[RESOLVED] = CentOS ISO too big for DvD media

Post by warron.french » 2020/01/03 21:46:14

This file, CentOS-8-x86_64-1905-dvd1.iso, that I downloaded when the ISO first became available.

I can burn the ISO to a flash drive; however, it appears to be larger than a 4.7GB DvD. Was it really intended to be a BluRay DvD? If so, why not mark it as a different filename, perhaps -BDvD- instead of simply "dvd1"?

What do I need to do to install CentOS 8 on a machine that can boot from media, but I cannot get into the BIOS to alter boot order?

It will fit an 8.4GB (dual layer) DVD.
Remember - importing/building packages will likely "byte you in the butt" come update time, long after you'd forgotten you did that! Use repos whenever possible.

Great! The kind of DvD burner that I don't have.
Thanks,

Are you sure? Pretty much all DVD burners have been DL for about 10 years. DL discs came onto the market in 2003 and drives supporting them in 2004.
CentOS 6 will die in November 2020 - migrate sooner rather than later!

I would add that a significant proportion of DVD drives prior to 2003/4 can read a home written dual layer DVD, as all DVD's drives can read stamped dual layer disks. I would point out that this means that dual layer DVD readers predate 64bit x86, so exactly what is the problem with CentOS 8 only supporting an ISO that needs burning on a dual layer disc, bearing in mine 99% of installs will be from USB or virtual media?
