I'm reading a lot of documentation about partitioning on EFI machines, but I have a lot of doubts I cannot clarify. First of all:

• I am focusing on a Linux-only laptop. I am not interest in dual-booting linux (Windows 8 OEM that was included in the laptop was removed by mee the day after I bought it).
• EFI boot is setted as "legacy mode" --> my lenovo EFI menu does not allow me to disable SecureBoot (that I don't want to enable), so my only remained choice is legacy mode (this way SecureBoot will be disabled).

I am used to use gparted to change HD partitions, but I am used to use gparted on old BIOS.

My starting questions are:

1. Do I have to create a partition for EFI boot even if I setted legacy mode? Wich kind of file format should be used? (fat32?)
2. If I have to create EFI partition boot how can I "save" informations (If I needed them) from the current HD Efi partition? I mean... if I change all partitions from scratch, I'm afraid I can lose fundamental settings that allows the laptop to boot properly
3. Can I use LVM if my UEFI is setted as "Legacy"?

The general idea I have is:

• having a partition (if needed) for EFI - Primary Partition (using old-bios terms) - don't know what file system (FAT32?)
• having a partition for /boot where I can put grub (ext4) - Primary Partition
• having a partition where I can use LVM - (primary partition - did I need some file system in particular?)... all the virtual LVM would be ext4 (except for swap partition)... the idea is to separate /home from the rest of the system, allowing me to resize the space of /home if it is not enough (or too big)

But I don't know if I'm missing something... And I'd like to be sure to avoid any trouble on booting before proceding. Currently my system is working with the original (manufacturer) partions (wich are a bit unefficient, imho), where Ubuntu was installed in the biggest partition (where Windows8 were originally installed).

My starting questions are:

1. Do I have to create a partition for EFI boot even if I set legacy mode? Which kind of file format should be used? FAT32?
2. If I have to create EFI partition boot how can I "save" information (if I needed them) from the current HD EFI partition? I mean that if I change all partitions from scratch, I'm afraid I can lose fundamental settings that allows the laptop to boot properly.

• don't know what file system. FAT32?
