Centos 7/1503 -- Getting Error setting up base repository during installation

Question

I've created bootable USB flash drive using recommended LiveUSB Creator using CentOS-7-x86_64-Everything-1503-01.iso.

Now being at Installation Summary screen I'm getting Error setting up base repository. When I click on Verify at Installation Source screen I get This media is not good to install from. Rather cryptic error message...

I've also tried switch to On the network and insert http://mirrors.kernel.org/centos/7/os/x86_x64 with no success.

Additional info: Installing on HP EliteBook 8540w

When choose _Test this media..._, it seems that it doesn't test anything at all. Now I've noticed this message during boot process: _A TMP error occurred attempting to read a pcr value_ But it doesn't explain why even network repository doesn't work. — daneel, Aug 03 '15 at 17:12
It seem's to be. Getting MD5 sum 186b049a88b18f7d43e03eed72247c76 as I can read on http://ftp.cvut.cz/centos/7/isos/x86_64/md5sum.txt — daneel, Aug 03 '15 at 18:58

You have an error in the mirror URL (and extra x at x64) it should be http://mirrors.kernel.org/centos/7/os/x86_64.

Fixed it for me, today (without clicking the checkbox for mirror link). I had tried three other URLs before, from different FAQs and guides. – Law29 May 30 '18 at 09:40

tried, it didn't help me – Steve Yakovenko Jun 02 '19 at 20:16
In my case I was installing CentOS from a netinsall iso on a VirtualBox VM. I would have expect the installer to provide a default source but it didn't, using this url as the source solved my issue. – Julien B. Jan 03 '21 at 19:25
**Everyone Please make sure your interface is enabled**, then only it can contact mirrors. I think in installation step they should give a warning to enable this !!!! – Arun Jun 30 '21 at 13:07

Do not use LiveUSB creator, it doesn't work with this release of CentOS.

I had the same problem, I recreated the USB flash drive using dd under Linux ( dd bs=4M if=CentOS-7-x86_64-Everything-1503-01.iso of=/dev/sd[letter of your USB drive] ), and it worked like a charm.

If you do not have access to a Linux machine, you need to report this problem to LiveUSB-Creator developers and/or CentOS developers.

when you install centos 7 on network, you may config installation source.

when you input the url under the label 'On the network:', you'll see the check box already checked that means 'This URL refers to a mirror list' , disable that.

I experienced the same problem. It is working after I switch to Win32 Disk Imager.

Please try using another USB ISO burner. It should work. There is a list of working programs for the task.
