Hi I'm trying to help a user who experiences difficulties to boot a Ubuntu distribution. grub does not display any message on the screen even when entering the rescue mode (in a test, he suppressed the configuration file, but got no message neither). As nothing is wrong in the bootinfoscript's report, and as his PC is fitted, beside the motherboard video processor, with two NVidia GTX580M video cards, I believe the issue is video and the solution is to use the --module=MODULES parameter of the grub-install command.
However, I have no idea of the required modules to include to have grub run and the pieces of information I found at "http://www.linux.org/threads/understanding-the-various-grub-modules.7535/"; are not explicit enough for me to poke around the right ones. As the PC is BIOS based (no UEFI), my tentative list of modules would be 915resolution acpi ahci all_video ata biosdisk bufio chain cpio cpuid disk drivemap echo ehci exfat ext2 file font iorw linux loadenv mmap msdospart normal ntfs part_msdos pata pci scsi serial terminal uhci usb vga Is this list the right one ? Thank you for any help. Arbiel
