|Old dogs and new tricks springs to mind. I am building a new PC and what with
|UEFI, APUs and SSDs, it feels like that the world has moved a long way since
|the last time I had to install gentoo.
|I'll be taking my time to google, read and make appropriate selections, so
|please bear with me while I start relevant threads as necessary to complement
|my sparse knowledge in these topics. Starting from the top, with this thread
|I am trying to find out what is considered good practice as far as UEFI/MBR
|and boot management goes.
|The MoBo is capable of booting in CMS mode, but I am not sure if there are any
|benefits in creating a 2MB partition for a conventional MBR bootloader, or I
|should forego MBR altogether and go directly with a GPT FAT32 EFI System
|If the latter is the way to go and I forget all things I ever learned about
|MBR, does the 550MB FAT32 ESP partition have to be at the beginning of the
|Is it beneficial to install a Linux boot loader/manager like GRUB2, or rEFInd,
|etc., or should I just use the kernel EFI Boot Stub to boot gentoo with? The
|PC will single boot in Gentoo, although I may drop in a sysrescuecd image for
|recovery purposes and would be nice to be able to boot this straight off the
|disk, without having to burn it on a CDROM. Is it simply a matter of adding
|the LiveCD iso in the ESP with a .efi suffix, or will I need to use efibootmgr
|to inform the UEFI about *any* kernel images in the ESP other than the default
|Finally, what's your opinion on 'secure boot'? I'm mostly thinking of its
|benefit as a pre-boot malware protection utility, but I don't want to
|introduce too much complexity which may make recovery of my data difficult in
|the future. I've heard some horror stories resulting from NVRAM corruption,
|or flashing with new UEFI firmware rendering the PC unbootable, etc. but don't
|know if this is due to user error. If you have experience using secure boot
|what is your preferred method?
|Any other pointers and gotchas I should be careful with?
