Optional: Set NTP serverIf you have a working internet connection, you can use a NTP server. A NTP server is used for time synchronization. You can choose the Run as daemon option if you want your time to be synchronized on every boot. The time will automatically be synchronized after clicking Accept.

Step 3: Setting up your diskA suggested partition scheme for your hard disk is shown. If you have another operating system installed on the same hard disk (for example, Microsoft Windows or another Linux), YaST will resize that operating system so that it still on your computer, but has enough room to install openSUSE. Here you can see that the partitions are already created and the system proposes to format only the root (/) partition. If you are not happy about the proposed configuration, you can click Create partition setup. If you use Edit partiton setup the partitioning program is loaded, showing you the proposed configuration, which you can edit manually. If you want to learn more on custom partitioning, please read SDB:Partitioning.

Step 4: Create the primary userEnter your full name, an username will be automatically chosen. If you wish you can change this username to your liking. Specify a new password twice, for verification. By default, the system is set to use this password for the system administrator (also known as root). Also, automatic login is turned on by default. However, if you wish to have a more secure system and/or multiple users, uncheck this options. YaST makes a check if your new set password is secure enough. You will get prompted if it is to insecure. You can then choose to change your password or to continue and ignore this warning.

Note on installation to large partitions
Many users will be upgrading from previous dual boot windows-linux distributions. YaST will detect empty ext3 partitions, say on a second hard disk and offer to convert them to ext4. For example if there are two empty ext3 partitions it will create an root ext4 partition and data ext4 partition, with the larger partition being assigned to data (/home) by default. On modern systems the scary warning in the Boot section just before commitment during installation, that GRUB will place the bootloader above 125 GBytes and the user is risking that the bootloader will not be found can be disregarded (of course with a certain risk). A check is possible before commitment if you cancel the install at this stage before you lose a useful MBR. Without a valid MBR a disk will not be accessible anymore and steps must be taken to recover all the data on that disk You can do this in an old linux distro that uses GRUB by copying your old linux root partition to the partition that you will use, and adding a new entry to GRUB menu.lst with as root partition this test root partition. If a boot test goes well you can then delete the contents of the temporary test root partition and the SUSE installer may well use it as its default root ext4 partition.
