-==== Raided EFIBOOT ====
+==== Raided EFI-BOOT ====
-There are some problems when raiding the efi-boot. I would suggest to use:
+Nowadays, UEFI is always the best choice to boot. UEFI- Boot is quite straight forward: You first take some device, make it gpt- partitioned, create a partition (i would at least take 500 MB today, better 1GB in size), format that partition with FAT32 and mark the partition as efi-boot via the partition flag. Thats all. After some OS installed to that partition in a UEFI- way, the bios can load those files and start the OS.
+Unfortunatelly, the designers of UEFI forgot, that if your not using hardware- raid (which i don't recommend, as your losing the ability to switch harddisks between your hardware), there is no standard way to raid the partition as FAT32 is not suitable for that (way too old filesystem).
+Fortunatelly the designers of OSS software- raid were smarter: They found a way to work around that.
+So I would suggest to use two disks both partioned with gpt and same sized efi-partitions and before creating the FAT32 filesystem do software raid on it. E.g.:

 The important part is metadata=1.0 - this format has especially designed to fit the needs of raid1 of fat/efi- systems.
+You than install your Linux to that md- Device. If its not found in the beginning of the installation, scan for raid- devices or just create it while installing.
