problem s GRUB

caute potrebujem poradit s niecim... mam nainstalovane dva systemy, jeden win 7 a linux ubuntu. no problem vznikol po instalacii ubuntu, kde mi prepisal grub... proste ako prvy system mi vzdy ponuka ubuntu a ja chcem presny opak, chcem by prvy ukazoval windows, ako to mam spravit ? vo windowsw mi ukazuje iba win, ubuntu vobec nie.

http://wiki.ubuntu.cz/GRUB/Zm%C4%9Bna%2 ... %ADho%20OS
a vo windowse ubuntu ani neuvidis,kedze windows nedokaze citat ext format disku

zorro181 aku verziu ubuntu mas nainstalovanu?? 9.10, alebo nejaku starsiu?? ak mas 9.10 (karmic koala) tak mi ukaz subor /boot/grub/grub.cfg a ak mas starsiu verziu tak urob ako ti ac.milan pisal.
ac.milan- ten navod je pre starsie verzie ubuntu a predpokladam ze ked neuviedol aku ma verziu tak ma najnovsiu...

ano mam 9.10,

potrebujem aby sa ako default zobrazoval win s casom 3 sek... to je uz jedno... neviem kde to mam editovat aky subor...

ok, takze si otvor subor /etc/default/grub najdi si GRUB_TIMEOUT=10 a zmen to cislo ktore tam budes mat za trojku, a potom zmen z GRUB_DEFAULT=0 na GRUB_DEFAULT="Windows 7 (loader) (on /dev/sda1)"

este taky may dotaz... ako to ulozim
neviem ci robim spravne ale dal som si terminal a napisal prikaz update-grub... no vypise mi lubos@comp:~$ update-grub
/usr/sbin/grub-mkconfig: You must run this as root

v linuxe sa zatim nevyznam

zadaj prikaz sudo update-grub

no sak sa nic nedeje... prebehlol update.. ale ziadna zmena...

v tom subore default/grub to mam aj ulozit ? lebo sa to neda, je tam moznost ulozit ako... ale nemam opravnenie zevraj...

Potom to ulozis.
Ak mas nieco spustit ako root, tak zadaj pred to sudo, ak pracujes v textovom rezime (terminal), alebo gksudo, ak spustas nejaky graficky program (napr. ten gedit).

ok moc diky uz to ide ako ma v linuxe vobec nic neviem zatim... vidim ho asi 3 krat neco som sa aspon naucil, dakujem
