Partitioning

Suggested Partitioning

In this screen you can see + the content of your hard drive(s) along with the DrakX partitioning + proposals for where to install Mageia.

The actual options + available from those shown below will vary according to the layout and + content of your particular hard drive(s).

Main Options

Use Existing Partitions
If this option is + available, then existing Linux compatible partitions have been found and + may be used for the installation.
Use Free Space
If you have unused + space on your hard drive then this option will use it for your new + Mageia installation.
Use Free Space on a Windows Partition
If you have unused + space on an existing Windows partition, the installer may offer to use + it. This can be a useful way of making room for your new Mageia + installation, but is a risky operation so you should make sure you have + backed up all important files!
With this option, the installer displays the remaining Windows + partition in light blue and the proposed Mageia partition in dark blue + with their intended sizes just underneath. You have the option to modify + these sizes by clicking and dragging the gap between both partitions. + See the following screenshot:
Erase and use Entire Disk
This option will + allocate the entire drive for Mageia
Warning
This will erase ALL + data on the selected hard drive. Take care! If you intend to use part + of the disk for something else, or you already have data on the drive + that you are not prepared to lose, then do not use this option.
Important
Note that this + involves shrinking the size of the Windows partition. The partition + must be "clean", meaning that Windows must have closed down correctly + the last time it was used. It must also have been defragmented, + although this is not a guarantee that all files in the partition have + been moved out of the area that is about to be used. It is highly + recommended to back up your personal files.
Custom Disk Partitioning
This gives you + complete control over the placing of the installation on your hard + drive(s).

If you are not using the Custom disk partitioning + option, then the installer will allocate the available space according to + the following rules:

If the total available space is less than 50 GB, then only one + partition is created. This will be the / (root) + partition.
If the total available space is greater than 50 GB, then three + partitions are created
- 6/19 of the total available place is allocated to + / with a maximum of 50 GB
- 1/19 is allocated to swap with a maximum + of 4 GB
- the rest (at least 12/19) is allocated to + /home

This means that from 160 GB or greater available space, the installer + will create three partitions:

50 GB for /
4 GB for swap
and the remainder for /home

Note

If you are using a UEFI system, the ESP (EFI System Partition) will + be automatically detected - or created if it does not exist yet - and + mounted on /boot/EFI. The Custom disk + partitioning option is the only one that allows to check it has + been correctly done.

If you are using a Legacy (also known as BIOS) system with a GPT + partitioned disk, you need to create a BIOS boot partition if it doesn't + already exist. It should be about 1 MiB with no mount point. It can be + created with the Installer, under Custom disk + partitioning, like any other partition. Be sure to select + “BIOS boot partition” for filesystem type.

See DiskDrake for information on how to + proceed.

Important

Some newer drives are now using 4096 byte logical sectors, instead + of the previous standard of 512. Due to lack of available hardware, the + partitioning tool used in the installer has not been tested with such a + drive.

Some SSD devices now use an erase block size over 1 MB. If you have + such a device we suggest that you partition the drive in advance, using an + alternative partitioning tool like gparted, and to use the following + settings:

Align to = MiB
Free space preceding (MiB) = 2

Also make sure all partitions are created using an even number of + megabytes.

Choose the mount points

Here you see the Linux partitions that have been found on your + computer. If you don't agree with the DrakX suggestions, you can change the + mount points yourself.

To the left of the drop-down menus is a list of available + partitions. For example: sda is a hard drive - and + 5 is a partition number, + followed by the (capacity, mount point, filesystem + type) of the partition.
If you have several partitions, you can choose various different + mount points from the drop down menu, such as + /, /home and + /var. You can even make your own mount points, for + instance /video for a partition where you want to + store your films, or perhaps /Data for all your + data files.
For any partitions that you don't need to make use of, you can + leave the mount point field blank.

Warning

If you make any changes here, ensure you still have a + / (root) partition.

Tip

If you are not sure what to choose, click + Previous to go back and then tick Custom + disk partitioning, where you can click on a partition to see + its type and size.

If you are sure the mount points are correct, click on + Next, and choose whether you only want to format the + partition suggested by DrakX, or more.

Confirm hard disk to be + formatted

Click on + Previous if you are at all unsure about your + choice.
Click on + Next to proceed if you are sure that it is OK to + erase every partition, every operating system and all data that might be on that hard disk.

Custom Disk Partitioning with + DiskDrake

Modify the layout of your + disk(s) here. You can remove or create partitions, change the filesystem + or size of a partition and even view their details before you + start.
There is a tab at the top for + every detected hard disk (or other storage device, like a USB key). In + the screenshot above there are two available devices: sda +and sdb.
For all other actions: click + on the desired partition first. Then view it, or choose a filesystem and + a mount point, resize it or wipe it. Expert mode + provides more options such as to label (name) a partition, or to choose + a partition type.
Continue until you have + adjusted everything to your satisfaction, then click + Done when you're ready.

Warning

Take care with the + Clear all option, use it only if you are sure you + want to wipe all partitions on the selected storage device.
If you wish to use + encryption on your / partition you must ensure + that you have a separate /boot partition. The + encryption option for the /boot partition must + NOT be set, otherwise your system will be unbootable.

Important

If you are installing Mageia on a UEFI system, check that an ESP + (EFI System Partition) is present and correctly mounted on + /boot/EFI. See Figure 1 below.
If you are installing Mageia on a Legacy/GPT system, check that + a BIOS boot partition is present and of the correct type. See Figure 2 + below.

Figure 1. EFI System Partition

Figure 2. BIOS boot partition

Formatting

Here you can choose which + partition(s) you wish to format. Any data on partitions + not marked for formatting will be preserved.

Usually, at least the + partitions that DrakX selected need to be formatted.

Click on + Advanced to choose the partitions you want to check for + so-called bad blocks

Tip

If you're not sure you + have made the right choice, you can click on + Previous, again on Previous and + then on Custom to get back to the main screen, where + you can choose to view details of your partitions.

When you are confident + about the selections, click on Next to continue.
