Is this correct so far?

I've never used archboot, but does that look correct to you?

Output of gdisk -l? ls /boot? ls /boot/grub? Does /boot/efi exist? (It shouldn't.)

Well I have my system setup to a fully functional system, although I still can not boot under boot here is what I have

/boot/grub
/boot/lost+found
/boot/initramfs-linux.img
/boot/initramfs-linux-fallback.img
/boot/vmlinuz-linux

here is grub.cfg

I'm not sure... Your grub.cfg doesn't look right to me but I'm booting in EFI mode and you're using BIOS. (I never managed to boot a gpt disk in bios mode - probably a firmware bug on this machine.)

How did you generate grub.cfg? You didn't give contents of /boot/grub/ - is that where your grub.cfg is?

When you say that you cannot boot under boot, do you mean that you can boot and chroot into the system using a usb boot disk such as supergrub but that you cannot boot from the internal drive? Or do you mean you can boot but you get, say, a grub prompt and have to point it to grub.cfg or whatever manually?

I'd guess you need to correct the error noted above for things to work.

@cfr: Thats a combo of grub-mkconfig and Archboot setup script generated grub.cfg .

mich04 · 2012-02-12 20:36:42

Arch boot comes with the option of installing grub-2 bios or uefi as the boot loader, so I had archboot install it. /boot/grub is fully populated it looks like there are a lot of files. that is also where my grub.cfg file is located.

When I boot my system it does not bring me to any screen where I can tweak the options just a black screen with the words grub and a blinking dash.

When I use the supergrub2 bootdisk it gives me the option of searching for any grub.cfg files it finds one at I believe hda1,gtp I select the one that iot finds and than my system is able to boot normally. So I do not chroot into the machine it finds the grub.cfg file than boots normally bringing me to the screen where I select my os (arch or arch fall back).

Ah, OK. Thanks. So it doesn't then need the /boot/vmlinux-linux but only /vmlinux-linux?

And is the OP's error about not finding anything under /tmp/install/ expected in this case? I tend to think if I see an error of that sort I should stop and figure it out because anything later will assume that step succeeded, but perhaps that's just because I don't know when something is safe to ignore!

mich04 · 2012-02-15 13:34:55

/tmp/install/

That is the directory that Archboot makes during installation

/mnt/arch

That is the directory that Arch net install makes. at least that is what I concluded. That grub file, and configuration was made by Archboot. Archboot is the current installation method I am working with. So I believe that /tmp/install would apply. At the moment though I have a great fully functional desktop running compiz, lxpanel, pcmanfm, and all of that jazz. so if there is a method of re installing grub or fixing it from the desktop it is an option now.

OK. But

Couldn't find
/tmp/install/usr/lib/grub/i386-pc/kernel

looks like it couldn't find something there. I'd guess you need to fix that error.

ok, so I took apart my computer because I needed to replace the power supply. I cleaned it with air and put it back together and now the computer starts up fine without grub errors. I did go from a 80 watt psu to a 120 pico....I don't understand...but it works now.
