Zdravíčko,
potřebovala bych se zeptat ohledně GRUB2. Jelikož nepoužívám Ubuntu, tak jsem z toho nějak mimo i po přečtení různých dokumentací. Jde hlavně o to, že na PC kde byl původní systém W7 jsem z flash disku nainstalovala Ubuntu 10.10. A po instalaci mi nenajede vůbec Grub nabídka tzn. že už se do winu nemohu dostat. Když jsem zkoušela hrabat se v grub.cfg podle dokumentace na webu tak mi to celé spadlo a musela jsem přeinstalovat grub na novo. Neví nědko jak zprovoznit grub nabídku nebo případně jak přeinstalovat zpět grub2 na GRUB?
děkuji za reakce :-)

kdyz pri zapnuti pocitaci zmacknes SHIFT, objevi se ti nabidka Grubu?
windows, ktere chces bootovat, mas na oddile oznacenem cislem 3, nebo 5, nebo 6?
-
A jak dostanu windows do nabídky grubu?
-
Dá se teda nějak upravit přímo ten .cfg skript nebo něco aby se mi v té nabídce objevil i windows?
-
Pridanie Windows 7 do GRUBU mi našlo ako druhý odkaz na googli....

Hmm po tom co jsem vytvořil vše přesně, tak jak je to na to návodů, grub nenajede vůbec ani po stisku shift.... :-(

To je divné, ja som to podľa toho robil pred piatimi dňami.
