 Posted: Thu Jan 03, 2019 1:49 am Post subject: configuring grub [SOLVED] |
 |
|
First time installing with gpt (still using bios, though :) ).
I quote from https://wiki.gentoo.org/wiki/GRUB2
| Quote: | | When using a BIOS-based system, set GRUB_PLATFORMS variable to pc to avoid unneeded dependencies. |
That does not work.
| Code: |
# grub-install /dev/sda
grub-install: error: /usr/lib/grub/x86_64-efi/modinfo.sh doesn't exist. Please specify --target or --directory.
# ls /usr/lib/grub/
i386-pc/
|
Partition table begins (sda2 is boot and sda4 is /):
| Code: |
Device Start End Sectors Size Type
/dev/sda1 2048 8191 6144 3M BIOS boot
/dev/sda2 8192 131071 122880 60M Linux filesystem
/dev/sda3 131072 8388607 8257536 4G Linux swap
/dev/sda4 8388608 41943039 33554432 16G Linux filesystem
|
Is the directive on the wiki page incorrect, or am I doing something wrong?

| Code: | grub-install --grub-setup=/bin/true /dev/sda
|
Control of the installation.--> "020" is expected, | Code: | hexdump -v -s 0x80 -n 2 -e '2/1 "%x" "\n"' /dev/sda
|
if not | Code: | grub-install --recheck /dev/sda

Thanks, curmudgeon,
I have 2 additional USE enabled in my installation.
| Code: |
fonts Build and install fonts for the gfxterm module
mount Build and install the grub-mount utility |
Otherwise, everything is the same.

I knew those can't be required.
Went back to the wiki page, and saw:
| Quote: |
grub-install accepts a --target option to set the CPU architecture and system platform. If unspecified, grub-install will attempt to guess the correct values; on an amd64/x86 system it will use i386-pc by default.
|
So I tried:
| Code: |
# grub-install --target=i386-pc /dev/sda
|
And that came back:
| Code: |
Installing for i386-pc platform.
Installation finished. No error reported.
|
No guarantee that it boots, but at least it is progress. |

Surely I miss this wiki section, thanks for the post. |
