I tried dd-ing the ISO onto a USB stick, as suggested in http://wiki.centos.org/Manuals/ReleaseNotes/CentOS7, but it didn't boot. Did anyone have better luck with this?
In any case, I got it working by running livecd-iso-to-disk on a Fedora-20 laptop. I've found before that this is the best program around for the purpose.
But I've 2 queries about this:
Why isn't this program available on CentOS?
I find it strange the using a USB stick
seems to be regarded as an out-of-the-ordinary idea. Are people still burning CDs or DVDs? And if so why?
I would have thought the time had come to make USB sticks the standard installation method? Certainly it should be treated on a par with DVDs.
I have two HP MicroServers running under CentOS, and these don't come with a DVD drive. I assumed this was becoming more or less standard?
I did all of my test installs from USB, so it does work.
The command is:
dd if=./<name>.iso of=/dev/<device>
Obviously the name would be something like: CentOS-7.0-1406-x86_64-DVD.iso or CentOS-7.0-1406-x86_64-NetInstall.iso or any other of the isos
It is critical that the device the the device name and not a partition name. In CentOS-6, you can use "Application => System Tools => Disk Utility" to find your USB stick's device name. For example, /dev/sdd (device) would be used, not /dev/sdd1 (partition)
You also have to run the command as root.
So, a working command would be, as root (if your usb stick was /dev/sdd):
dd if=./CentOS-7.0-1406-x86_64-DVD.iso of=/dev/sdd
I have boot that exact USB stick on an older BIOS only Dell Laptop (m4500) with no UEFI, a new Thinkpad with UEFI secure boot mode on and off, and a M5A99X EVO R2.0 motherboard with UEFI and secureboot on and off. Installs were conducted on all with no issues.
