I've bought a new computer with asus sabertooth 990fx motherboard (well known asus ami bios which can use uefi properly) and installed windows 8 using uefi and gpt to play wine-not-compatible games. Disc now contains partitions:

  1. ms efi boot - 100M
  2. ms recovery - 100M
  3. ms root - 100G
  4. unallocated space - 400G

I want to install gentoo by adding partitions mentioned in handbook and no touching MuStdie:

  1. ms efi boot - 100M
  2. ms recovery - 100M
  3. ms root - 100G
  4. grub2 efi boot - 200M
  5. linux swap - 16G
  6. linux root - 30G
  7. linux home - 350G

I am new to uefi booting. I was using bios + grup-pc + mbr on old computer. It is possible in this case to use only one bootloader thats why I was using chainloader to boot windows (see handbook)

Specific question: Is it possible to use two uefi bootloaders(ms + grub) in different partitions?

    Could you make your question more specific, at the moment the question is extremely vague. why do you worry that it shouldn't work? have you even tried? – Baarn Apr 28 '12 at 10:23
  • Ok I will edit question to be more specific – puchu Apr 28 '12 at 10:25
  • specific question added – puchu Apr 28 '12 at 10:36
  • of course I will try this but I think it is not bad to ask question before: maybe anyone will share his experience – puchu Apr 28 '12 at 10:59

I've succesfully installed grub 2 to the second uefi partition and both two loader works via manual (site is not working now. use google cache to see). The main trouble for me was to create bootable usb flash with uefi. But when I've done I saw uefi power => uefi + gpt + grub 2 + gentoo + windows 8 = works perfect

But then I saw that each loader is less then 50 megabytes, moved two loaders to the first efi partition and dropped the second efi partition. It works still perfect ^____^
