Slackware and the grub boot loader.

Alright, I'll try with elilo

elilo is for an efi system you have a legacy system, use lilo or grub, in your case dont' install a bootloader in slackware use debians grub to boot slackware.
boot debian copy debians /etc/resolv.conf to slackware /etc/resolv.conf
chroot into slackware
edit /etc/slackpkg/mirrors remove the # sign from the mirror you want to use
update your system with

Code:

slackpkg update
slackpkg upgrade kernel

This being a new system, at the prompt for new configuration file select O to overwrite old files.

Code:

mkinitrd -k <new installed kernel version> -f ext2 -r /dev/mmcblk0p2 -w 15 -m mmc_core:mmc_block:sdhci:sdhci_acpi:sdhci_pci:usb_storage:xhci_hcd:uas:xhci_pci:ext2 -u -o /boot/initrd.gz

exit out of the chroot, reboot

Instead of saying 'maybe I am wrong', why don't you go into the bios to check whether or not you are using legacy mode or uefi? - that would save a lot of guesswork for all the folks wanting to help you.
If it is infact uefi (which I believe) - then there is no way I am able to help you. As I said in a post above, I use legacy mode on all my rigs and even legacy grub.

There is no efi partition, sda1 is an ntfs partition, efi partitions are fat filesystem.
stf92 run

Code:

cat /sys/firmware/efi

if the you get no directory your booting in legacy mode.
post

Code:

parted -l

\

on a side note once a grub menu is reached efi or legacy is immaterial, to be able to boot into a system, it is all correct kernel options, initrd, config files.

When I began to look for linux distros to install on this machine (it had only windows 10 occupying the whole eMMC and there was no way to stop it making updates which would soon leave no room for my own files; the eMMC is only 32GB in size), between the several ones I tried, I found only arch and debian understood the machine. What is more, I only could installed them by setting the BIOS/UEFI to legacy mode. Perhaps there is a way to make Debian work with UEFI but, for the moment, lets assume the machine is in legacy mode, which it is.

having minimal space you might want to skip the slackpkg install-new for the time being.

I'm sorry for being stooopid, but ... you have a 32-gig disk and are trying to squeeze _3_ distros onto it??

At present this is the initrd.gz I am using.

Code:

mkinitrd -k 4.4.14 -f ext2 -r /dev/mmcblk0p2 -w 15 -m mmc_core:mmc_block:sdhci:sdhci_acpi:sdhci_pci:usb_storage:xhci_hcd:uas:xhci_pci:ext2 -u -o /boot/initrd.gz

based on the lsmod I made and suggested by colorpurple21859. And this is grub.cfg:

Only two: debian and slackware, 16GB for each. I managed, until now, with 16GB for debian and 16GB for personal data. I moved the data to a usb stick to make room for slacware. When slackware is finally installed i'll discard debian and restore the data to its partition. I always, on desktop machines, managed with 20GB for slackware. 14.2 takes less than 10GB.

try booting one of the kernels in the submenu of slackware, at the menu you will have to edit to add the initrd /boot/initrd.gz line
I edited my post 76 to only upgrade the kernel, maybe a newer kernel will fix it.

stf92 · 07-03-2020, 08:44 PM

Anyone? All the four kernels are listed. Do I try with the generics too?
