On the other hand, people should know the Minimal really sucks: * No dual-boot set up. It just blithely wiped out the ability to boot up Windows. At some point I'm going to have to recover my Windows install because of this install. Every Linux install I've ever done-- out of hundreds of them and going back to 1992-- has gracefully and easily set up a dual-boot. The README should at minimum mention that. Better yet, the install's name should be given "Non-dual-boot.iso". * The resultant OS was text only. I.e., it wouldn't run init 5... trying to do so would cause to hang. * Maybe the above problem was due to bad coding somewhere-- the entire OS horked a couple times... then I finally saw error code saying, "kernel panic". I haven't gotten one of those in decades. Geez, what a terrible ISO distro!

Dual-boot is not a typical or supported use case for RHEL. Dual-boot can be set up manually by editing /etc/grub.d/40_custom: menuentry "Windows" { set root='(hd0,1)' chainloader +1 } Adjust (hd0,1) to match the partition number where Windows is installed. Run "grub2-mkconfig -o /etc/grub2-efi.cfg"> * The resultant OS was text only.

Minimal is useful to experienced admins who want to build a very small system image with only the specific packages they need. It can be used to build a desktop system, but that's a lot of work (or knowledge). You would have been better off with CentOS-7-x86_64-DVD-1511.iso or CentOS-7-x86_64-LiveGNOME-1511.iso (or KDE). I apologize on everyone's behalf for not contradicting that advice.> * Maybe the above problem was due to bad coding somewhere-- the entire > OS horked a couple times... then I finally saw error code saying, > "kernel panic". I haven't gotten one of those in decades.There's not much to go on there. We have no idea what caused the panic, whether it was a bug or not.> Geez, what a terrible ISO distro!I don't think that's a fair assessment. CentOS (and RHEL) is one of the most stable systems I've ever used.

It used to be that info was (eminently sensible) on the same webpage. We're getting away from sensible webpages.> >> It's good to have all this info together in one email. >> >> On the other hand, people should know the Minimal really sucks: >> >> * No dual-boot set up. > > CentOS is a rebuild of Red Hat Enterprise Linux, whose target use case > is business servers and workstations. Dual-boot is not a typical or > supported use case for RHEL.I figured it was a simple hand-off from RH. Just because it's from RH doesn't means it makes sense. It also doesn't necessarily mean that CentOS couldn't do a better job of it... especially that it horks dual booting.> > Dual-boot can be set up manually by editing /etc/grub.d/40_custom: > > menuentry "Windows" { > set root='(hd0,1)' > chainloader +1 > } > > Adjust (hd0,1) to match the partition number where Windows is installed. > > Run "grub2-mkconfig -o /etc/grub2-efi.cfg"Thanks much for that. I'll give that a try. The question arises, if it's this easy to do by hand, why couldn't the code (if not from RH, then at least from CentOS) build a little option in to preserve dual-booting (for many folks who don't have a helpful dude like yourself nearby in the email list)?> >> * The resultant OS was text only.

The installed OS hung once, black-screened, and a third (and last) time hung with "kernel panic" (and a lot of other error language). I checked the web if there was any mention of problems with linux with my cpu, but found only people mentioned video configuration (not relevant in this situation). I've been using Windows for several days and had zero problems which would indicate any hardware problems. Maybe other folks would need to see if they're having the same or contrary experience. Until then, I have to stand with my assessment.> >> Geez, what a terrible ISO distro! > > I don't think that's a fair assessment. CentOS (and RHEL) is one of the > most stable systems I've ever used.I mean only the Minimal v.7... this distro-package, not CentOS or RH altogether. I've been a fan of the latter for a long time. Even rarely RH can squeeze out a real hot stinker.
