Red Hat Enterprise Linux 7 is distributed with version 2 of the GNU GRand Unified Bootloader (GRUB 2), which allows the user to select an operating system or kernel to be loaded at system boot time.
GRUB 2 also allows the user to pass arguments to the kernel.
I'm not sure if I'm missing something or what, but I can't seem to catch the boot up process at the right time with either the shift or escape keys.
To recover the grub boot shouldn’t be soooooo hard (or at least the installation should auto-link to this site!!!! not so well I have dual boot machine, xp and ubuntu 9.10 my xp broken, so i reinstall it then I follow step 2 ubuntu is up and running again but I cannot get into xp now some error like device not found or what any suggestion? Hi, I changed the command to grub-install -root-directory=/mnt /dev/sda5 but the error is the same.
, or similar, with correct information regarding the grub2 peculiarities — e.g. But again, my apologies, and sincere thanks for this post. I`m brazillian, but I`m lucky cause I can read in English.

Help Billy Bug find the proper math coordinates in either the positive or negative numbers, so that he can eat his grub.
Feed him well and you might set a new record Billy Bugs’ new math game for kids.
There`s a lack of good tutorials and howtos in Portuguese. If you use 1st method (grub4dos) after getting back to your Ubuntu distro and reinstalling grub you need to remove “grldr” “grldr.mbr” “boot.ini” & “menu.lst” from your Windows “C:\” partition.
If you don’t remove them, trying to boot into Windows will just throw you back into GRUB. Could you use space after punctuation or use quotes for every file and path (guessing that blog automatically removes spaces) because for example “C:\. ubuntu grub2 bootloader was handling everything and it was working fine until last night when i logged into my xp partition and modified to remove the recovery console option(i couldnt stand it! on my next reboot, grub2 bootloader was gone and my pc was only booting to xp on without any other options in between. this is what i used after booting with the live cd: sudo -i mount /dev/sda2 /mnt –Used both the XP and Win7 methods on separate installs of Ubuntu 9.10.
Not exactly sure what I did but after a couple of weeks running smooth as class and keeping up with my updates, suddenly when I book, I get the Grub2 list of OSs and if I allow the first option (Lucid Lynx) generic I get dumped to the command line. most meg: alapján: mount –bind /proc /mnt/proc mount –bind /dev /mnt/dev mount –bind /sys [...] Please consider this method of updating GRUB2: Fire up a terminal from the Live CD for Ubuntu 10.04.
I try to start X and am told that it is already running but I cannot get to it. I have run update-grub and it completes and creates a new file but it does not fix my problem. $ sudo fdisk -l (Note the partition number on which Linux resides) $ sudo mount /dev/sda X /mnt (Replace X with the partition number housing Linux) $ sudo grub-install –root-directory=/mnt/ /dev/sda $ sudo reboot $ sudo update-grub Credits to for the enlightening post & the awesome translation.
Create” fooled me to think that Win7 uses same method to hide files and folders as Linux does -I went from Windows XP to Windows 7 in a dual bot situation with Ubuntu 9.10. so i tried your method (2) just the first part and it worked like a charm! XP method was flawless, except I ended up editing the file so only 1 option (Win XP) was available so during boot it would pause to ask if I wanted Win XP or Grub4Dos.
After that, the grub boot menu was gone and my Asus 1000H netbook botred directly to Windows. I also had to use “sudo update-grub” from ubuntu to get Win XP to boot in correctly. you should not have to do this at all, windows should not over write an existing boot loader, it’s just irresponsible of them to continue to allow this to happen.
