde or Gnome or whatever you like.

Here's some more info

Cent7 has a nice Gnome desktop GUI -- just like windows has "windows explorer" as a desktop GUI

windows has a terminal
though the linux terminal is way better

visually the two should "look" about the same - sort of

Seems like a bad burn of the ISO or a problem with the ISO file itself... Try doing it again, this time, if your DVD burning software supports and is using high speed burning,... don't use that (shouldn't take that much longer to burn at a slower setting).

CentOS, like Scientific Linux or RHEL will give you an option to install a desktop environment. If you are using CentOS as a replacement for RHEL (for RHEL cert. training, for example), you'll want to install the default Gnome environment.

These are the two iso the op tried

Files tried:

CentOS-7-x86_64-Everything-1503-01.iso
CentOS-6.6-x86_64-minimal.iso
From centos

CentOS-7-x86_64-Minimal-1503-01.iso
The aim of this image is to install a very basic CentOS 7 system, with the
minimum of packages needed to have a functional system. Please burn this image
onto a CD and boot your computer off it. A preselected set of packages will be
installed on your system. Everything else needs to be installed using yum. The set
of packages installed by this image is identical to the one installed when choosing
the group named "Minimal" from the full DVD image.

I appreciate all the suggestions here guys. I am currently loading up a 8GB HP USB memory stick with the CentOS-7-x86_64-Everything-1503-01.iso version to see if I can get any further. Takes a long time to get the memory stick loaded, so cannot provide feedback yet. Using Unetbootin for this. Loaded this up on a 64GB Verbatim memory stick, but the PC did not see it on boot, even though it was a FAT32 and USB boot was set up in BIOS.

With all this struggle, perhaps I should be asking if there is much difference between RHEL 4 (64-bit) and CENTOS 7 (64 bit) ? The main reason for trying to get CENTOS 7 installed is to test my hardware driver, which basically works under RHEL 4.

About another hour to go before the memory stick is loaded. Less painful if I throw myself under a truck yes ?? **

Any difference between RHEL 4 & CentOS7?!?! Of Course!!! CentOS is a source clone of RHEL, so all the differences between RHEL 4 & 7 will exist between RHEL 4 & CentOS7...

See from Wikipedia a reference to the diffs between RHEL versions:

You didn't have a GUI because you installed the "minimal" release. You don't need to reinstall the "everything" release to get a GUI though, just use yum. Everything the "everything" release installs is available in the repos.

From a minimal install:
Code:
yum update
reboot
yum groupinstall "Desktop" "Desktop Platform" "X Window System" "Fonts"
systemctl set-default graphical.target
reboot
and it'll boot into the GUI
