Błąd przy próbie instalacji GRUBa
miodo07 - 07-04-2009 21:26
Zacznę od początku:
mój /boot/grub/menu.lst
# menu.lst - See: grub(8), info grub, update-grub(8)
# grub-install(8), grub-floppy(8),
# grub-md5-crypt, /usr/share/doc/grub
# and /usr/share/doc/grub-legacy-doc/.
## default num
# Set the default entry to the entry number NUM. Numbering starts from 0, and
# the entry number 0 is the default if the command is not used.
#
# You can specify 'saved' instead of a number. In this case, the default entry
# is the entry saved with the command 'savedefault'.
# WARNING: If you are using dmraid do not change this entry to 'saved' or your
# array will desync and will not let you boot your system.
default 0
## timeout sec
# Set a timeout, in SEC seconds, before automatically booting the default entry
# (normally the first entry defined).
timeout 5
# Pretty colours
color cyan/blue white/blue
## password ['--md5'] passwd
# If used in the first section of a menu file, disable all interactive editing
# control (menu entry editor and command-line) and entries protected by the
# command 'lock'
# e.g. password topsecret
# password --md5 $1$gLhU0/$aW78kHK1QfV3P2b2znUoe/
# password topsecret

## default kernel options
## default kernel options for automagic boot options

więc próbuje zainstalować gruba

Running "embed /boot/grub/e2fs_stage1_5 (hd0)"... 17 sectors are embedded.
succeeded
Running "install /boot/grub/stage1 (hd0) (hd0)1+17 p (hd0,5)/boot/grub/stage2
/boot/grub/menu.lst"... failed
Error 12: Invalid device requested
Wiem, że coś jest z menu.lst ale nie wiem co. Ostatnio nie mam czasu siedzieć przy kompie i rozkminiać więc wybaczcie, że z takim problemem się do Was zwracam. Instalowałem z konieczności windę i teraz nie mam dostępu do zainstalowanego debiana. Tylko z livecd...
prosze o pomoc

Grub "liczy" partycje od 0, nie od 1. Jedyna partycja (a właściwie dysk logiczny) z linuksowym systemem plików to u Ciebie sda5, czyli (hd0,4). Zakładam, że tam właśnie masz Debiana.
Jeśli zaś chodzi o menu.lst, to masz ustawione bootowanie Debiana z partycji NTFS, a Windowsa z partycji swap.
Najszybciej doprowadzisz to do porządku zmieniając wpisy w menu.lst na poprawne (z poziomu livecd). Następnie instalacja gruba w mbr, ewentualnie możesz użyć supergrubdiska, który zrobi to za Ciebie (link).
