I'm now asking this in order to be able to answer my other questions better and to understand more.
I want to know what it is like when a hard drive is installed in a laptop. Does any hard drive fit and is there a Windows directly on it or what is this install (not the word) so you have to install something on it?
How is it all
Then I can also learn something about it.
The hard disk must fit from the connection. Old disks use the IDE / PATA interface, newer disks and SSDs use the SATA interface.
The plates must be initialized and divided before operation. Then you can install Windows. The setup does all of these steps automatically.
Attend a course on building and operating a PC. Something like that is explained.
There will be no courses here because the topic is too complex.
SATA SSDs with 2.5 or sometimes 3.5 inches usually fit into a laptop. Windows must be reinstalled and activated with the activation key. To do this, you need to create a USB stick with Windows.
If you want to have a Linux distribution, it must also be installed on the hard disk. So it is not absolutely necessary to have MS Windows on the laptop. Linux distributions (Distris) are free (except for Red Hat and Suse Enterprise)
SSDs and HDDs in 2.5 "size fit in laptops, note height. Newer models also have M.2. Interfaces for SSDs. For example https://geizhals.de/...at&hloc=de
Operating systems must first be installed on new HDDs, SSDs, whether Windows, Linux or any other.
Some small laptops also have 64GB soldered flash drives.
1) No, not every hard drive fits.
2) No, there's usually no Windows preinstalled on an extra hard drive.
You have to pay attention to a suitable hard drive when buying (it is different for each laptop, which fits in there. You have to look in the data sheet. Often it is 2.5 "SATA disks) and the operating system (e.g. Windows) must be installed via an installation medium ( e.g. An installation USB stick, you can create yourself).
What do you mean by "initializing and dividing up before operation"?
Must be divided into sections before operation.
