Installing New OS directly

[towerdefence661]

Wanting to know, is their a possible way to download Rasperian directly using the raspberry pi’s internet explorer, directly onto the files and then somehow installing that as the OS, replacing NOOBS OS.
What I’m asking for is a way to install a new OS without the use of an external device like a computer.

You can download a new OS image and write it to a new card, but you can't overwrite the card you are running from.

Not disagreeing with the reply from @rpdom, but expressing it in different terms...

You cannot (well, not with your level of knowledge and experience) perform an upgrade that 'slides' a new Operating System installation underneath your current running system.

But if you have an RPi that is already running an OS such as Raspbian you can use that as a workstation to install a fresh version of Raspbian onto another microSD card and then shut down, swap cards, and reboot into the new OS. You will need a usb microSD card reader - the built-in card slot is already in active use by the running Operating System.

(This is all based on the standard default model of booting from a microSD card. Other options present themselves if you use the ability of recent RPi models to boot from Mass Storage or the network.)

The upshot is that you can make progress without needing an additional 'external' computer. But you can't do it 'directly.'

Microsofts Internet Explorer Browser does not run on Raspbian, the de-facto browser is chromium-browser.

Maybe PiNN which is an advanced version of NoobS will be able to undertake what you require ??

i just play with this idea:
+ using a RPI3 booting USB stick
( if you want: RPI3 need usb boot enable OTP / raspbian desktop sd card copier tools copy SD to USB stick / power off / remove SD card / power on )
+ use a old SD card ( in USB card reader or here in card holder of RPI hot plug )
+ use gparted to clean and new partition and reformat FAT32
+ download and unzip PINN lite
+ reboot from SD card and install any OS from that long list by download via internet.
details here

required hardware
+ RPI ( here used 3B)
+ USB stick
+ SD card
+ power supply
( a LAN PC ( here win7 / putty / real VNC ) for headless operation ) OR
+ HDMI TV / keyboard mouse

the required software RASPBIAN desktop +
sudo apt install -y gparted mc

Since NOOBs is really only classed as an "OS installer", I'm not clear if by "NOOBS OS" you mean you want to remove NOOBS and write a new OS directly to the card, or whether you just want to replace the OS that you already installed with NOOBS?

One of the benefits of using NOOBS is that it allows you to do exactly what you are asking, i.e. to install OSes on your SD card without having to use an external computer. NOOBS is capable of installing the latest version of Raspbian over the internet and replacing the OS already installed. So why do you want to change away from a working solution that is probably the easiest for you to achieve given you already have NOOBS installed? There are several other ways to achieve what you want that may remove any objections you have to using NOOBS. So to provide an optimal answer for you, you need to provide some additional information:

1. Are you using NOOBS or NOOBS-lite?
2. Which version of NOOBS have you got installed?
3. Which OS have you got installed that you want to replace?
4. What OS do you want to install (Raspbian)?
5. Why do you want to remove NOOBS?
6. Why do you want to install an OS directly instead of through NOOBS?
7. What size SD card are you using?
8. Which model of RPi are you using?
