Booting iso images with GRUB 2

Booting iso images with GRUB 2 With thousdands of linux distributions around , booting iso images with out burning it to a cd or dvd  saves a lot of money and effort.   Let us try to boot system rescue cd. I have  ubuntu  lucid lynx installed on my laptop. Let us see how to boot   system rescue cd  from the iso image.   Get the latest system  rescue cd from here. I keep all my iso images under /boot/iso folder . You can choose a different folder. (but note the exact path) Add  the following lines to   /etc/grub.d/40_custom file   menuentry " SystemRescue CD ISO " { loopback loop (hd0,1)/boot/iso/systemrescuecd-x86-1.5.8.iso linux (loop)/isolinux/rescue64 setkmap=us isoloop=/systemrescuecd-x86-1.5.8.iso initrd (loop)/isolinux/initram.igz }  You may have to tweak ( hd0,1 ) depending on  the location of your  iso image.   The line         loopback loop (hd0,1)/boot/iso/systemrescue...

Bootmgr is missing after Grub Restore

Bootmgr is missing after Grub Restore If you windows is reinstalled after Linux, and then grub is restored in the recent versions of grub one may come across the problem in windows booting:  BOOTMGR is missing  Press Ctrl+Alt+Del to restart This is because, grub-restore will just recovers the earlier configuration file which contains the information about the UUID (Universally Unique IDentifier) of the earlier partition. A simplest solution for this is to comment the line with -fs-uuid for windows partition. To do this open terminal from Applications --> Accessories --> Terminal Then type in: gksudo gedit /boot/grub/grub.cfg Find out the menu entry for windows ie; the entry which starts with #menuentry "Windows xxxxxxxx (loader) (on /dev/sdax)"{ With in that entry put a # symbol before the line #        search --no-floppy --fs-uuid --set xxxxxxxxxxxxxxxxx Then save the file, close and restart the system to go into windows...

Download the .iso file of your favorite os from corresponding sites.if  you already have then skip the step.     for downloading ubuntu click this link.     for downloading fedora click here.     for other search the web....  :-D 2. Copy .iso file to the root of your disk or inside the folder at the root of disk.      / is root  or /your_folder/       su cp <iso file name> /                 Example: $su cp ubuntu-12.04-desktop-i386.iso /...

Bootreihenfolge ändern Anleitung Linux Ubuntu Grub Sind auf einem Rechner mehrere System installiert, dann kann dies nat�rlich auch angepasst werden. Ich wollte die Anleitung bereits vor zwei Tagen online stellen aber musste es noch einmal mit Windows probieren, damit ich mir auch sicher sein kann, dass das alles so funktioniert, wie es hier beschrieben wird. Wir �ffnen erst einmal das Terminal und f�hren diese drei Befehle aus (wie geht das?): [1] sudo add-apt-repository ppa:danielrichter2007/grub-customizer [2] sudo apt-get update [3] sudo apt-get install grub-customizer Nach der Installation k�nnen wir �ber das Startmen� (Linux Mint) oder �ber die Dash (Ubuntu) nach Grub suchen und den Grub Customizer starten. Sollte es bei euch nicht gehen, dann einfach die ALT -Taste gedr�ckt halten und einmal F2 dr�cken, dort grub-customizer eingeben und mit der Entertaste best�tigen. Passwort eingeben Kurz warten, bis alles eingelesen wird und schon sehen wir die Bootreihenfolge. Ein ...
