<p>Model is ASUS F505ZA-DH51</p>
<p>Thanks much Paul!</p>
<p>I have followed a disassembly youtube vid and yes, it requires
removing the keyboard by removing all the screws from the bottom
and running a guitar pick under the surface of the top edge and
then the keyboard is removable. I carefully lift and tip the
keyboard out, leaving the connectors. Then the mother board is
accessible and the show me guy swaps out drives. Where he has a
drive, I do not. It's not there. The expansion bay for a 2.5"
drive is visible but it's upside down. I had cloned the onboard
drive to a 500GB SSD and was able to gently get it, upside down,
into the bay and plugged in. It shows up as a bootable drive in
the BIOS. But the UUID problem causes the onboard drive to boot
regardless of my setting the boot order (which I can discern by
the size of the partitions). Obviously the default as it doesn't
matter how I set the boot order, I can't boot the expansion bay
drive. Obviously the machine wants to boot the factory drive. I
think changing the UUID is possibly best.<br>

<div>Do you have a model number for the laptop? If you provide
it, we might find some disassembly guides. <br>

<div>Have you tried removing the keyboard to see if you have
access to the ssd that way? I know some Asus models did that
at one point. I hate how difficult laptops have gotten to work
on. I love my Thinkpad t480. It's nice and easy to work on.
But it's getting a bit long in the tooth, and accessible
hardware is definitely the exception and not the rule these
days.</div>

<p>Thanks Paul</p>
<p>That seems pretty simple. Still wonder why the
motherboard is in upside down and screws not accessible to
lift it out. Weird.</p>
<p>I actually cloned one drive to another, larger drive.
I've done this many times and would just take out the old
drive and install the cloned drive. I did this as I
required more data storage. However, I can't remove the
factory drive as it's not accessible. If I could I would
do what I said. Clone the computer's drive to a larger
drive, swap them out and boot happily away with the larger
drive. Changing the UUID made sense but I didn't know how
to do that.<br>

<div>It sounds like you may have cloned one
partition to the other? This would explain them
having the same uuid. You need to change the uuid
of one of the partitions. <br>
<br>
</div>
Let's say you want to change the uuid of /dev/sdb1.
Make sure the partition is not mounted, then use:<br>
<br>
`sudo tune2fs -U random /dev/sdb1`<br>
<br>
</div>
That should do it. <br>
<br>
</div>
This is untested on my part, so please do all the
necessary backing up, etc. before trying. </div>

<p>Hello All</p>
<p>I'm revisiting an issue I expressed many months
(if not years. I have an ASUS laptop in which I
wanted to install a 500GB SSD in the vacant bay. I
said at the time that the motherboard is up side

and replace with the 500GB SSD drive. I was able
to get the regular SSD into the bay and plug it
in. It shows up in the BIOS as two separate
UUIDs (I have a bootable 313 GB partition and a
free space 193 GB partition. When I choose to
try and boot the 313 GB partition the computer
reverts to the drive stick. I checked the UUIs
and the 313GB has a different UUID than the
internal stick drive but the same as the 193
SSD. So for some reason, even though I change
the boot order so the 313GB boots, the computer
reverts to the onboard UUID and boots that. I
don't know how the 193 GB drive got the same
UUID but it did.</span></p>

the unbootable 313GB drive which won't boot). I
would then upgrade the 313 GB drive after
cloning the onboard drive. If the cloned 313GB
drive updated then I would have my current
mountains of data on the 313GB drive. But if it
won't boot now why would it boot later, after
all of the work?</span></p>
