[xubuntu-users] Grub problems

[Phil]

Thank you for reading this.

I managed to install 14.04 from the mini.iso but the boot loader was 
installed on the USB stick instead of the internal drive. The internal 
drive is SDB and the USB stick is SDA. During the installation process 
the boot loader is installed on SDA and I don't recall that a choice as 
given.

Anyway, I attempted to install grub on the internal drive and now when 
the system boots I'm left with a command line prompt like this "grub>". 
Entering "boot" returns an error message something like "you need to 
load the kernel first".

Boot-repair looks like the answer but I don't have a working CD drive 
which is why I had to mess around with a USB stick in the first place.

It's been a long day, can anyone offer any help?
