It appears that CentOS 7 was the last one with a 32-bit version. I'm trying to install it on an older laptop and having some trouble. I have CentOS-7-i386-Everything-1810.iso and have verified it. Using either dd or mediawriter to put a copy on a 16 GB thumb drive seems to work. But then the laptop reports, "no boot image found". Note that the first 32 KB of the iso is all zeros, meaning that there is no MBR or partition table included.
Depending on the age of the laptop, booting from USB sticks over 8 GB may not be possible. Larger usb images I believe use a different layout format (GPT?) which also may not work with older hardware. I would try a smaller one first and see if that works.
According to the 0_README.txt on the CentOS mirrors, the Everything ISO, "contains the complete set of packages for CentOS Linux 7. It can be used for installing or populating a local mirror. This image needs a 16GB USB flash drive as it is too large for DVD isos... You can burn these images to a DVD or 'dd' them to a USB flash drive. After the boot media has been prepared, boot the computer off the boot media."
Does anyone know what I don't understand about this procedure?
