En:HOWTO: Manual Partitioning with Sabayon Linux

This is a visual walk through about manually partitioning your Harddisc, during the setup of Sabayon Linux.
When the Installer comes at the partitioning scheme, select: Create Custom Layout.

then select the free space where we want to install our Sabayon and Click on create.

You will be asked what kind of partition you want.
Here i've chosen for a standard Partition. Other options are: RAID and LVM.
For every other partition you're creating, this will be asked., so select standard partition

The first partition to create is the /boot partition. As file system type, i've chosen ext4.
Most common file types for a /boot partition is ext2, ext3 ext4. I've chosen a fixed size of 500 Mb, but my PC is used for developing reasons so I need more space for more kernels, you can easily choose 100 Mb that is more than enough for the common user.

Click again on create.

Now we're going to create a swap partition, as for the size I've chosen 1500Mb that is a decent space but you can choose more if you have more than 1Gb ram.

Then we need to create a root partition as before.

For the root partition we're going to use all our free space left, and as for the fs type...I've chosen ext4
but basically you can fill in any type you want.
Select fill to maximum allowable size.

This is our final configuration so far.
As you can see, there is no need to create a Extended partition., Linux does this automatically for you.

When done installing, Sabayon asks you to reboot.
