Yes, with the clarification that there is no "mbr information on sda1". The mbr is the first sector of the disk, *not* a part of any partition. "grub-install /dev/sda" will overwrite the mbr of /dev/sda (preserving the partition table), will also modify the embedding area (the post-mbr gap with msdos partition tables) and will install modules in /boot/grub/. > > 2º Now on startup apear > - Grub... > - fd0 read error > - fd1 read error > splash screen debian grub... > y la lista de kernels... Those error messages shouldn't cause any actual problem. There are some things you could do to avoid them (modify grub-mkconfig to add "--no-floppy" to all search commands for one), but it's probably not worth doing. > > who and why try to do something with fd (the mini-itx no floppy disk, > maybe something usb like floppy) ? Your BIOS is presenting grub with virtual floppy drives. Why, I don't know. Your guess about usb-floppy is a possibility. > > I try --no-floppy on grub install but no luck. grub-install --no-floppy just prevents grub-install from probing floppy devices, it doesn't affect the resulting grub installation at all. The error messages are coming from the search commands in your grub.cfg. -- Jordan Uggla (Jordan_U on irc.freenode.net) > > Thanks in advance. > > -- > This is your badness level. > It's unusually high for someone your size. > We have to fix that. > > _______________________________________________ > Help-grub mailing list > [email protected] > https://lists.gnu.org/mailman/listinfo/help-grub _______________________________________________ Help-grub mailing list [email protected] https://lists.gnu.org/mailman/listinfo/help-grub
