Re: Booting impossible
I am curious. Checking in the info --boot-directory=DIR' Install GRUB images under the directory 'DIR/grub/' It means that in your example, it will be installed in /boot/efi/EFI/fedora/grub while the default is /boot On my machine there is not /boot/grub (inly a /boot/grub2) and no /boot/efi/EFI/fedora/grub Is this information correct? In addition, on which criterion would you choose between /dev/sda and /dev/sdb? the partition of /boot/efi ? > On Fedora, you need: > > grub2-install --target=x86_64-efi > --boot-directory=/boot/efi/EFI/fedora --efi-directory=/boot/efi > /dev/sda > ___ > users mailing list -- users@lists.fedoraproject.org > To unsubscribe send an email to users-le...@lists.fedoraproject.org > Fedora Code of Conduct: > https://docs.fedoraproject.org/en-US/project/code-of-conduct/ > List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines > List Archives: > https://lists.fedoraproject.org/archives/list/users@lists.fedoraproject.org > ___ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@lists.fedoraproject.org

Re: Booting impossible
Hello, The issue is fixed. But I cannot really gives a recipes. The issue was in the generation of the grub.cfg 1) It did let boot on system 1 when generated by system 2 (it looks that a efilinux and efiinitrd were missing). This let me boot on system 1. 2) When I booted on system 1, the new grub.cfg yjay generated did not let me boot on system 2. However, after I did it again and gain, it finally generated a correct file which let me boot both systems. I noted that the structure of the grub.cfg files generated differ according to with system generates it. I also noted that sometimes, some partitions which were not mounted because there were not in the fstab, could never be mounted: busy!

But on those other systems are you trying to boot a second efi OS from the first /boot/efi system? On my efi install, when I run grub2-mkconfig, it finds all the bios installations and creates menu entries for them, so I can boot them from the efi system. I will be installing a second efi system on a different disk, so I will be able to test how this works with two efi systems in a setup similar to yours.

But I have no idea. > 3) Reinstall the sda6, but then how to have the 2 systems running? > Why I would be more successful the 2nd time? > 4) Other options? I think you should create the EFI partitions on /dev/sda, EF00 (2MB), EF01 (2MB), EF02 (1GB), and then reinstall the OS on /dev/sda putting the /boot/efi in the newly created EF02 partition on /dev/sda. That will get you a working efi install of F30. From there you can clean up the F28-F30 upgrade to ensure that it too can boot efi. But I don't think you can expect to boot either of the efi installs from the other.

Hello Igor, I did not have to use your recommendations. But you say grub2-install --boot-directory=/boot /dev/sda 1) I though it was not recommended for a efi boot. 2) is it always in /dev/sda (if the /boot/efi is on sdb)? === Patrick DUPRÉ | | email: pdu...@gmx.com Laboratoire interdisciplinaire Carnot de Bourgogne 9 Avenue Alain Savary, BP 47870, 21078 DIJON Cedex FRANCE Tel: +33 (0)380395988 === > Sent: Tuesday, June 25, 2019 at 9:09 PM > From: "Igor Bezrodnik" > To: users@lists.fedoraproject.org > Subject: Re: Booting impossible > > Patrick, you need this steps to boot your system : > > Using the GRUB2 boot prompt > > If improperly configured, GRUB2 may fail to load and subsequently drop > to a boot prompt.

Re: Booting impossible
Hello, Thank for your suggestions. Here is the current situation. After I installed the 2nd boot system on sda6 with a /boo/efi on the sdb1 (the 2 systems could mount the same /boot/efi), I have never been able to boot on the original system. I have a grub2-mkconfig to generate a grub.cfg which has never work properly to boot the 1st OS (which has originally installed in fedora 28, actually, I noted large differences between the fedora 28 and fedora 30 grub.cfg files). Then, I made a grub2-install -o /dev/sda. This created a "mess", I only got a grub shell. Fortunately, I have a mbr saved for sda and I reinstalled the default mbr, and I also had a /boot/efi saved. Hence, I reinstalled the old /boot/efi. Lucky, I was able to boot on my "old" system. I booted 2 times and then I run grub2-mkconfig /boot/efi/fedora/grub.cfg because I wanted to be able to have the option of booting of 2 systems. But, then, no way to reboot, any of the systems. I tried tons of times from the bios configuration. No way. I tried to boot by using the "old" (the one which has working for the last boot) grub.cfg, and the new one, but same result. In the best situation, I could read something like: error file /EFI/x64_86-efi/increment.mod not incremented. (it was fast that it was hard to read). I do not understand, because I have 2 other machines with 2 or 3 boots (with 1 or 3 disks, one in efi and one is legacy) in fedora 30 and I cannot complain. I just see one difference for this one: it has 2 disks, the ssd in mounted in sdb (with the /boot/efi in sdb1) with one system on sdb, and the second (new) system in sda (sda6). I just do not understand why it is so much a problem. Now, what to do? It seems that I am stuck with the bios! options 1) destroy the sda6? and try to boot !!! 2) boot on the stick and make a chroot? and fix what has to be fixed? But I have no idea. 3) Reinstall the sda6, but then how to have the 2 systems running? Why I would be more successful the 2nd time? 4) Other options? Thank for your help. === Patrick DUPRÉ | | email: pdu...@gmx.com Laboratoire interdisciplinaire Carnot de Bourgogne 9 Avenue Alain Savary, BP 47870, 21078 DIJON Cedex FRANCE Tel: +33 (0)380395988 === > Sent: Tuesday, June 25, 2019 at 2:52 PM > From: "stan via users" > To: users@lists.fedoraproject.org > Cc: stan > Subject: Re: Booting impossible > > On Tue, 25 Jun 2019 11:23:49 -0700 > stan wrote: > > > working.

Re: Booting impossible
Patrick if you use uefi system once you boot do this steps: ) sudo grub2-install /dev/sda/ 2) sudo dnf reinstall grub2-efi-x64 shim-ia32 shim-x6 3) sudo grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg On Tue, 2019-06-25 at 19:20 +0200, Patrick Dupre wrote: > Hello, > > The situation is becoming worst and worst. > I tried an grub2-install /dev/sda > Now, I cannot boot at all. > I just enter in to a grub menu from here I am stuck. > Can I collect a bit of help? > > Thank. > > = > == > Patrick DUPRÉ | | email: > pdu...@gmx.com > Laboratoire interdisciplinaire Carnot de Bourgogne > 9 Avenue Alain Savary, BP 47870, 21078 DIJON Cedex FRANCE > Tel: +33 (0)380395988 > = > == > ___ > users mailing list -- users@lists.fedoraproject.org > To unsubscribe send an email to users-le...@lists.fedoraproject.org > Fedora Code of Conduct: > https://docs.fedoraproject.org/en-US/project/code-of-conduct/ > List Guidelines: > https://fedoraproject.org/wiki/Mailing_list_guidelines > List Archives: > https://lists.fedoraproject.org/archives/list/users@lists.fedoraproject.org ___ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@lists.fedoraproject.org
Re: Booting impossible
Patrick, you need this steps to boot your system : Using the GRUB2 boot prompt If improperly configured, GRUB2 may fail to load and subsequently drop to a boot prompt. To address this issue, proceed as follows: 1) Load the XFS and LVM modules insmod xfs insmod lvm 2) List the drives which GRUB2 sees: grub2> ls 3) Study the output for the partition table of the /dev/sda device. It may look similar to the following example on a dos partition table with three partitons. will look something like this: (hd0) (hd0,msdos3) (hd0,msdos2) (hd0,msdos1) or similar to this output on a gpt partition table of the /dev/sda device with four partitions. (hd0) (hd0,gpt4) (hd0,gpt3) (hd0,gpt2) (hd0,gpt1) 4) Probe each partition of the drive and locate your vmlinuz and initramfs files. ls (hd0,1)/ The outcome of the previous command will list the files on /dev/sda1. If this partition contains the /boot directory, it will show the full name of vmlinuz and initramfs. 5) Set the root partition. grub> set root=(hd0,3) 6) Set the desired kernel. grub> linux (hd0,1)/vmlinuz-3.0.0-1.fc16.i686 root=/dev/sda3 rhgb quiet selinux=0 # NOTE : add other kernel args if you have need of them # NOTE : change the numbers to match your system 7) Set the desired initrd. grub> initrd (hd0,1)/initramfs-3.0.0-1.fc16.i686.img # NOTE : change the numbers to match your system 8)Boot with the selected settings. grub> boot 9)When the system starts, open a terminal. 10)Enter the grub2-mkconfig command to re-create the grub.cfg file to enable GRUB2 to boot your system. grub2-mkconfig -o /boot/grub2/grub.cfg 11) Enter the grub2-install command to install GRUB2 to your hard disk to use of your config file. grub2-install --boot-directory=/boot /dev/sda # Note: your drive may have another device name. Check for it with mount command output.

To clarify, there can only be one fedora bootable from each /boot/efi. A single version of any other OS can also be booted from the same /boot/efi.

It sounds like you are throwing mud at the wall, and hoping something will stick. That's a recipe for disaster when troubleshooting computer systems. Calm and methodical, that's the way. I know only a little about UEFI booting, though I recently got it working. My understanding is that there can be only one default uefi /boot/efi. So, if you wanted the second system installed to be bootable directly, you should have created a /boot/efi for the second install on the disk where it was installed. You then could use the firmware boot selection to switch to the alternate if the default isn't what you want. I *think* the last installed uefi system is the default in the firmware. Do you have a rescue CD / USB stick you can boot from? You can then mount /mnt/sysimage for the system you want to repair, and chroot there to do your repairs. I think you need to re-install the shim and grub-efi. e.g. dnf reinstall grub2-efi shim-ia32 shim-x64 That system will then be the default boot for uefi. You should probably run grub2-mkconfig -o grub.cfg in /boot/efi/EFI/fedora after you do the reinstall. That should give you a bootable system to work from. This is a little out of date, but has useful information. It says there that grub-install will render a uefi system unbootable, which is your experience. https://superuser.com/questions/596317/how-would-i-reinstall-the-grub-efi-bootloader-on-fedora-linux Here's the official Fedora uefi docs. https://docs.fedoraproject.org/en-US/Fedora/18/html-single/UEFI_Secure_Boot_Guide/index.html#sect-UEFI_Secure_Boot_Guide-Tools-shim ___ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@lists.fedoraproject.org
