Hey ๐Ÿ‘‹ @[email protected] how can I fix #slackware not working with #ELilo boot manager
Are you running Slackware 15.0 or -current?

If it's -current, it may be easier to switch to GRUB, since ELILO is getting phased out. For BIOS systems LILO still works very well (many people still use it on servers).

Also, what exact issue are you seeing with ELILO? Any error message during boot or installation?

@[email protected] @[email protected] Iโ€™m seeing the window boot manager but when I choose Slackware it take just does nothing.

I canโ€™t choose lilo because my T480s uses UEFI

Iโ€™m on 15.0
Since you're on Slackware 15.0 with UEFI, one simple option is to boot the Slackware install USB and use it as a rescue system.

From there you can chroot into your system and install GRUB, which tends to work very well on UEFI systems.

Something like:

chroot /mnt
source /etc/profile
grub-install
update-grub
If Windows Boot Manager is showing but Slackware does nothing, it usually means the EFI boot entry or ELILO setup is not correct.

I wrote a small guide for installing GRUB on Slackware (15.0 / -current) if it helps:
