 Posted: Mon Apr 16, 2018 3:23 pm Post subject: Grub2 and EFI issues [SOLVED] |
 |
|
So I'm at the part of the install where I need to set up grub2, and I've run into an issue.
I went with the suggested partition scheme from the handbook, since bootloaders have changed since I last paid attention to them, and ran into this issue:
| Code: | Installing for x86_64-efi platform.
grub-install: error: cannot find EFI directory.
|
Here's what I've tried:
| Code: | (chroot) livecd /etc/init.d # fdisk /dev/sda
Welcome to fdisk (util-linux 2.30.2).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
Command (m for help): p
Disk /dev/sda: 931.5 GiB, 1000204886016 bytes, 1953525168 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disklabel type: gpt
Disk identifier: 75D783FC-B7ED-44D1-BFAF-19044087BAF9

/dev/sda4 33822720 1953523119 1919700400 915.4G Linux filesystem

(chroot) livecd /etc/init.d # grub-install /dev/sda
Installing for x86_64-efi platform.
grub-install: error: cannot find EFI directory.
(chroot) livecd /etc/init.d # mount -o remount,rw /sys/firmware/efi/efivars

Any ideas?

Can you also post the output of "parted -a optimal /dev/sda". Then use p for print and q for quit. It shows what flags are used better than fdisk. Also I can't recognize what's the filesystem on your /dev/sda2.
This is what I get with parted:
| Code: |
luthien ~ # parted -a optimal /dev/sda

/dev/sda wird verwendet

1 1049kB 3146kB 2097kB grub bios_grub

3 2003MB 275GB 273GB Crypted Gentoo / msftdata
|
You need the flags boot and esp for the EFI-Partition and it has to be fat32 (vfat). |

Looks like I'll need to look up how to change that partition format. Wish that was mentioned in the partitioning section of the handbook. |

Yes you need to change the filesystem of /dev/sda2 in fat32.
The reason is that UEFI-BIOS don't understand something different. Also when you want to integrate Windows later, that also wouldn't work with ext2. |

Why would I want to do that? |

| That's a design pattern. fat32 is the lowest common denominator possible for different systems to make multiboot possible. Your personal use of it doesn't matter. |

I was just ribbing you for your use of "when" rather than "if".
And switching to vfat worked. Apparently that partition is small enough it decided to use fat16! |
