7.18. Disk Partitioning Setup

Warning

It is always a good idea to back up any data that you have on your systems. For example, if you are upgrading or creating a dual-boot system, you should back up any data you wish to keep on your drive(s). Mistakes do happen and can result in the loss of all your data.

Installing in text mode

If you install Fedora in text mode, you can only use the default partitioning schemes described in this section. Therefore, although you can choose to use a whole drive, to remove existing Linux partitions, or to use the free space on the drive, you cannot customize the partition layout. That is, you cannot add or remove partitions or file systems beyond those that the installer automatically adds or removes. If you require a customized layout at installation time, you should perform a graphical installation over a VNC connection or a kickstart installation.
Furthermore, advanced options such as LVM, encrypted filesystems, and resizable filesystems are available only in graphical mode and kickstart.

Important — Booting from RAIDs

If you have a RAID card, be aware that some BIOSes do not support booting from the RAID card. In cases such as these, the /boot/ partition must be created on a partition outside of the RAID array, such as on a separate hard drive. An internal hard drive is necessary to use for partition creation with problematic RAID cards.
A /boot/ partition is also necessary for software RAID setups.
If you have chosen to automatically partition your system, you should select Review and manually edit your /boot/ partition.
Partitioning allows you to divide your hard drive into isolated sections, where each section behaves as its own hard drive. Partitioning is particularly useful if you run multiple operating systems. If you are not sure how you want your system to be partitioned, read Appendix A, An Introduction to Disk Partitions for more information.
Disk Partitioning Setup
Choose automatic partitioning or manual partitioning.
Figure 7.25. Disk Partitioning Setup

On this screen you can choose to create the default partition layout in one of four different ways, or choose to partition storage devices manually to create a custom layout.
The first four options allow you to perform an automated installation without having to partition your storage devices yourself. If you do not feel comfortable with partitioning your system, choose one of these options and let the installation program partition the storage devices for you. Depending on the option that you choose, you can still control what data (if any) is removed from the system.
Your options are:
Use All Space
Select this option to remove all partitions on your hard drives (this includes partitions created by other operating systems such as Windows VFAT or NTFS partitions).

Warning

If you select this option, all data on the selected hard drive(s) is removed by the installation program. Do not select this option if you have information that you want to keep on the hard drive(s) where you are installing Fedora.
Replace Existing Linux System(s)
Select this option to remove only partitions created by a previous Linux installation. This does not remove other partitions you may have on your hard drives (such as VFAT or FAT32 partitions).
Shrink Current System
Select this option to resize your current data and partitions manually and install a default Red Hat Enterprise Linux layout in the space that is freed.

Warning

If you shrink partitions on which other operating systems are installed, you might not be able to use those operating systems. Although this partitioning option does not destroy data, operating systems typically require some free space in their partitions. Before you resize a partition that holds an operating system that you might want to use again, find out how much space you need to leave free.
Use Free Space
Select this option to retain your current data and partitions and install Fedora in the unused space available on the storage drives. Ensure that there is sufficient space available on the storage drives before you select this option — refer to Section 4.4, “Do You Have Enough Disk Space?”.
Create Custom Layout
Select this option to partition storage devices manually and create customized layouts. Refer to Section 7.20, “ Creating a Custom Layout or Modifying the Default Layout ”
Choose your preferred partitioning method by clicking the radio button to the left of its description in the dialog box.
Select Encrypt system to encrypt all partitions except the /boot partition. Refer to Appendix C, Disk Encryption for information on encryption.
To review and make any necessary changes to the partitions created by automatic partitioning, select the Review option. After selecting Review and clicking Next to move forward, the partitions created for you by anaconda appear. You can make modifications to these partitions if they do not meet your needs.
Click Next once you have made your selections to proceed.
