That was a very informative link. Unfortunately, it did not work for me. I still come up to the grub> prompt. I do not get a splash screen from which to choose even the GRUB2 Chainloader. It simply comes up with the grub> prompt. I then only have the option of going through Steps 1 - 4 which brings me to a login prompt. I can login as root and issue the startx command, and I am back in the 3 window mode with Hwclock. I must be missing something somewhere, but I have no idea what.

I thought I had, but anyway, here it is:

I found your mistake:

I have a hunch you're following the Install guide which treats HDD's as SCSI Devices, i.e. sdX, and you are using the DEPRECATED option treating them as hdX. Grub 2 won't work properly, at least in any documentation I've seen, using hdX, and using grub1 you have written your grub.conf using sda instead of hda, like the handbook. See below for that fix

Please:

This is what I have so far:

Run genkernel --menuconfig all --splash etc whatever other options you use. Check the filesystems section for ext4 support as an *, and then rebuild it, regardless if you update anything as make clean before menuconfig wipes out the modules.

Ext4 support was already selected as built-in. It is compiling 3.10.7-gentoo-r1 bzImage... . I'm guessing that it may take quite a while as it states in the handbook.

Kernel compiled successfully.

Edit: went through the handbook as best as I could, rebooted and had to login as root and run startx. Now I am back at the 3 xterm windows.

Further update in progress. I went through the grub prompt doing Steps 1 - 4 posted earlier, added minizip to my USE flag, and added a video statement which changed screen resolution through the boot process to that supported by my wide screen monitor. Then following some steps in one of my other threads in attempting to regain my KDE gui, I kicked off:

Did you still want Grub:2 :?:

Yes, I think so since that is the way it will be for the foreseeable future. But I am pretty sure that I still have it on my system. I don't really have any problem with it as long as I won't have to keep going through those steps just to get out of the grub> prompt before I can start using the computer. Kind of takes a little fun out of it, wouldn't you think?

In a little while, I will break for lunch and I expect the KDE install to be complete. I hope I can then reboot into a normal desktop environment.

Well, that didn't do much in the way of helping to get back to where I wanted to be. I removed grub:2 and installed grub:0, so it now comes up to that grub> prompt, but the commands are a bit different and I didn't have much time on my lunch break to delve into that to get it to even load the kernel. Got to do some more reading.

Edit:
Followed instructions in the GNU GRUB Manual 0.97 and it will not boot. No available partitions, Kernel panic - not syncing: VFS: unable to mount root fs on unknown-block (0,0), and it all stops right there. This is what it was doing before. I think I am about reach to scrap this and start all over.

Surprise. Turned machine off and back on, and this time I got a splash screen allowing me to choose what to boot. I chose the chainloader and got to a prompt. Still had to login and run startx and have gotten back to the 3 xterm windows. Wonder what will happen if I emerge grub:2 this time?

Sorry, it was a root prompt, not grub. So grub 0.97 is working.

Rebooted once more at lunch break and chose the Gentoo Linux 3.10.7-r1 this time. It still comes up to the same end result. So I still have more homework to do to figure out how to boot into my gui.

I did think that I could remove grub 2 with:

So each time you boot, you get to the login prompt Correct :?:

Can you run your Chosen GUI with startx :?:

What is your chosen GUI :?:

Your done with grub... Now we will setup the X Server, then add KDE, then emerge Grub:2, test the chainloader, then actuall install grub 2

Are you logged in as root
Have you configured XOrg already
Have you emerged kde-meta
