This is the step which can result in data losses if the settings are not what you intended.
the 2nd option starts the cfdisk partitioner and is for those users who know what they are doing with this
Enter the size of your SWAP partition. For low-RAM computers a SWAP with twice as much MB
as the RAM is often a good choice. More than 500 MB
is not necessary as long as you run no extremely memory-consuming applications.
The actual installation
You see the name of the currently treated package.
Sit back and relax, it is working. This will take a while depending on your computer.
On 586 CPU and according disk and RAM, it should be done in –let's say– 45 minutes.
Language, keyboard and passwords
Select the keymap for your keyboard. You select the country and the installer tries to find the keymap usually used in this country. That means, if you are living in the USA but using a German keymap for any reason, German must be your choice.
choose the harddisk where you want the GRUB. The installer writes the data automatically into the MBR (Master Boot Record) of this harddisk and overwrites the previous content without saving it. So be careful, if you wanted a dual boot system.
If you're installing only one operating system, you should most likely pick the root partition, the one without a number like /dev/sda.
