I did the August update, and ran grub-install as advised. Upon re-booting I get ‘grub_calloc not found’.
So I fired up a live boot and did:
manjaro-chroot -a
grub-install --target=i386-pc --recheck /dev/sdb
grub-update
Everything ran perfectly, but on re-boot I get the same error.
I have no EFI partition on my boot disk, so it must be an MBR-BIOS system. What am I doing wrong?
I followed this article GRUB/Restore the GRUB Bootloader - Manjaro Linux to chroot and to restore GRUB for my EFI system and it fixed this issue (had the issue after updating my bios, after reinstalling GRUB).
I have booted with USB ISO; that is how I am attempting the rescue. Unfortunately, from there I cannot login to this forum, heaven only knows why. I’m logged in here now on my Windoze machine. It will take some maneuvering to get you those outputs.
I have my BIOS configured to boot the USB when it is inserted, otherwise the installed disk.
The inxi command gives me an error, wants a newer kernel (the ISO that I downloaded today uses 5.6…).
The parted command shows only what I already know and described above.
The directory does exist, and the efibootmgr output is here: efibootmgr - Pastebin.com
I downloaded the latest Manjaro ISO and put it on an USB stick, and that is what I am running so that I can fix the grub on the installed disk.
Yes, the first disk (1TB) is /home and a couple data partitions. The second is my boot disk, and AFAIK it is MBR. I can’t see any EFI partition on it. The third disk is my USB stick running the rescue system.
My boot disk has nothing in /sys (under chroot), and no /boot/efi directory in sdb5.
I’m not sure what you mean. My boot disk has a Windoze partition, but I can’t boot it because grub is broken. My USB has an EFI finder function, and it finds nothing. It also doesn’t list the Windoze partition.
EFI require GPT and existing /boot/efi for Grub install
have you an another disk ( external disk) for backup ?
because it will require Backup , format GPT and restore backup
2 two disks ( you need another one )
trying by convert MBR to GPT disk ,
it possible for windows ( need a USB windows for that ),
hard for your linux
require convert , get UUID , chroot for update /etc/fstab , re -chroot for grub install EFI
or backup and restore on GPT with adding /boot/efi
( chroot for update /etc/fstab , re -chroot for grub install EFI)
Are you telling me that, because of this latest update, my machine will no longer run in MBR mode? How can that be? How likely is it that I am the only one running MBR?
I’ve been spelunking in my BIOS. I’m beginning to think my machine is going wonky. My boot order keeps getting reset. Maybe the NVRAM is losing it, or at least the battery.
Update. This time, for the first time, manjaro-chroot finds the Windoze partition. Maybe that had something to do with the twiddling I did in the BIOS. And now, magically enough, it all works as expected. Sometimes I have to be satisfied with success.
Thanks for your help.
Note that I have edited this reply because the forum wouldn’t let me add more than 21 replies as a new user. How goofy is that? In fact, the only reason I’m here as a new user is because suddenly today, for the first time, my real account doesn’t let me log in, or reset the password.
