Did you try to disconnect the USB device before booting the station ?
Perhaps it’s detected before the SATA one.
I never had problem with this kind of workstations.

as source, not from CD/DVD. So you should just leave the source selection on default.
The last time I used the netinstall CD (on CentOS 6, not very many months ago) it asked for a URL, not a CD.
You may want to look at the yum “shell” option (man yum-shell).
The dvd iso and netinstall approaches are very different. The dvd has everything while netinstall assumes you pull the packages from somewhere. If I’m doing more than one machine I always pull all the packages to a local machine and use that for my netinstll source.
Using boot pxe or netinstall with online mirror ;)

Read the man page. What you are suggesting is not how it works.
Actually what you said was:

so did you do (are you doing) a netinstall, or an install from DVD?
Isn’t DVD1 a bootable iso and, along with DVD2, a comprehensive package set? I.e., if you have DVD1 (and ideally 2) why would you do a netinstall?
The CentOS-7 netinstall iso at least does give an option for using a cd/dvd based iso as the package source, but the default is one of a range of network based options.
No, unetbootin is pretty unreliable. I’ve actually not had it work reliably with Fedora ISOs since forever, but I mainly use (U)EFI
systems is possibly why, but it doesn’t appear to rewrite the bootloader stuff correctly at all. At this point I’ve totally given up on it.
Fedora liveusb-creator ought to work. But… And it’s also currently undergoing a rewrite. The most reliable way to create USB stick media for CentOS and Fedora is dd.
Seems suspicious to me yes. A netinstall uses a network source, there are no packages on the netinstall media itself.
OK I just ran the CentOS 6.7 netinstall ISO in gnome-boxes and it’s not the graphical anaconda that I’m used to with Fedora. There’s an
“installation method” and it has Local CD/DVD selected at the top, but that clearly needs to be set to URL or it’s simply not a netinstall. And then you need to give it a URL for a mirror, like this:
This is preconfigured in Fedora for their netinstalls. I have no idea how CentOS does it, but it doesn’t appear to be ready to go.
yum group list
yum group list hidden
yum group install “group name goes here” “another group name goes here”
It contains the packages on the media. Netinstalls grab the latest versions of the packages. If you do a netinstall, and then a yum upgrade after rebooting, nothing needs to be updated. If you download even CentOS 6.7 and do a yum upgrade a bunch of stuff will get replaced.
“shell” is a yum command, invoked as shown below. I don’t believe there is any program called “yum-shell” (even though that is the man page reference).
shell Is used to enter the ‘yum shell’, when a filename is
specified the contents of that file is executed in
yum shell mode. See yum-shell(8) for more info.
yum shell [filename]
The contents of the file need to be standard yum-acceptable lines. I.e., the lines of a package list would need to be edited to include
“install ” and/or input continuation characters, etc.
I suspect not.
yum shell pkginstalllist.file
where you have prepended “install ” to each line (and I believe added
“run” at the end) of that file would seem to be likely to work. A
simple vi or perl search/replace edit/one-line script should get you the input file you need.
Since you have an interest in this I’ll let you read the man page and do the experimenting.
yum install $(cat pkginstallist.file)
yum install `cat pkginstallist.file`
should work unless that list is stupid long.

This it is a very easy process to create an installable usb key:
1. Download the iso file from a mirror.
2. Check the sha256sum with this from the command line:
3. verify the output is the same as this list (for CentOS-6.7):
4. Find the name of your USB stick, from the command line (as root) you can do:
fdisk -l | grep Disk | grep dev | grep -v mapper
You can also use the GUI disk tool
5. Use this dd command to copy to a usb stick:
dd if= of=/dev/ bs=4M
so if the usb device for the key is /dev/sdc , and you are at the CLI
and in the directory where the iso file is at (as the root user), then the command to copy the NetInstall iso file to usb is:
dd if=./CentOS-6.7-x86_64-netinstall.iso of=/dev/sdc bs=4M
Netbootin may or may not work (I have had problems trying to use it), but just dd’ing the iso file to a usb stick will.
