Will not boot from SSD, just USB drive. Custom system

[selfDistruct]

Ok guys, I was using the IRC channel witch was loads of help. But this last part seams to be having some issues getting done. So im going to explain a little and see what I get. I appreciate your patience as i know enough to know i know very little, which is why im here

Pc:

Gigabyte GA-K8N-SLI
1 gb ram
AMD Athlon(tm) 64 X2 Dual Core Processor 3800+ × 2
gforce 7800 gtx
ocz ssd agility 3 120gb (brand new SSD, no files installed before this.)

The issue is i have used the USB boot method, im on it now. connects fine, runs great.. off the USB drive. it will not boot from SSD, i have checked the bios list settings made changes to the order, but still nothing. Uninstalled and reinstalled ubuntu though the USB. When i attempt to boot from SSD it gives me a DMI verifying hang issue. The system sees the ssd, knows the size, i see ubuntu's files in it. edit,save, no issues. But it will not boot.

This is an old system built by my late father, 5 plus years old. I have no other hdd to use other then this one ssd. Any help would be greatly appreciated.

As i said i know relativly little, so bear with me!

Thanks in advance!

After searching I have found

I will post suggested commands. And quotes in the thread.

oldfred ""When you install Ubuntu with the auto install options, the grub2 boot loader is normally installed to sda. Some computers make the flash drive sda by default so you may have installed grub to the flash drive."""=

sudo fdisk -l

When i use sudo grub-install /dev/sda or sdb

ubuntu@ubuntu:~$ sudo grub-install /dev/sda
/usr/sbin/grub-probe: error: cannot find a device for /boot/grub (is /dev mounted?).
ubuntu@ubuntu:~$ sudo grub-install /dev/sdb

I enter in this...

sudo debconf-show grub-pc

Any thing would help. Thanks,

Did you unmount the devices?

WARNING! Caution, don't try on production machines without fear of dealing with problems.

Launch the Linux Live USB flash drive (created with e.g. UNetbootin) & open the Terminal:

sudo fdisk -l
sudo mount /dev/sdaX /mnt

(e.g. sudo mount /dev/sda1 /mnt)

sudo grub-install --root-directory=/mnt /dev/sda
sudo umount /mnt
sudo update-grub
sudo reboot

Ok fallowed. But still getting that mount issue. They only place i know to unmount other then what you just showed me is in Disk Utility tool.

sudo mount /dev/sda1 /mnt
sudo grub-install --root-directory=/mnt /dev/sda
Installation finished. No error reported.

sudo grub-install --root-directory=/mnt /dev/sda
Installation finished. No error reported.


sudo umount /mnt
umount: /mnt: not mounted

sudo update-grub
/usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?).


Thanks alot for the help.
