well at least you have grub and can still boot up :^)Holding down F8 gives me the Grub Menu. BTW F8 is only showing me the NVMe drive and the 500 GB WD. Which sounds right because lilo has control over the 1 TB drive that Slackware's on.
MX Linux is first in the list, than Mint than Slackware.
And, it appears that MX Linux has the boot in the grub menu.
I was hoping to get Grub w/o having to hold down F8.
When I have more time later I'll look in the BIOS and see what the boot priority and those options are set to.
