Earlier today I was playing around with a toy OSdev project, and I was working on implementing the Mutliboot 2.0 standard so that I could launch it with GRUB. I finished setting up the header, and I invoked some of the tools like grub-mkrescue, grub-install, etc. to get a copy of GRUB installed on a disk image that I could use. Part of the directory tree for my project had a directory called 'boot', and I am worried that I might I have accidentally done something to '/boot' instead of 'boot'.
Later, I went to reboot my computer, and instead of the usual GRUB menu, I was greeted with the following:
| Code: | | error: symbol `grub_calloc' not found. |
and was dumped into a rescue prompt. Nothing I did in the rescue prompt seemed to fix anything, so resorted to pulling out an old USB stick, throwing a SystemRescueCD onto it, and booting that, which is where I am posting this from now.
I tried chrooting into my Gentoo disk and running
| Code: | | grub-install --efi-directory=/boot/efi |
and
| Code: | | grub-mkconfig -o /boot/grub/grub.cfg |
and
| Code: | | efibootmgr --create --gpt --disk /dev/nvme0n1 --part 1 --write-signature --label "gentoo" --loader "\\EFI\\gentoo\\grubx86.efi" |
in various orders and combinations, but on reboot I am still faced with the same error. I also tried rebuilding GRUB, but it did not change anything.
Some general information about my install:
- The system should boot using UEFI with GPT.
- The root filesystem is inside a LUKS encrypted LVM volume (but I don't think this is relevant, because the problem is occurring before we should even be doing anything with root).
- grub-2.06-r2
- efibootmgr-18
- efivar-38
If anyone has any ideas about how to fix this I will appreciate it greatly! I apologize if this has been posted before: I found https://askubuntu.com/questions/1263125/how-to-fix-a-grub-boot-error-symbol-grub-calloc-not-found and https://stackoverflow.com/questions/63204225/error-symbol-grub-calloc-not-found-on-ubuntu-boot, but the solutions given don't seem to work (unless I am missing something).
UPDATE: At the recommendation of an IRC I tried fully deleting /boot/grub and /boot/efi and reinstalling grub again. This did not help, and now I don't even get to grub at all to receive an error.
The one thing that I would like to try that isn't working is to see if there is an update to grub: when I run emerge --sync or emerge-webrsync I get errors (emerge --sync fails on "Refreshing keys via WKD ..." and emerge-webrsync attempts to fetch many files but none of them succeed).
UPDATE 2:
SOLVED!!!
I was being silly. I deleted /boot/grub and /boot/efi and reinstalled grub using grub-install --efi-directory=/boot (NOT /boot/efi). I forgot that my ESP was mounted differently than what the wiki was assuming. Then I just ran grub-mkconfig and rebooted and I was good to go. Thanks to the folks on IRC!!! |
