is it possible in grub2, that a temporary default entry. For example i have 2 menuentry in grub.cfg 0 & 1. my default is 0 but i want to automatically boot once to 1 and it changes back to 0.
View 4 RepliesI recently upgraded grub -> grub2 on my karmic box. Grub2 worked when chainloaded from legacy grub, and also the first time I tried it standalone. Both times the grub2 menu came up.
I ran vbeinfo at a grub2 command prompt, and found my monitor's native res listed - 1280x1024. I added that to my /etc/defaults/grub and then ran update-grub, and rebooted. This time no menu appeared and the default entry booted straight away. I suspected that the resolution was not supported for some reason or that the way I entered it in the config file was wrong, so I commented it out again in /etc/default/grub, and ran update-grub again - to no avail.
I have since tried lots of different formats for the GRUB_GFXMODE, such as 1280x1024@24, 1280x1024x24, and the normal 640x480, but none of them give me a grub menu. I have even tried using GRUB_TERMINAL=console, to no avail. I have checked the /boot/grub/grub.cfg file each time to make sure my changes were put there correctly by update-grub. I have also made sure that timeout was set to 10, and the hidden timeout was set to 0. My GRUB_CMDLINE_LINUX_DEFAULT="quiet".
I have reinstalled grub2, grub-pc, and grub-common, and I have dpkg-reconfigured them all too. I have no idea what to do to get my grub menu showing up again.
Here is my current setup. I have installed Windows 7 Home Premium 64-bit, Ubuntu 9.10 64-bit, and BackTrack 4 Final in that order. All operating systems are able to boot and all is working well. The only problem I'm faced with is really just an annoyance. Which is BackTrack is showing up with a "Ubuntu 8.10" entry name.
Now I did some research on this. I found out that BackTrack was based on the Ubuntu 8.10 OS so it makes sense why it would show up that way. I found several articles and topics explaining how to modify the GRUB programming files. I guess to change the entry name, but all of them don't seem fool proof to me nor the best way to go about doing things.
One thing I wasn't able to find info on is where GRUB2 actually gets these entry names from. My theory is if I can find out where GRUB gets this info from, I can simply log into the BackTrack partition and change where the "Ubuntu 8.10" entry is to "BackTrack 4" and then run the update-grub2 command within Ubuntu to update the entry names.
I have installed Sabayon 5.4 on my laptop besides Ubuntu 10.10. During installation of Sabayon I did not opt for a bootloader as I did not want to disturb the already existing Grub2 on MBR from my Ubuntu installation.After successful installation of Sabayon, I booted into Ubuntu and updated the Grub which detected Sabayon correctly. Then I rebooted and tried to boot into Sabayon but I could not do so. The booting process stopped with the following error -
Code:
Activating mdev
Detected real-root as md device. Setting up device node
Scanning for Volume Groups
[code]....
So evidently, Grub has wrongly taken the values of root as /dev/md0 and swap as /dev/sda2.I again went back to Grub2 screen edited the Sabayon entry by replacing /dev/md0- with /dev/sda4 and swap:/dev/sda2 with swap:/dev/sda8 and pressed Ctrl+x. Now I was able to boot into Sabayon. how do I make these changes permanent. Which files should I edit so that Grub correctly read root as /dev/sda4 and swap as /dev/sda8?
Ive installed a fresh copy of ubuntu onto my laptop, dual boot with 7. Everything runs smoothly except the grub. So in grub i have an entry of vista loader. I have removed the ubuntu recovery mode and the memtest entry so now i have 3 entries
Ubuntu
vista loader
7 loader
How i can remove the vista loader? PS i have never had installed vista onto my system i bought it brandy new with 7 pre-installed.
GRUB2 replaced the boot entry for Windows 7 when I installed Windows XP. I tried to create my own menu entry for Windows XP but it seamed to me that it was superseded by the Windows 7 boot loader. I have a brand new desktop PC - Core i7 processor, 2 TB hard drive, 6 GB RAM.
I don't know how to bring back a menu entry that was over written / Superseded by another OS being detected by update-grub; in this case Windows 7. I installed Ubuntu 11.04 at the end of many other Linux OS's. So it is a Multi-boot setup. Basically Windows XP has replaced the Windows 7 boot entry in the GRUB 2 Boot menu after running update-grub.
Then to get Windows 7 back I booted off the Windows 7 Install DVD and used the boot repair option. This then changed the working Windows XP Boot Loader to boot Windows 7 which I wanted but there was a catch. Windows XP didn't boot any more because it was replaced / Superseded. The Linux OS's boot fine.
I have two ide hard disks. One with windows and other with ubuntu 10.04. i want both windows and ubuntu in grub menu so what should i do ?
View 3 Replies View RelatedI have two partition in my netbook (plus swap):
/dev/sda4 with Ubuntu 10.4 /dev/sda5 with Centos 5.5
I use Ubuntu obviously. Centos is there because I need to run some test on that distro. The problem is Centos uses Grub and Ubuntu uses Grub2.
This is /boot/grub/menu.lst from Centos:
Code:
default=0 timeout=5 splashimage=(hd0,4)/boot/grub/splash.xpm.gz
title CentOS (2.6.18-194.17.4.el5xen)

module /boot/initrd-2.6.18-194.17.4.el5xen.img .....
This was generated running update-grub2 and grub-install under Ubuntu. It's not working. It gives me something like bad magic number. How can I convert the grub1 entry in a grub2 shape?
I've just installed FreeBSD 8.1 on /dev/sda4 (FreeBSD slice), without installing the boot loader from FreeBSD (I've selected None when prompted for boot loader in sysinstall). Now I want to use my existing Grub2 from already installed Ubuntu 10.10 to boot FreeBSD also.
After some reading, I've added to the end of /etc/grub.d/40_custom:
After running sudo update-grub, grup.cfg file shows my new entry. The problem is that after restart, I don't see the new entry in the grub menu.
Another question, If i used chainloader +1, that means I need to have the FreeBSD bootloader installed also on /dev/sda4 right? For chainloading booloaders?
I didn't get to that step, I first want to see the entry in the menu.
Any idea what I might be missing/misdoing? (I also checked for blank spaces in the menuentry like the wiki for grub2 says)
Having just upgraded to Ubuntu 11.04 from 10.10 I noticed that my Grub menu had not upgraded. The upgrade was not as straight forward as it should have been as the PC hung at the end of the installation resulting in a reboot and running dpkg in safe mode to get it all back up and running.
To fix the incorrect grub menu.lst file which was not updating, I renamed the original file and then ran sudo update-grub. It generated a new and correct file. However, my Windows partition was not listed as a Grub menu option.

I have a working Ubuntu install with the Grub2 bootloader. I need to manually add an entry to boot Fedora 13 off of sda. Sda1 is the boot partition, sda2 is LVM. None of the examples I've tried work. I do also have F13 grub installed on sda, but chainloading to it didn't do anything other than a blinking cursor.
View 5 Replies View Relatedi think i have found a bug in the unix ACL permissions. I tested this problem in the Ubuntu 9.10 and in SLES 10 and 11, all of them with setfacl 2.2.47.
Well, I have done the following test:
1) Create a folder and set some named user, and set the same ACL entry for the Default ACL, like the following example:
Code:
mkdir dir1
setfacl -m u:rodrigo:rwx dir1/
setfacl -d -m u:rodrigo:rwx dir1/
getfacl dir1/
# file: dir1/
[Code].....
Note that some permissions are different from the ones in the Default ACL in the dir1/
why the file1's permissions are diferrent from the dir1's default ACL entries? Is this a bug?
Lately when Fedora 12 updates the kernel it defaults to the last kernel entry and not the newest one. However I set grub to boot entry 0 as the default which is allways the new kernel. It runs like this fine until the kernel updates then it seems to change from 0 to 1 on its own is this a new planned aspect of the new kernel being installed?
View 14 Replies View RelatedWhen I boot Ubuntu 10.04 then at first the login screen appears with the main user
"Peter"
and
"other..."
In 99% of the cases I use "Peter" and have explicitely to click on Peter. Only then the password entry field appears and I can enter it.
This is somehow user unfriendly. Can I define somehow a default user (here: Peter) and show immediately the password entry field (and place the cursor inside)?
How to remove OS's from the GRUB boot menu, and also, how can I change the default booter from Ubuntu to a different OS and edit timeout?
View 2 Replies View RelatedSo I have Windows 7 and Ubuntu dual booted on my computer, and the default is Ubuntu. I was wondering if it was possible to make it such that the default is the last booted system? As in, if I was in Windows, and restarted, then GRUB would highlight Windows.The mainmotivation is to for when the computer restarts automatically (say after an update). I may not be around during the 10 seconds before it boots into Ubuntu.

View 3 Replies View RelatedI've read "Can't choose my 2nd HDD to install Ubuntu" and "How to move GRUB?".but my problem seems not exactly the same as them. I have three drives:
1) SATA drive on first port with Windows on it
2) IDE drive with Ubuntu9.10 on it
3) new SATA drive for Ubuntu10.04
I want to remove the IDE drive and put it in a safe place as a backup.
I installed 9.10 on the new SATA, intending to see if I could get Upgrade Mangager to offer me Lucid Lynx. I should have unplugged the IDE drive but I didn't. Anyway, the Ubuntu9.10 CD installer did find the new SATA disk which I had partitioned using my original 9.10 setup on the IDE. It did put Ubuntu onto the first partition of the new SATA where I wanted it. However, if I disable the IDE in BIOS I get just a blinking underscore at the top left conrer of the screen on reboot. Why would the installer do this to me? Nevermind, perhaps a better question is this: How do I check where GRUB2 has been installed and if, as I suspect, it's put GRUB2 on the IDE, what's the simplest and safest way to get GRUB2 put on the boot sector of the new SATA disk?

I wonder if its any easy way to configure grub2...I dont want to change fonts, background or anything special. Just to change default operating system time to shown menu etc.
Is there anythink like known from KDE? graphical tool to tick what I wont, choose time from list or type it in, click OK to finish and job done... without any manual typing, terminal use etc.
i initilally installed ubuntu 9.10 then installed windows 7 ,then i recovered grub2 using livecd as told in the post [URL] i did "sudo update-grub" and got windows 7 menu entry but when i select that entry windows 7 does not load but the grub2 is reloaded again.
i cant boot to windows 7.
Windows 7 have 100 mb partition "System Reserved" the grub2 points to that partition but still windows 7 not loaded.
sudo fdisk -l

I went through so many post but I haven't found the proper answer yet hope you have an Idea1. Grub2 saves only Linux OS as last selected no Windows OS2.It is possible to boot into a cdrom (drive)?
View 2 Replies View RelatedI am currently working with a cloning project using FOG on Ubuntu 10.10 (Desktop). While there is certainly a learning curve, all seems to be going well.
For the initial project, I have this "cloning network" isolated completely. Meaning, it is not connected to my main network/domain switch - FOG is handling the DHCP, I have a dedicated managed switch handling the routing between the FOG server and the client clones.
The main problem I am having is that Ubuntu is not able to resolve the hostnames of the client computers.
I know this is because I do not have DNS setup on my Ubuntu PC.
What is the best route to take in order to resolve this? Can I use bind9 to take care of it, or is that too complicated for what I need it to do?
Where is the Temporary Internet files?
View 2 Replies View RelatedI've been using Ubuntu 10.04 LTS for almost a year now in WUBI with WinXP. I'm a relative noob with Linux, though always eager to learn more. Lately, I have noticed that every now and then Ubuntu stops working for about 30 seconds or so with the hard disk light solidly on. Clicking anywhere does nothing until it wakes up and then remembers all my previous clicks.
When it doesn't do this, it works wonderfully. I can't figure out what sets it off. And some days it does it annoyingly often and other days not at all or rarely. I checked the log files and this is a sample of some troubled times:

View 4 Replies View RelatedI installed Fedora 15, which was my first real departure from Debian based Linux OSs. I absolutely love the new Gnome 3, and was able to configure F15 to work as I wanted it to. On rebooting I realized that there was no boot loader screen, that F15 just booted and didn't give me a choice as to which OS I wanted to use. Eventually I was able to configure grub to let me see the boot loader and added my old boot loader as a choice. This worked well, maybe not a perfect solution, but it worked. This weekend I installed LMDE (Linux Mint Debian Edition) to another HDD. LMDE uses grub2 and after the install F15 was not recognized.
Two questions: Is there a way for grub2 to see F15? or Can F15 be installed using grub2? I really don't mind re-installing from scratch.
Does anybody know where UNetBootin stores the temporary .isos etc.. before it extracts and puts it on the USB stick. I notice my hard drive space is going down slowly and that's the only thing I've been downloading with for the past few days.
