I am building a machine which has an EFI capable boot on the motherboard together with an mSATA drive for the root and boot partitions and an SSD for the /opt and swap partitions, and just a single arch x86_64 install when it is built - no dual booting to other OSes. I have been looking up information about UEFI with GPT partitioning and have read about various problems that people have had with such systems. So at this stage I am unsure whether to stick with what I know (BIOS/MBR and GRUB2 with full systemd) or whether to plunge into the unknown (for me!) and try EFI/GPT! (with rEFInd) Does anyone have experience with such a UEFI system on this list? Apart from the info on the arch wiki and the install wiki info (which I have been reading), are systems like this reliable once installed? Does the routine pacman update process for kernels lead to issues requiring manual intervention with EFI/GPT or it is as generally reliable as BIOS/MBR? I would be interested to hear from anyone with this kind of experience running arch - if it is useful the motherboard I am using is an Intel DQ77KB (which I intend to update with the latest BIOS firmware) and with the Intel i3-3220T CPU. Thanks for any replies (and useful links) -- mike c
