I burned a boot USBkey with the command(from CentOS wiki):

dd if=CentOS-6.5-x86_64-bin-DVD1.iso of=/dev/sdb

After the command, I found my USBkey has beened wipe all partitions and it showed entirely freespace of my USB. However, I could find the USB-booting option in my computer's BIOS after rebooting and it shows the installation UI, and thus I think it will work on server too.

So I reboot my server lenovo x3650m5(PS: I have found that RHEL6 support the server, so CentOS is supposed to support it), but it failed-it found the USB, but it couldn't load the booting system.

Did I miss anything needed for the boot operation on the server?

  • Is the USB stick defective or counterfeit? – Michael Hampton Oct 22 '16 at 05:57
  • @MichaelHampton No, it's legal `Kingston Data Traveler SE9`, and finnally it worked after I had to turn to `rufus` on windows to reburn it. I'm just wondering if it's the formal solution from [CenOS Wiki](https://wiki.centos.org/HowTos/InstallFromUSBkey), and I follow the solution, why failed? – huangjj27 Oct 22 '16 at 06:06

I have heard people say that some USB sticks boot after dd and some don't, and have had the same experience myself - seems some combinations of USB/motherboard work, and some don't.

Try a different USB stick.

It seems that it is the server can't recognize any bootinUSB burned by dd, and I finnally walked around the problem by using rufus to burn again on win10.
