Dobrý deň,
pri zapnití notebooku mi prebehne post a potom sa v nekonečnej smyčke vypisuje slovo GRUB medzera GRUB medzera GRUB... až to zaplní celú obrazovku a vypisuje sa ďalej. Neviem ako to opraviť. Neviete mi s tým pomôcť?
Ako sa to stalo:
Precházdzam na lin. a vyhradil som si pre lin praticiu malo miesta /mám dualboot/ tak som ju chcel zvečšiť na ukor ntfs partície /12 GB win system, 70 GB ntfs, 6 GB lin ext2, 1GB swap/ na čo som použil Paragon Partition manager /PPm/. Ten na koci zmrzol nasledoval reštart a stále pri bootovani hlaškactypu insert recovery cd patriaca PPm. Omylom som dal naištalovať už vo win, do ktoreho som nabootoval cez recovery cd, ich nejakeho boot managera a hneď som ho dal zrušiť a vratiť veci do pôvodného stavu. A tak mi zlbol grub. Dúfam že som to presne napísal.

zkusil bych opravit (nainstalovat znovu) grub http://wiki.ubuntu.cz/GRUB/Obnova (http://wiki.ubuntu.cz/GRUB/Obnova)

vypise to:
Checking if "/boot/grub/stage1" exists... yes
Checking if "/boot/grub/stage2" exists... yes
Checking if "/boot/grub/e2fs_stage1_5" exists... yes
Running "embed /boot/grub/e2fs_stage1_5 (hd0)"... 17 sectors are embedded.
succeeded
Running "install /boot/grub/stage1 (hd0) (hd0)1+17 p (hd0,6)/boot/grub/stage2
/boot/grub/menu.lst"... failed
Error 12: Invalid device requested
dalsie info:
Grub Error 12
This error is returned if the device strings syntax is correct but other than that, an error occurred that isn't defined by any other error.

Zadal jste správně oddíl, na kterém máte linux?
"Invalid device requested"

teraz mi vypiše pri bootovani "grub loadin stage1.5" ako je to normalne a stále blika kurzor ale nič to nerobí
keď som dal sudo gedit...menu.lst tak mi otvorilo prázdny súbor
pomocov fdisk som zistil že lin particia je sda6 čo sa zhoduje s hd0,6,inak som postupoval presne podľa návodu
-
náhodou nemáte zálohu menu.lst, že?
-
človek to raz nezalohuje a vtedy sa to *****,
nestačilo by skopirovať menu.lts od nejakej štandardnej inštalacie dualbootu a potom by som si poupravoval oddieli aby mi to išlo?
edit:ďakujem za pomoc, idem už spať, pustím sa zase do toho zajtra ráno, prajem pekný večer

Mám dualboot s Windows XP, ale určitě to půjde vyřešit i elegantněji. Navíc bohužel nevím jak zjistit UUID vašich disků. Třeba by se našel někdo zkušenější, kdo by věděl. Mně se tohle ještě nestalo.
Alespoň moje menu:
# 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-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 use 'savedefault' 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 3
## hiddenmenu
# Hides the menu by default (press ESC to see the menu)
#hiddenmenu
# 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
