I thought you have installed Linux on a separate SSD ?

but still even on the same SSD your windows partitions would not be visible by default unless you mount them.

All your drives mentioned won't be usable in Linux unless they are mounted. 

About separating it from Windows it's confusing what you mean by that ?

I created an install dvd from the Ubuntu iso file. The install created a new partition and put Linux on the same SSD drive as windows. There was no other option as far as I can see. The partition is 11GB.

Windows thinks it's a new empty drive.

In Linux I can read and see everything on the PC. All 5 disks That's what worries me. I'm not sure what mounting means? I think all my drives are already mounted?  And I'm not sure why it says I have 1TB of space? At least that's what I think it says?

I don't want it having access to anything but my empty external drive? Is there an equivalent of file explorer?

linux has a file called etc/fstab. filesystem is fairly different (and a lot more advanced than windows)

There are also a lot more options, which although a bit daunting at first will leave you feeling like you are in the 90s once you get the hang of it and return to the C, D E F G H I J K L M N O P Z windows drives.....

Typically you have physical disks and logical disks - physical are the actual drives themselves, a logical disk lets you configure multiple physical disks (made up of partitions on physical disks) so they appear as one big drive to the OS (which can be grown by adding new disks).

Mounting is the software equivalent of plugging one of these into the machine, the /etc/fstab file configures how they are mounted when you switch the machine on, the installer probably configured all your existing disks for you.

If you want to hide them you can either (as a super user/sudo)

use umount command to unplug them (good till the next time you start the machine)

use whatever disk gui ubuntu has to change the configuration

stick a # at the beginning of the relevant line that automatically mounts it in /etc/fstab to comment it out.

this is my /etc/fstab

[msparks@localhost ~]$ cat /etc/fstab

That's 1x 1TB SSD which has 4 logical disks (2 with the btrfs filesystem, one with ext4 and one with vfat) for various OS stuff, /home is the equivalent of /Users/ on windows.

and a 256GB NVME mounted in /home/msparks/nvme

That is fine using Linux on the same SSD , it shouldn't be a problem

Hmm do you mean to say when you open the file explorer you can see the windows and the other drivers ? By default they are never mounted.

for Linux the File explorer is Nautilus / Dolphin / Thunar , Ubuntu probably is using Nautilus, it's that third icon that looks like a folder.

Probably you are not reading that drive number correct and thinking it's showing as 1TB , or it's probably showing the external usb.

Linux will not do anything to your other drives.

On Ubuntu, could you run your system monitor and show a screenshot of the file systems tab?. With your description, I don't really understand where your Ubuntu is installed.

It's normal that Windows doesn't see the main Linux partition, it doesn't know it's file system (probably ext4).

That should not worry you. Linux won't do anything bad to your Windows partitions, unless you do it yourself and erase some random things. Contrary to what HumptyDumpty said, Ubuntu shows your NTFS (Windows) partitions by default, and mounts them if you click on their icon.

"Mounting" just means making the filesystem accessible, and writeable if the partition is not read-only.

The purpose is to get greatly increased performance running X-Plane.

FYI, you won't get "greatly increased" performance. You will get better performance. People tend to exaggerate. 🙂

That's what I said , they will be visible when mounted or when set in fstab , else they won't be visible as a mounted disk.  

He has Ubuntu installed alongside windows on the same drive, that's what I feel.

for better info he should run "disks" that would show much more info. 
 

I think he is confused because in Nautilus one would see the drives , so he thinks that those are already accessible , but in truth they won't be unless mounted.

I've done it! After much fuss and bother Linux is now on the USB drive but the PC boots straight to Windows unless I press F11. 
 

Now for X-Plane. Where can I find my licence key?

Second this, I am still unable to see how a different operating system can make performance better. It is literally the same machine code. The only potential performance difference might be caused by graphics driver implementations, which is again not about the operating system.

lol , the pc should have a boot option like f12 or something where you can select the device to boot from.

Your license will be in your email I suppose when you purchase XP

One thing , they might lock your license if they find a different system ID , it has happened to me twice but then they resolved it once i told them i am using a dual boot system and XP runs on both.

Well with Linux i can say as a server system or even for my laptop it runs much snappier , can't say that it will be better in gaming , the reason for the snappier feel is because Linux was never meant to power save being a server oriented OS hence it runs things full fledged, where the windows desktop is more power conscious .

Same machine code ? Certainly not (or maybe I misunderstand what you mean by "machine code"). Each OS has his own code for hardware access, memory managment, disk access,... And there are thousands reasons the performance can be different on different OSs.

As I said, X-Plane's performance is usually better on Linux, at least in my case. But not "jawdropingly better". 🙂

Yup. But I can't find it. I'll contact LR and see what they say....

On my PC it's F11 but if you don't press it it boots to Windows which is ideal. So Linux has 1TB of independent space.

Not even close. Windows, at its heart, is still the same Windows NT kernel released in 1993.

Linux has had every computer science department of every university put decades of research into making sure every syscall runs as efficiently as possible.

Most recently these guys:

The gap between them now is really obvious, even if you limit it to the really obvious things like the difference between BTRFS and NTFS performance
