Make USBKey media for CentOS 8 install media

Post by warron.french » 2019/12/28 05:25:45

I am running Windows 8.1 on my hardware where I am writing this message. I have another machine that does not have CD/DVD drive so I need to be able to create a bootable USBkey for a CentOS 8 installation.

I found this link, https://wiki.centos.org/HowTos/InstallFromUSBkey; however, it does not specify CentOS 8 in its instructions.

I have two questions:
1. Can I use my Windows 8.1 machine to extract the ISO from my Windows 8.1 OS the following specific ISO (CentOS-8-x86_64-1905-dvd1.iso) so that I can make the USBkey media usable?

2. Can I use the instructions from the link provided?

Question: I do have CentOS 7 and also CentOS 8 running within Oracle VirtualBox. Can I perhaps mount the USBkey in Windows, then to a CentOS virtual machine within Oracle VBox, determine its drive label (/dev/sdX ?) and then use dd to extract the CentOS-8-x86_64-1905-dvd1.iso to that USBkey?
Thanks,
War

The instructions on that link are applicable to any current CentOS version. If using Windows then avoid all the broken utilities listed in that article.
CentOS 6 will die in November 2020 - migrate sooner rather than later!
CentOS 5 has been EOL for nearly 3 years and should no longer be used for anything!

After using Win32 Disk Imager to extract the CentOS-8-x86_64-1905-dvd1.iso to my USBkey device all I see is the folder EFI on the drive. I also observe that out of an 8.0GB USBkey there is only 464KB free.

Does this make sense?

Unless you have a 3rd-party driver/service, or a GUI like Paragon's Linux File Systems for Windows, yes - it makes sense to not be able to read the stick with windows. If you can boot from it, the first option offered should be to scan itself... if that passes, it should continue booting to the installer.
