Can you boot into Kubuntu using chemicalfan's method .. then post the contents of

What happens if you use the boot device selection key (F8 was it ?) and select the 500GB HDD ?

That's how I've been booting into Kubuntu other than doing it the way chemicalfan explains how to boot.
It lists my Hd's, CD/DVD drive and HP Printer USB port (where I can plug in the USB Multiboot)

OK, I'm gonna guess that the boot order has changed in the BIOS, probably back to /dev/sda

So we have 2 options

a) firure out why it won't let you into the BIOS by hitting the "Del" key

or

b) write GRUB stage 1 to the MBR of sda

Try to get into the BIOS .. if you still can't by tomorrow, I'll tell you how to bung GRUB on sda, and point it at the Kubuntu installation.

But I'm off to bed for tonight :)

So have you managed to get into the BIOS by shutting down (not reboot) your PC .. then turning it ON, and as soon as you see the POST (Power On Self Test) screen or the manufacturer logo, hitting the "Del" key ?

Nope!
I have noticed this from last night

Some things weren't done!

I have also been onto the ASUS web site and downloaded my current BIOS (2002) and the new BIOS (2102) - Which only came out 2 months after the 2002 BIOS.
But I cant seem to download the program to install it

Shutting down didn't work.
I've tried [F8] Boot selection and tried all HD's but only SDC (500Gb) boots.
I think the BIOS has crashed and I need to recover it but as I mentioned in my last post, I cant seem to download the installer!

The BIOS cannot be corrupt, or your PC wouldn't boot ;)

What I think is happening is that the boot order changed (probably back to sda) but this isn't important if it's always going to be there .. we can tell GRUB to install to the sda MBR, but point to Kubuntu on sdc1.

The only way to be 100% sure is to access the BIOS .. and this would be easier .. but installing GRUB to the MBR of sda won't hurt anything (you'll still be able to boot how you are now), it just might not work.

You could try resetting the BIOS back to defaults with the jumper on the motherboard .. do you know how to do that ?
(don't do it yet)

Have you tried a different keyboard ? .. preferably a PS/2 keyboard to access the BIOS ?

I haven't got a PS/2 Kbd, only USB wired & wireless. I have got a USB to PS/2 adapter tho' lol
I have known about resetting the BIOS but not sure where the jumpers are, are they near the battery?

Only the purple USB --> PS/2 adapters work for keyboards .. the green ones are for mice.

The BIOS reset jumper is USUALLY next to the battery .. but probably best to get the motherboard manual:

OK, would not be easier to swap sda and sdc (might have to adjust fstab though might not required as using UUID),
boot to Kubuntu run update-grub and see where you get with that.

Sorry I've been AWOL, been a busy 24 hours...

Glad you got it working :)
Out of interest, what's the default option in the GRUB menu now? I suspect you're using the GRUB that's on sda, unless you changed the boot order in the now-working BIOS? Anyway, many ways to skin this cat, glad it's working now.

Incidentally, it's worth playing with Manjaro in a VM (such a Virtualbox) before plumping for an installation on hardware. It's good practice, as it allows you to get familiar with an OS without risk of damaging everything. You can snapshot it so if the OS does break, you can roll back easily, plus you can keep a browser window open in the host OS while working in the terminal (outside of X) in the guest. VMs are awesome :D
