Keeping things simple is a matter of personal preference. On my desktop computer, I have Crux, SourceMage, Void, Gentoo, Arch, and Windows10 on 3 disks, a SSD and 2 HDD's (and I've tried many others). They are all booted from Grub Legacy (Grub1) which is located on the Gentoo distro. I have never had a problem booting anything. I have never used a separate boot partition. The 2 HDD's have at least 10 different partitions. Four of the Linux distros have custom kernels, I've never used "make firmware_install". If you plan on re-partitioning in the future (maybe to try another distro), id'ing your partitions with UUID probably makes sense. Device names can change, UUID's do not. That being said, I have always used device names.

Good luck, glad you got it installed. Crux is my favorite.

Ok Steve. I just installed it again following your instructions. It worked! I was not doing 'make firmware_install' when compiling the kernel. I am gonna keep it simple from now on. One os on each disk! I am reformatting my Ubuntu drive now. No more of that! Thanks again.

It's not a problem if you configure fstab correctly.  I never do because all of my crux machines are one physical drive and one partition per system, I don't even use swap. 
I just like to keep things clean and simple.

I am using gmail in the web browser, I must have hit a button accidentally to enlarge the font.. I am sorry about that. I think I have got it fixed now.  I don't see a reply all button. I thought I was sending all my messages to the group. 😯 I am CC'ing this message now.

One last question: Are you using a separate boot partition on your disk for your CRUX installation? I usually dont, and I am wondering it that may cause a problem.

Also your font in your last few emails is gigantic, is that intentional?  I've been CC'ing the crux list on my replies because you're not replying-to-all and I think the rest of the list may be able to help you better.  Good luck.  I'll help if I can.

Ok. Steve. I will follow your steps exactly and see what happens. Thanks for the help, and I will post back here later this evening or tomorrow and let you know what happens. Thanks!

If your goal is to dual boot, i might not be able to help you.  If you're trying to just set up a bare-metal crux system, your grub install process must be wonky, though, all I do is:

(appropriate fstab changes)

grub-install /dev/sda

(compile kernel, make modules_install, make firmware_install, cp System.map /boot/, cp arch/x86/boot/bzimage /boot/vmlinuz-1)

grub-mkconfig > /boot/grub/grub.cfg

reboot

I don't think I'm missing anything critical there as far as just being able to boot is concerned...

I am using grub in Ubuntu because when I install grub in CRUX, I reboot to a grub rescue prompt and not a grub menu. It is very inconvenient. The UUID in stab just takes the place of where you put /dev/sdb, etc. Does that help clear it up? Thanks

How or more importantly why are you using Ubuntu's grub2 in crux?

Is it an EFI system?  I'm not sure what you mean by UUID in the context of fstab, I almost always have something like:

/dev/sdb1   /    ext4   defaults,noatime(or whatever)   0   1

I wouldn't recommend using utilities for a different distrobution, crux comes with grub2.

I am trying to boot from the Grub that comes standard with an Ubuntu installation. I am installing on bare metal. I did compile my root filesystem into the kernel. I am using ext4. I did setup fstab with the uuid of the CRUX partition. Sorry for the confusion.

I have a few questions, but first, what is "ubuntu grub2"?  Are you installing on a VM or bare metal?

Did you compile your root file system into your kernel?  What file system are you using on your root file system?  Did you set up fstab?

Everytime I try to boot CRUX from Ubuntu's Grub2 it fails with a kernel panic.

It gives me the error message, " unable to mount root filesystem on unknown block (0,0)".

Can someone help me with this? Thanks!
