linux

Hello. I can't install grub, I get an error
Installing for i386-pc platform
grub-install: error: failed to get canonical path of "/cow".
As soon as I run the
grub-install /dev/sda command, this error immediately appears...
Installing for i386-pc platform
grub-install: error: failed to get canonical path of "/cow".
what can be done?
It is installed on the machine without problems, but if I do manual marking, it is not installed. What can be wrong?
I use this manual https://losst.ru/ustanovka-zagruzchika-grub#commen...

I solved the problem with installing on gpt , everything turned out to be very simple for the bootloader section, the legacy_boot flag was missing. There should be 2 bios_grub and legacy_boot flags on the bootloader section. I
did it according to this instruction https://losst.ru/ustanovka-zagruzchika-grub#commen... section "INSTALLING THE GRUB LOADER TO GPT FOR BIOS"
I did not run such a command from the console sudo grub-install /dev/sda
and just as soon as I partitioned the disks through gparted and set the flags, I created LVM volumes for root home and swap . I launched the standard installer, indicated which partition for what, for my grub partition, indicated something like "Bios backup boot partition" and clicked the installation and everything got up without problems.
