 Posted: Tue Mar 20, 2018 3:20 pm Post subject: Custom grub multiboot installation. |
 |
|
Hello,
I have a couple of questions and a specific situation concerning uefi(nvram on motherboard) efi-file(i.e /EFI/BOOT/BOOTx64.EFI) and grub that i would like to understand.
The questions:
question #1
What is the actual boot sequence?
A. The efivars on the uefi-motherboard(nvram) are set to know which partition on which harddrive to boot.
With for example the command:
| Code: | | efibootmgr -c -d /dev/nvme0n1 -p 1 -L "Linux Mint Work (Samsung 850)" -l "\EFI\Boot\bootx64.efi" |
This is only possible with the efi-file on a fat32 partition or other suited simple partitioning.
B. The efi file starts up the OS. If on the OS grub is installed, you get the grub menu. Is this correct?
C. From the grub menu other OS's are bootable as well.
D. The final OS boots. Boot sequance complete.
I think it's just: ABCD ?
question #2
On internet I only read about copying EFI files (/EFI/BOOT/BOOTx64.EFI).
How can i create them?
What if I want to point to another OS with and EFI file?
How is the file itself generated? How does it work? Why are there different kinds of *.EFI files?
Ubuntu Windows and other distro's have different files.
Are they configurable?
I had a efi file on one drive that booted a grub menu on another drive. How?
question #3
Can i have a seperated fat32 partition with one efi file and grub? So that i can manage the complete boot proces from this partition?
I think so as it happens with a bootable usb?
I do not want the automatic Ubuntu, mint, or RHEL installer anymore.
I want one reusable and configurable boot partition, with only manual changes.
6So if i would like to install one of these distros i can ignore the default "install next to .." part.
I use and re-configure my own boot partition, overriding the default "install next to.." part.
The specific situation I want.
I have a workstation suitable for compiling. The uefi only points at the main boot partition
On this machine are 3 permanent drives and one just to (cross-)compile gentoo on, the swapable drive.
This swapable drive must be bootable and (boot)ready to fit into another computer.
So there is one permanent boot partition on the workstation with which i can boot any partition also on the swapable drive if connected.
And there is one temporarily boot partition on the swappable drive that only boots the OS on that drive.
My uefi does not have to point here as i can boot this partition if not cross-compiled from my permanent boot partition if i added this entry in it's grub.
DRIVE A /dev/sda "linux work"
partitions
#1 fat32 "the complete boot partition",uefi only points at this.
/boot/efi/*.EFI
/boot/grub/
/etc/default/grub <- grubs conf files are in here? What more do i need to run grub??
#2 ext4
/ <--root
DRIVE B /dev/sdb "windows 10"
partitions
#1 ntfs
DRIVE C /dev/sdc "linux play"
partitions
#1 ext4
/ <--root
DRIVE D /dev/sdd "the swapable drive" (cross-)compiled gentoo
partitions
#1 fat32 "also a complete boot partition, not used from workstation"
#2 ext4
/ <--root
The recepy to achieve and maintain the boot goals,above question #3.
** 1 the efivars on mobo
Add the permanent partition to uefivars:
| Code: | | efibootmgr -c -d /dev/sda -p 1 -L "Linux Mint Work (Samsung 850)" -l "\EFI\Boot\bootx64.efi" |
** 2 creating the fat32 boot partition (if not existing)
Does it have to be at the beginning of a drive? It's not mbr?
parted command or with Gparted.
** 3 removing existing automatic installed grub (if existing)
remove partition or grub files.
** 4 installing moving efi files
mount the partition
| Code: | | mount /mnt/sda /dev/sda |
move the files.
unmount the partition
** 5 install grub
chroot into the drive:
| Code: |
chroot /dev/sda1 /usr/sbin/grub-install |
the grub installation command?
Does this install all the reguired files for grub i.e. /etc/default/grub ?
In this example, other resources are mounted. I did see no connection with grub:
example adress
https://sites.google.com/site/easylinuxtipsproject/6
example resources
| Code: | | for i in /dev /dev/pts /proc /sys; do sudo mount -B $i /mnt$i; |
/dev/pts ?
/proc ?
** auto configure grub or see configure grub
| Code: |
apt-get install --reinstall grub-efi-amd64 |
** manual configure grub
| Code: |
vim /etc/default/grub |
** Done!
exit chroot
I have tried to achieve this already,spending lots of time with rebooting.
I would like to have this sorted and understood before i realy dive into Gentoo.
So I would be really glad if this is sorted. Also for reusability in the future. Some guidance requested. How do Gentoo veterans do this?
I kinda got stuck inside the theorem, see references.
I'm missing the paractical key i think.
Some help or corrections on my boot recepy are verry welcome.
Hopefully i can eventually make a bash script. So I can easily make proper multibooted installations in the future.
Then i know i know and can apply it automatically.
The been reading and trying quite a lot.

Have you tried rEFInd? Put it on a flash drive in about 10 minutes and see what minimum work maximum flexibility looks like. If you have a spare usb flash drive that contains nothing of value, suggest download a rEFInd flash drive image from http://sourceforge.net/projects/refind/files/0.11.2/refind-flashdrive-0.11.2.zip/download, unzip it, cd to the unzip directory (contains file refind-flashdrive-0.11.2.img), run fdisk -l noting what disks are listed, let's assume /dev/sda and /dev/sdb, install the spare usb flash drive, run fdisk -l again, this second list should list a new disk, let's assume /dev/sdc, assuming /dev/sdc is correct, run | Code: | | dd if=refind-flashdrive-0.11.2.img of=/dev/sdf bs=4MB |
dd can be destructive be sure of= is pointing to the correct "spare" usb. You can then reboot using F2 or delete to enter the UEFI to select the spare USB in UEFI mode as first boot choice.

Thank you DONAHUE,
I considered rEFInd and looked for more information about it.
But I do like to finish what i've started.
I tried to install grub on my fat32 partition. sda as the main boot partition.
sda= nvme0on1
fat32 partition on sda= nvme0n1p1
I tried:
| Code: |
sudo grub-install /dev/sda
Installing for x86_64-efi platform
Installation finished.No error reported
|
So this should work?
And in uefi selected the drive.
Then rebooted and got a grub shell. Not the menu
Resetting uefi to linux-work. after grub-menu started. Something broken and unable to boot linux-work.
Broken unalocated
no such device ...
invalid sector size ...
alloc magic isbroken at ...
Aborted...
Trying the linux play entry in grub2 booted now my linux-work..
Then i tried:
| Code: |
sudo grub-install /dev/sda
# or for efi i should have {
sudo grub-install --target=x86_64-efi --efi-directory=/mnt/nvme0n1p1/boot
#}
Installing for x86_64-efi platform
Installation finished.No error reported
|
mount
| Code: |
sudo mount /dev/nvme0n1p1 /mnt/nvme0n1p1
|
grub config.
| Code: |
su
mkdir /mnt/nvme0n1p1/EFI/Boot/grub/
exit
|
| Code: |
grub-mkconfig -o /mnt/nvme0n1p1/EFI/Boot/grub/grub.cfg
Generating grub configuration file..
Found linux image: /boot/vmlinuz
Found initrd image: /boot/initrd.img
Found Windows Boot Manager
Found LInux Mint
Found Windows Boot MAnager
Adding boot menu entry for EFI firmware configuration
done
|
According to
https://wiki.archlinux.org/index.php/GRUB
This should already be it.
IN uefi selected the drive known as nvme0n1p1 (sumsung 960)
Grub commandline. NOt grub menu..
But if i select Ubuntu (samsung 960 evo) in uefi
I get a grub menu.
This grub menu is different then what i used to have.
My originat linux work does not boot.
But selecting my linux play boots now linux work...
How to verify??
The partition boot partition fat32 only contains
the folder:
| Code: |
EFI/Boot/grub/grub/grub.cfg
EFI/Microsoft
EFI/Ubuntu
|
To verify installation location:
After trying the boot info script.
The grub install is still on /dev/sdb !!!
And not on /dev/nvme0n1p1
So it's still the old situation.
https://sourceforge.net/projects/bootinfoscript
The result from bootscript:

Conclusion the grub location is still the same as the original situation:
Grub Legacy0.97 is installed in the MBR of /dev/sdb and looks at sector
981762096 of the same hard drive for the stage2 file. A stage2 file is at
this location on /dev/sdb.
Stage2 looks on partition #1 for
/boot/grub/menu.lst..
The point is that i think after reading the org grub manual that the solution must be very simple..
https://www.gnu.org/software/grub/manual/grub/grub.html#Installing-GRUB-using-grub_002dinstall
So once it's working it's just a matter of manually changing the grub conf. file.
In this link it also seems very simple.

I have not tried this one yet(im not at workstation now,laptop):

Sorry for my late response

I don't understand

This is correct. At the first topic i made pseudo names for not making my question to complicated. So there i named nvme0n1, sda. Therefore sda=nvme0n1. Sorry for the confusement.
I am about to use only one ESP. Which I want completely at nvme0 for boot speeds.
And I have one temporarily on my swapable drive.
For example I have a Mac G5 (Powerpc architecture) I do not want to compile Gentoo on it.
However I am crosscompiling on this workstation I want to create a ready to boot harddrive. So then I would technically have 2 ESP's. But the drive will be in the G5 asap.
So then:
| Code: |
#For removable installs you have to use --removable and specify both --boot-directory and --efi-directory:
grub-install --efi-directory=/mnt/usb --boot-directory=/mnt/usb/boot --removable
|
What I did on my workstation was:
| Code: |
sudo mount /dev/nvme0n1p1 /mnt/nvme0n1p1/
#on uefi must be this command:
sudo grub-install --target=x86_64-efi --efi-directory=/mnt/nvme0n1p1/EFI/ --boot-directory=/mnt/nvme0p1/EFI
sudo grub-mkconfig -o /mnt/nvme0n1p1/EFI/Boot/grub/grub.cfg
|
Hopefully I can boot completely from nvme0n1 now.
I reboot now and see. Getting there  . |

The grub menu still resides on sda.
After editing:
| Code: |
sudo vim /boot/grub/grub.cfg
|
I could tell the changes from the grub menu.
So after:
| Code: |
sudo grub-install --target=x86_64-efi --efi-directory=/mnt/nvme0n1p1/EFI/ --boot-directory=/mnt/nvme0p1/EFI
sudo grub-mkconfig -o /mnt/nvme0n1p1/EFI/Boot/grub/grub.cfg
|
The working grub menu is still on sda, not on the nvme0n1. |

It would be absolutely great to edit the grub.cfg with grub2 syntax. Actually I will do that.
the only problem now is that grub currently uses:
| Code: |
sda: /boot/grub/grub.cfg
|
and not:
| Code: |
nvme0n1p1: /EFI/boot/grub/grub.cfg
|
If this latter is the case, I think i'm almost ready. Then I can finetune, save the proces in a script and use over and over again
depending on how I want to configure my system.
It's just that i want to isolate the complete boot process to one partition,the one on nvme drive, completely independent.
In case I pull all my sata-harddrives out i can still boot grub on nvme. The grub menu would be meaningless, but still there,except the Gentoo os option, this will be also on the nvme. Once i put my harddrives back in i can boot them.
So no grub installation stuff, just running my script that will be based on this topics knowledge .
Or just a ready to go partition which i can mount and copy on any harddrive for external use. So once this works i store the partition. Or the script to generate this boot partition.
Therefore I wanted to use grub for multi platform usage.
Thanks! |

What is UEFI trying to boot? Let's make sure it is trying to boot what you want and not from the MBR.

In uefi only the boot option "960 evo Ubuntu" is selected, no other.

I'm surprised grub didn't add a UEFI boot entry when you tried to install it from Gentoo. It must have failed somewhere. It just uses efibootmgr to add another entry that points to a different grub efi stub.

I have not installed Gentoo yet.
This is system preperation pre-Gentoo.
I have got a bit further.
Succes: adding the entry in uefi
| Code: |
efibootmgr -c -d /dev/nvme0n1 -p 1 -L "MyGrub Samsung 960" -l "/EFI/Boot/bootx64.efi"
|
Succes: installing and configuring grub
| Code: |
sudo mount /dev/nvme0n1p1 /mnt/nvme0n1p1/
sudo grub-install --target=x86_64-efi --efi-directory=/mnt/nvme0n1p1/EFI/
sudo grub-mkconfig -o /mnt/nvme0n1p1/EFI/Boot/grub/grub.cfg
|
After adding the drive name in the boot entries inside the /boot/grub/grub.cfg files on nvme and sda i could monitor which grub was actually booted.
It kept booting the grub on sda while in uefi the "MyGrub Samsung 960" was selected. Conclusion the efi file pointed at the wrong grub installation on the sda drive.
After renaming and copying the *.efi files the result remained the same.
I discovered the problem I had was that i was unable to configure the (encrypted or so) /EFI/Boot/bootx86.efi file.
Now i hope i got it:
| Code: |
bootctl --path /boot/efi install
|
Hopefully i can (finally) configure and install the efi file to boot the grub on nvme! Then i'm finished.
How does bootctl work? The *.efi files are crypted so install and configure would need an "bootctl update" which is not in:
https://wiki.gentoo.org/wiki/Systemd-boot
Would this do the trick?
1. bootctl --path mnt/nvme0n1p1/efi/boot/grubx64.efi install
2. configure files to boot nvme.. i.e.
/mnt/nvme0n1p1/boot/efi/loader/loader.conf
| Code: |
default mygrub
timeout 0
|
/mnt/nvme0n1p1/boot/efi/loader/entries/mygrub.conf
| Code: |
title MyGrub
linux /vmlinuz # Do i need a kernel to boot grub?? 8-s
options root=/dev/nvme0n1p1
|
3. "bootctl update" or "bootctl --path=esp update"
This so that finally the correct grubx64.efi file is created and configured so that it will boot grub on my /dev/nvme0n1p1
I haven't tried. I think this is the solution.
So how do i point
"/mnt/nvme0n1p1/EFI/Boot/bootx64.efi"
to boot "/dev/nvme0n1p1"? |

What about?
| Code: |
sudo grub-install --removable --target=x86_64-efi --efi-directory=/boot/efi/
|
The remobable flag makes the command generate an .efi file according to on of the answers on:

| It should work without --removable, EFI system partition need to be mounted at /boot/efi. No need for sudo if you use SystemRescueCD. |
