Bug Description

I have a motherboard with 6 connections for HD/CD's and I have 1 CD and 4 HD there. There is no problem whatsoever with accessing all HD's via any OS. GRUB worked fine until 2 months ago, and allowed booting from any HD, which I used for a couple of years. Some update or something else happened, and now GRUB cannot boot from the 4th HD. If I go to the command line interface and do ls, it only shows the first three. GRUB gives no clear error when booting from the menu, it just leads to a permanently black screen. grub.cfg has all the information needed for booting from the fourth HD, but GRUB itself fails (without error messages) when one tries to boot to an OS on the fourth HD.

Grub customizer used os-probe and gets all the information about an OS on the fourth HD, and stores correctly, but something is missing from the boot sequence that tells it about the fourth HD. The boot sequence that Grub Customizer generates gives the UUID correctly, but GRUB itself cannot find it, probably because it only searches through HD's it knows about and it hasn't been informed about the 4th one.

I would simply like to go back to the situation I was in 2 months ago, when I had 3 OS's on the 4th HD and they booted perfectly every time.
