Joost, |
16 |
|
17 |
my current system boots from bios(mbr) not uefi. |
18 |
|
19 |
My knowlege of uefi is poor and uefi is still confusing me. |
20 |
So it may be some of my questions will looking silly for you. |
21 |
|
22 |
I now have prepared a gpt disk with two partitions, |
23 |
one efi (fat32) and one for my system (ext4) with my existing |
24 |
system already copied (dd'ed) on it. |
25 |
This existing system was one partition only, no separate boot partition. |
26 |
|
27 |
Now I want to know how the efi partition has to look after |
28 |
I have installed refind. |
29 |
|
30 |
refind can read ext4 so where have I to put the kernels? |
31 |
|
32 |
Into /boot of the ext4 partition, where they already are, |
33 |
or on /boot/efi/EFI/? which gets mounted after the kernel |
34 |
has read /etc/fstab. |
35 |
|
36 |
Can you post a tree of /boot with the esp-partition already mounted |
37 |
of your refind booted system? |
38 |
|
39 |
|
40 |
refind can only boot kernels compiled with CONFIG_EFI_STUB=y. |
41 |
|
42 |
Can refind find and boot such kernels if the exist on a second disk? |
43 |
|
44 |
I always copied my running (mbr/bios) system to a second disk, |
45 |
so if something went wrong I switched the bootdisk in bios to |
46 |
the backup disk and was up again a minute later. |
47 |
|
48 |
I did this with a simple script that edited /etc/fstab and did |
49 |
the copy by ddpt so only the differences since the last copy |
50 |
were written.So saving a fine running system before changing |
51 |
something critical on it was done in less than two minutes |
52 |
using nvme-disks which can read very fast. |
53 |
|
54 |
I will try to achieve the same with uefi, but uefi does not show |
55 |
me devices to switch to like bios did. |
56 |
How to brand the system- and the backup-disk so refind can distinguish |
57 |
between them? |
58 |
|
59 |
|
60 |
Will it be possible to have refind at an usb-stick and let it |
61 |
boot one of the two identical systems from of two different disks? |
62 |
|
63 |
The goal is to be prepared against disk failures and system failures |
64 |
and to have always have a running system to boot from and to repair |
65 |
the one that failed or to clone it to a new disk in case one of the |
66 |
disks failed. |
67 |
So the only failure able to set me offline will be a hardware failure |
68 |
on motherboard or powersupply. |
