As a long time Red Hat/Fedora user, I'm quite new to the Ubuntu/Debian culture, and/or, to the Grub2 specific behavior.I'd like to see Grub2 system selection menu at every boot time even if I only have a single operating system, Ubuntu 9.10, on my hard drive. What should I do fot this purpose?
View 1 RepliesI'm having an odd dual-boot problem. Briefly, I can't boot Windows XP from its entry on the GRUB2 menu. If I set the disk order in BIOS so that the machine boots off the drive with Windows XP, XP starts normally. However, if I boot off the Ubuntu drive, which brings up the GRUB2 menu, choosing the "Windows 7 loader" option (why it says Windows 7 when there's only Windows XP is another question!) just makes my system reboot.
It appears there's some problem with the way GRUB2 attempts to start Windows XP. I'm also wondering why GRUB2 thinks it sees the Windows 7 loader. There shouldn't be any Windows 7 anything anywhere. I once had a Windows 7 RC install on the same disk as Windows XP, but I wiped the Windows 7 system partition and reallocated its space as just another NTFS partition. FWIW, GRUB2 is installed on the MBR of the disk containing my Ubuntu install. Windows XP has a different drive all to itself.
After upgrading to 10.10 the grub boot menu stopped showing up. I made a custom menu in grub.d and update grub finds everything, but when I restart my system the boot menu never shows. I should have two kernels. How do I get the boot menu to show every time I restart my system?
View 9 Replies View RelatedI upgraded my main box to Ubuntu 10.04 and everything runs fine, except for a problem with grub: I can't modify the boot menu in any way, I'm stuck with what grub2 thought was the optimal setup at installation time (and it got it wrong, btw). The current boot menu lists:
- my older 9.10 install in sdb2 (one kernel)
- legacy windows XP install on sda1
- my even older 9.04 install in sdb1 (two kernel versions)
- my new install in sdb3, with only one kernel (the one coming with the distro CD)
I tried anything I could think of to modify this menu:
- modify the /etc grub config file then running sudo update-grub
- using a specific app (system manager? don't remember its name)
- upgrading to the latest kernel
- removing and reinstalling grub
to no avail: the menu is still there in the above form, and I have to manually select the 10.04 (old) kernel by hand every time I reboot.
Have recently installed 10.10 and have several other OS' installed, as well as other NTFS (non-OS) partitions. After a couple of updates, my boot menu shows about 8 entries, whereas I should only have about 4... How is this fixed in Grub2?
Have installed Startup Manager, and there seems to be no option here...
I'd like have some text written on my grub2 boot menu.
In legacy grub you could just add: title Foobar and you'd get "Foobar" displayed.
I tried: menuitem "Foobar" {} grub2, but it doesn't work. Any ideas how do you do something like that?
(Yes, I know writing grub.cfg by hand is not very smart. But I have a special situation: I wrote my own grub.cfg on a dedicated boot partition from where I chainload to other grub on other partitions. Those secondary grubs generate their grub.cfgs on the fly, so everything is OK )
I've already read and tested the various guides for pasword portecting the menu items. What I need is a little bit different. I need to protect the whole boot menu so normal users cannot select any entry at all and only let the default entry boot.
View 4 Replies View RelatedI just installed Debian squeeze. I installed grub to the MBR. It uses Grub 2. Apparently I'm not supposed to edit /boot/grub/grub.cnf, but /etc/default/grub and /etc/grub.d. I looked at these and read The Readme as well as a tutorial at [URL]. I'm still not sure of what to do. When I boot up I get 4 choices: 2 for Squeeze and two for another linux distro. I would like to edit the print out I get when I boot up, as well as add the partition for XP which wasn't included.
This is /etc/default/grub:
# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
GRUB_DEFAULT=2
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet"
GRUB_CMDLINE_LINUX="" .....
I have Ubuntu 9.10, PuppyLinux431 and Windows XP on a Toshiba laptop. I like Ubuntu, but the speed of PuppyLinux is addictive, so that was my default boot until I upgraded Ubuntu which included an upgrade to Grub2.
My problem: Grub2 doesn't recognise PuppyLinux. Using information from [url] I have made an executable file named 07_Puppy in /etc/grub.d and did update-grub from root. Still no luck. I can boot PuppyLinux from the grub command line using the following commands:
Just before grub displays the boot menu, I think I see a very brief message about a syntax error, but it's gone before I can read it.
Here is the contents of my grub.cfg:

Why Grub2 doesn't see Puppy and let me boot it from the menu?
My Grub2 boot menu includes:
Ubuntu, Linux 2.6.31-19-generic
Ubuntu, Linux 2.6.31-19-generic (recovery mode)
Ubuntu, Linux 2.6.31-14-generic
Ubuntu, Linux 2.6.31-14-generic (recovery mode)
Q1) I only really need the latest kernel, 2.6.31-19, don't I?
Q2) So how can I get rid of the two 2.6.31-14 entries?
I have two hard drives - (1) 80GB (2) 500GB: the 1st HD has 3 partitions (in that order) - Windows 7, Ubuntu 10.10 & Swap. the 2nd HD is for storage only, and has 2 partitions.
I did the following - I installed Windows 7 on the first partition of the 1st HD, it booted just fine. Then I installed Ubuntu 10.10 on the second partition of the 1st HD.
Windows 7 shows in the GRUB menu alongside with Ubuntu. Ubuntu boots just fine, but when I select Windows it simply restarts the computer and the GRUB menu shows again.

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.
Here is how I created a Grub2 boot-cd with a (grub.cfg) menu:
mkdir /tmp/cdroot
mkdir /tmp/cdroot/boot
mkdir /tmp/cdroot/boot/grub
cp /boot/grub/grub.cfg /tmp/cdroot/boot/grub
cd /tmp
[code]....
NOTE: The above proceedure assumes you already have a grub.cfg file. If you don't, create one in the /tmp/cdroot/boot/grub directory
machine boots straight to Windows, Grub2 does not display the normal boot menu choices. Therefore, not able to boot into Ubuntu 9.10.Perhaps someone could look at this Results.txt file and shed some light on what went wrong.This machine was working fine for a long time, then all of a sudden, it starting booting straight to Windows.
View 9 Replies View RelatedI've read the various Grub2 posts and even the guide, but unfortunately for me I can't seem to come up with an answer to my problem.

If I hold down the left shift and then press E to edit and remove the search --no floppy line entirely then press ctrl-x the system boots just fine. I then opened up a terminal and did sudo update-grub to try that but it didn't fix it. Is this a problem in my bios looking for a floppy, I tried with the boot from floppy enabled and disabled (but always as the 3rd boot option) the floppy is not installed. Is there anyway to edit the file and save it so it will boot up? I was trying to research that and could not come up with it.
Looks like 10.10 will have grub2 and so the ability to boot on efi system. I have a macbook pro 6.2.Will maverick install on this machine as normal dual boot with no need of refit support?
View 5 Replies View RelatedBeen using Linux for many many years but Grub2 is annoying the heck out of me at the moment.
My home desktop PC is set up as follows:
/dev/sda � 40GB 10k Raptor with Ubuntu 10.10 installed
/dev/sdb � 500GB HDD formatted to ext4
/dev/sdc � 500GB HDD split up as follows:
/dev/sdc1 � 80gb NTFS partition with Win7 installed
/dev/sdc1 � Remaining drive space NTFS but nothing on it yet
Grub2 refuses to detect that Windows is installed on the 3rd HDD. I've googled and spent hours trying all sorts of things to get it to detect it and add it to my boot menu.
If I disconnect all drives except the Windows drive it boots up straight into Win7, so it's healthy and happy. (as healthy and happy as Windows can be, I need it for work purposes only!)
Does anyone have any tips on what would be the best method to force grub to realise that Windows is sitting there?
As far as I understand, the Win7 partition should be (hd2,1) � does that sound right to you?
I haven't tried booting off an Ubuntu CD and re-installing grub, since I can get into Linux and all the guides seem to be about how to restore grub after a Windows install eats it...
I recently installed Ubuntu Netbook Remix (10.04) on my brother's Acer Aspire One (751h) netbook, set up to dual boot with XP Professional. The initial install was successful, with both OS's booting correctly. However, after a series of updates and module builds (this machine has the Poulsbo chipset, still somewhat of a mess), Grub2 is now unable to boot XP, displaying the error "Operating system not found."
To be clear, grub works properly (aside from not booting XP), so the MBR is intact, although I've rerun grub-install to be safe. Restoring the windows MBR (using testdisk) boots XP happily, but of course ignores the ubuntu installation. I also had testdisk rebuild the NTFS boot sector, to no change - grub still doesn't work, the windows MBR does. Using the grub console, I can "root (hd0,1)" and see files on the XP partition, but "chainloader +1; boot" again fails with the same error. The ubuntu install can likewise mount the NTFS partition with no problems.
Given the fact that switching the MBR fixes the issue, I'm suspecting a Grub2 configuration problem. However, the simplicity of "root (hd0,1); chainloader +1; boot" leaves me stumped as to what that could be. Also, the error text "Operating system not found" is suspiciously identical to my BIOS's error message when attempting to boot from a non-bootable medium (as I found out while attempting to make a bootable usb stick with my mac).
i wiped my entire hard drive that had xp as its only OS. I freshly installed a Windows 7 ultimate and everything went perfectly. I then decided to install 10.4. I split the partitions correctly (i had experience doing this already with my laptop, which has xp/10.4). Ubuntu 10.4 install went flawlessly, except for one thing. Now when i boot up the pc, it goes straight into 10.4. I have tried holding shift during the start up to force the boot menu, and it just shows the Ubuntu 10.4 OS as choices. Any clue what i could do to make Win7 appear in the boot menu?
View 9 Replies View RelatedI've installed Ubuntu on my new desktop alongside Windows 7 (each OS is on a separate drive), I seem to have run into a small problem. Let me start with what I did:
- Unplugged 1TB drive from the PSU, BIOS was not seeing my formatted (and thus empty) 500GB drive and I couldn't put it into the boot order at all with the 1TB turned on.
- Loaded up the boot CD and was able to install Ubuntu 10.1 on my 500GB drive.
- Did a bit of configuring, shut my PC off and plugged my 1TB (with Windows 7) drive back in. I tried to see if I could now see my Ubuntu drive in BIOS but nothing is there - just the Windows drive is in the list of available drives to boot from (along with DVD-ROM and USB).
This is where I've run into my problem. What I want is to have a nice GRUB boot menu at the start like any other dual-boot system but just have the two operating systems on separate drives altogether.I did it this way because I was having issues with the advanced partition menu on the boot CD so just went ahead and followed the KISS method by unplugging the Windows drive.
I was told by a friend that if I put my Ubuntu drive into the first position in my boot order and the Windows drive in the second, then I could boot into Ubuntu and run a GRUB update command (he told me to google it) and that would create the necessary GRUB that had the entries for Windows 7 and Ubuntu.Both operating systems are 64-bit, I imagine that might make a difference in whatever help you guys can offer me. I love the hell out of both OS's and want to be able to use them interchangeably.
I have 4 OS's on a publicly used pc. I want to hide the boot menu on GRUB2 and have it appear only when I press and hold the SHIFT key during boot. Will changing in /etc/default/grub GRUB_HIDDEN_TIMEOUT to 0 safely accomplish this goal? Also, what is the command for deleting all of the former kernel upgrades from the boot menu?
View 8 Replies View RelatedI have been frustrated attempting to get Grub2 to boot a Debian Live system from hard disk. Have set aside a 4gb partition /dev/sda1 to contain the Debian Live and some other recovery tools. I actually have them all working from a 4gb USB stick successfully, but getting it to work on my HDD has proved challenging. On USB, I have PartedMagic, Gparted, Grml, and of course my standard 6.01 Squeeze. I have also managed to get the Debian Live booting from that USB stick. Very slick.
However, I can NOT get Debian Live to boot from my HDD; altho all of the others above boot fine. Have tried it two ways - one using an iSO image, which is how it is done on my USB stick. The other attempt is to copy the entire contents of the ISO to a directory.
Here are my directory structures:
debian_live_gnome_squeeze_i386- contains the following: debian-live-6.0.1-i386-gnome-desktop.iso initrd.gz initrd.img vmlinuz which is how it is laid out on my USB stick debian_live - contains the files from the ISO image The error I get is something like "panic unable to find live filesystem" My grub.cfg snippet for the two methods I have tried - the 2nd menuentry is similar to how it works on the USB stick.
menuentry "Debian 6.01 Live (on /dev/sda1)" {
insmod part_msdos
insmod ext2
set root=(hd0,msdos1)
[code]....
Probly don't really need to get it working since PartedMagic can do almost everything I need for recovery and I can use the USB for reinstall or whatever else.
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.

View 7 Replies View RelatedAfter a long night I managed to place my grub2 files on a separate partition on my hard disk. I am now able to edit my grub.cfg file directly (no more pesky update-grub commands) and I can create my own custom named menu entries in grub.cfg, the only problem I have encountered is in theming. I originally used burg to theme my menu, but found it to be a little unstable and erratic, so I have decided to use native theming options like font, color, and splash image.
But unfortunately, all the instructions for using these features invoke editing the 05 Debian script to make changes. As I no longer use this feature, I need to understand how editing the Debian script affects the grub.cfg file so I can manually create my menu. If you have themed your grub2 menu, please post the contents of your grub.cfg so I can get a feel for the what commands exist.
