[Solved] UEFI + Partitioning + Bootloader = Hell

Question

I've installed arch twice before this one, those were like a lovely stroll in the park compared to this Clockwork Orangesque torture i've been putting myself through. This time it's different because I have a system with UEFI firmware and I cannot for the life of me sort out this beginners guide to get this thing up and running.
As stated in the guide I verified through
efivar -l
that I am infact booted up through UEFI Mode.
It later goes on to recommend that I used GPT for my setup for UEFI booting.
It is recommended to always use GPT for UEFI boot, as some UEFI firmwares do not allow UEFI-MBR boot.
So I follow the instructions for creating GPT Partitions: https://wiki.archlinux.org/index.php/beginners'_guide#Using_cgdisk_to_create_GPT_partitions
Which tells me to create just two partitions: Root and Home
Later on in that same page however: https://wiki.archlinux.org/index.php/beginners'_guide#Create_filesystems
It tells me that I need to:
For UEFI, you should format the EFI System Partition (for example /dev/sdXY) with:
# mkfs.fat -F32 /dev/sdXY
With very little to elaborate on this earlier in the page. Although it does mention that:
If you have a UEFI motherboard, you will need to create an extra EFI System Partition.
But it gives no indication how large this partition needs to be.
I then find this:
https://wiki.archlinux.org/index.php/Un … _Partition
The EFI System Partition (also called ESP or EFISYS) is a FAT32 formatted physical partition (in the main partition table of the disk, not LVM or software raid etc.) from where the UEFI firmware launches the UEFI bootloader and application. It is a OS independent partition that acts as the storage place for the EFI bootloaders and applications which the firmware launches them. It is mandatory for UEFI boot. It should be marked as EF00 or ef00 type code in gdisk, or boot flag in case of GNU Parted (only for GPT disk). It is recommended to keep ESP size at 512 MiB although smaller/larger sizes are fine (smaller sizes provided it is higher than the minimum FAT32 FS partition size limit (as mandated by FAT32 specification from Microsoft).
(BTW, who uses mebibytes instead of megabytes?)
So... yeah... this was mostly a rant of sadness, after I get this thing up and running (After like 3 hours of beating my head against a wall and like 4 hours trying to get this to work) I really need to fix that friggan wiki... so that the next poor bastard that comes through, doesn't have to endure this PTSD enducing psychological torture...
My major issue was that I was not creating an EFI Partition for the GPT. Without which the bootloader (Gummiboot) is unable to communicate with the UEFI Firmware.
=============================================================================================
Solution - My two major mistakes were failing to create an EFI partition and using syslinux instead of gummiboot
=============================================================================================
1. Verify that your system is booting in UEFI Mode
https://wiki.archlinux.org/index.php/Be … _UEFI_mode
efivar -l
If you are in UEFI Mode, your system will output a list of UEFI Variables properly, if you are not, you will receive an error.
Continue on with the beginners guide as usual until you reach the "Using cgdisk to create GPT" portion
https://wiki.archlinux.org/index.php/Be … partitions
2. Create partions with cgboot (This was a crux for me, I didn't include the EFI Partition)
cgdisk /dev/sda
Choose New (or press N) – Enter for the first sector (2048) – type in 15G – Enter for the default hex code (8300) – Enter for a blank partition name.
Press the down arrow a couple of times to move to the larger free space area.
Choose New (or press N) – Enter for the first sector (2048) – type in 512M – Enter for the hex code for and EFI partition (ef00) – Enter for a blank partition name.
Choose New (or press N) – Enter for the first sector – Enter to use the rest of the drive (or you could type in the desired size; for example 30G) – Enter for the default hex code (8300) – Enter for a blank partition name.
here's how it will look
Part. # Size Partition Type Partition Name
1007.0 KiB free space
1 15.0 GiB Linux filesystem
2 512 MiB EFI Filesystem
3 123.45 GiB Linux filesystem
Now continue on with the Beginners guide until you reach the boot loader partition, I used Gummiboot successfully by following the simple instructions:
https://wiki.archlinux.org/index.php/Be … #Gummiboot

Answer 1

2) First install was in January 2007.
3) In total? 5-6 times. As a UEFI install? 2 times (including last Wednesday like I mentioned in my post).
1. Exactly, You're an arrogant, condescending snob that's been doing this for quite some time. Congrats, you can put together a linux box... well I would certainly hope so, you've been doing it for over 15 years now. But don't forget there was a point that even you had to overcome the learning curve and just because it's simple and clear to you, doesn't mean there aren't people out here that don't have 16 years of linux centric "common sense" behind them. Your current level of expertise is a cumulative evolution of 16 years of study and exposure and that is something you should take pride in, but being an arrogant twit about it just makes you look like a douche and it epitomizes exactly what gives the linux community a bad rap.
2. This Arch Wiki is (compared to most) massive, it's not streamlined, it has several passages that may or may not be used depending on the person, their equipment, preferences etc etc...  So forgive me if I didn't read the parts telling me to configure my keymap to a language I don't need to configure it too. It also links to other pages without giving full elaboration on why. It eventually leads you through several rabbit holes and isn't clear by any means to someone who doesn't do this on the regular.
3. I get that Arch isn't a COTS windows solution... it does have a level of difficulty that must be overcome, and it does require research, (which I am totally all about doing, and if you'd read my post, you would see that I never asked directly for an answer, instead I was trying to offer solutions to make the wiki itself better, because there was something omitted within an example) but there is also a great community behind it, that does (or so I thought) work hard to help its user base through forums and documentation. But your previous post, was completely nonconstructive, and served no purpose other than to stroke your own overblown ego.
