9 That is the ID of /dev/sda5:
10
11 # sgdisk -i5 /dev/sda
12 Partition GUID code: C12A7328-F81F-11D2-BA4B-00A0C93EC93B (EFI System)
13 Partition unique GUID: 0C67029A-25DE-4E23-B2BE-6C502742189E
14 First sector: 1296046080 (at 618.0 GiB)
15 Last sector: 1296455679 (at 618.2 GiB)
16 Partition size: 409600 sectors (200.0 MiB)
17 Attribute flags: 0000000000000000
18 Partition name: 'EFI System'
19
20 This is the EFI-system-partition on /dev/sda.
21 Should it point there?
22
23 In my case sda1 is a Linux RAID partition, which is part of md0, which
24 once was my / (too small now).
25
26 What I tried to achieve:
27
28 sda5: EFI system ( -> /boot/efi )
29
30 gentoo-root on /dev/md3 (consists of sda6 and sdb3)
31
32 I know this looks like a mess, and somehow it is.
33
34 But right now I see something else:
35
36 Boot0000* GRUB2
37 HD(5,4d401800,64000,0c67029a-25de-4e23-b2be-6c502742189e)File(\EFI\GRUB2\grubx64.efi)
38
39 would point at my /dev/sda5 and the file \EFI\GRUB2\grubx64.efi in
40 there, right?
41
42 After all my fiddling around right now it is named
43
44 /boot/efi/EFI/grub2/grubx64.efi
45
46 case-sensitive? Vfat ... ? I just rename it and give it a try ;-)
47
48 What about that ugly Boot0007 in my listing?
