Hello, I installed a gentoo on a very recent system (efi support) . AT the reception of the laptop it was a disk label msdos, with a boot partition w** installer ... I changed that against a GPt disk label. I can install without problem the gentoo , but now it doenst boot.
I read some docs about gpt,mbr,boot principles and tried some tools - install the grub2 masked package and grub-install. - a special partion bios_grub as 1st bootable partition. but actually no succesful... but in the parted i did not see this "bios_grub" as flag... I found some tips from the web , but i guess that was only valid for a macintel system, not a normal pc with a disk labeled gpt and an efi support. I know that it is not required an efi partiton to boot the os with pc/bios and gpt disk. Or is it false ? If anybody has an other idea. Or I must abandon the gpt disk label ? Is there an equivalent refitr in OS x86 ? Thanks Best regards Claude
