Co znamená
nastavte soubor /etc/default/grub dle vašeho systému
$ nano /etc/default/grub
? Co mám konkrétně udělat?
Každopádně, když v tomhle kroku nic needituju a pokračuju dál, tak při grub-install /dev/sda i při grub-install --recheck /dev/sda to vyhodí úplně stejnou chybu, tedy Your embedding area is unusually small.
Podle zahraničních fór může být chyba v tom, že sda1 s Windows začíná na cylindru 4, tj. že se před to GRUB jaksi nevejde či co. Jednak tomu nerozumím, jednak nechápu, jak to ty Windows udělaly (když při jejich instalaci jsem ani nenechal formátovat disk) a jednak bych se bál hýbat s tou partišnou - a stejně nevím jak (gparted v live CD má všechny volby změn u disků zašedlé).
