Xubuntu 9.10 is on my master drive, and I use it to install/update grub.
When I installed Fedora, I answered "NO" to installing a boot loader.
After install, I booted Xubuntu and ran update-grub, grub couldn't find (apparently) my new fedora install.
I've tried adding it to /etc/grub.d/40_custom, and when I list /boot/grub/grub.conf, it appears to have added Fedora to the bottom of the menu.
When I boot, it doesn't stop at the grub screen, indicating only one installation of linux.
Here are the pertinent file listings, can you see where I've gone wrong?
Code:
dav@dav-desktop:~$ cat /boot/grub/grub.cfg

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.

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)?
I 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.
I was installing Fedora 13 on my computer as I need it for a class I'm taking but wanted to keep Ubuntu (10.04) as well. So now the setup is: Windows 7 on sda, Ubuntu and Fedora on sdb.I did not install the bootloader when Fedora 13 prompted to. Running sudo os-prober and sudo update-grub only finds Windows 7.I know I can manually add it in 40_custom but have no idea how to go ab out that. The output of my fdisk -l is as follows:
I am desperately looking for a how to : multiboot. Checked bodhi.zazen's thread, but its totally with reference to GRUB Legacy. I have karmic installed and also vista. wondering if there is a step-wise guide to multiboot with reference to Grub2. I want to add a SUSE, Fedora and Lubuntu, but have no clue as to how. I messed up my comp earlier trying to multiboot so now I just dual-boot Windows Vista and Karmic Koala.
I just installed Ubuntu 10.10 on my computer which Windows 7 and Fedora 14 have already installed. After rebooting, the menu list of Ubuntu which is grub2 does not contain an option for Fedora 14.
I typed sudo /sbin/fdisk -l and the result is: Disk /dev/sda: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xae33e99a

My Ubuntu partition is /dev/sda8 and my Fedora partition is /dev/sda6. Grub2 seems to be more complicate than grub1.
I have just converted from using Arch Linux for the last year to using Fedora 14. So far I have been having a blast but I really enjoy the idea of putting /boot inside an LVM container and that is how I had my Arch system built. So I wanted to do a learning experience and did a standard install on my 60GB SSD. Which ended up with a 500MB /boot outside LVM, a ~30GB / and ~30GB /home inside LVM. Now I really like spreading things out onto different LV's that I can resize but for now I am focusing on getting /boot and grub2 working. So after the install I did a complete backup with Clonezilla to a spare drive and set to work. I shrunk /home's LV to 10GB to give me plenty of space to work with and created boot_lv inside LVM at 128MB.
So here is my first question:After 2 hours trolling through the forums, documentation and blogs I believe that the ideal size for any /boot is 512MB due to during pre-upgrades Fedora loads a bunch of data to /boot. Would I be correct in both assuming this size and the reasoning behind this?After creating this LV I did another Clonezilla clone of the drive and got back into the Fedora install. From their I moved over all the data in /boot to my boot_lv mounted on /mnt/newboot and unmounted /boot. Then mounted /boot_lv in its place and installed grub2 and gettext ( <--- I think? It needed something like this) and did a grub2-install, grub2-mkconfig and grub2-setup all with commands I do not remember nor documented due to how many changes I have made and times I had to re-image the box from messup's and failures. So in the end can anyone point me in the direction of a nice guide on putting Fedora 14 completely in LVM which seems not to exist in Google and Fedora Forums ( to my knowledge.) Even a set of commands for taking a fresh install and doing.
EDIT: Today I managed to get Debian 6 to have /boot moved into LVM no problem. I documented it very well and plan to implement it on Fedora which I do greatly hope it works.EDIT 2: SUCCESS!!! Took me all weekend to get it working in Fedora but it bloody works! My notes are not the best so I am imaging it right now and am going through step by step again tomorrow and documenting it all on my laptop and writing a tutorial for the Guides section of this forum. It's kinda funny that the only thing holding me back was something rather stupid
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.
I want to load grub2 from grub4dos.I want to load directly the grub2 core. I know how to load first 512 bytes from some patition by chainloader and load grub2, but what I need is to load directly grub2 core without passing by bootstriping code (first 512 bytes).So, my first boot manager is grub4dos, then I can load grub2 and later I load Ubuntu. But I think I have to edit --set-root What I dont know is how.
In hdd 0,7 (sda8) I have Ubuntu 10.10 and /boot/grub/core.img is in sda8 (hd0.7)
I tried this way:
Code: title grub2 find --set-root /boot/grub/core.img kernel /boot/grub/core.img
I have decided to dual boot again because I found a old hard drive laying around.
primary drive: sata 500 gb ubuntu 10.4 64 bit installed with boot
[code]...
secondary drive: 120 gb ide drive with xp installed. xp was installed first and wrote the mbr to sda1. I then installed ubuntu 10.4 and it overwrote mbr on sda with grub2. I have tried every combination of the 40_custom script for xp I have found here on the forums but to no avail. The 30_OS probe never seems to see it either. Grub 2 will not see xp. I have it in the menu from the custom_40 but it just reboots the system when I choose it. Any advice is greatly appreciated as I am ready to go back to legacy grub which only took 5 minutes to dual boot last time I did dual boot. I want to give grub2 a chance, since it supposed to be better, but I am getting frustrated.
Here is the output from the boot info script.
Code:
Boot Info Script 0.55 dated February 15th, 2010 ============================= Boot Info Summary: ============================== => Grub 2 is installed in the MBR of /dev/sda and looks on the same drive in partition #1 for /boot/grub. => Windows is installed in the MBR of /dev/sdb
I posted this about 3 weeks ago in the 'Desktop' forum and with no replies feel this may be a better area
I've got Karmic installed on my netbook which I understand uses Grub2 which is still a BETA version.
I still seem to have the original GRUB (legacy) within the file system, still have a menu.lst file but is appears to be showing the contents of grub.cfg at boot time.
What is happening at boot time, is GRUB Legacy handing over to GRUB2 at boot or is the an option for GRUB2 to hand over to Grub Legacy.
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.
So I recently tried to install Ubuntu Lucid in the following configuration code...
The installation procedure went fine, and it said it had successfully installed GRUB2. But then, when I tried to boot up the fresh system, GRUB2 didn't even load!!
It's not giving me any GRUB errors, or giving me a 'grub recovery>' prompt, so I suspect that it really isn't even booting into GRUB.
I tried booting into the LiveCD, and installing grub to BOTH /dev/sda and /dev/sdb, but it still does not work, and I am at a loss.
Right I had to uninstall windows xp and install windows 7 to play more games! I use windows to play games and that is it. I have restored grub before and I even double checked with this guide: [URL]
I have two hard drives sda - 320gb with windows sdb - 100gb /home -12 gb / -480gb (NTFS) shared
However after reinstalling grub it still boots into windows! I will boot into windows properly then shut it down cos its coming up with windows was not shut down properly and if that doesn't work it has then been shutdown properly and I will install grub again.
I have Win 7 in my hard drive (sda) and I installed Ubuntu 10.04 in other hard disk (a usb disk), but when I try to boot my pc from the usb disk (sdb), the grub shell is displayed. No menu is displayed. When I boot Windows 7 from sda, it runs correctly. The problem it's when i wanna boot Ubuntu. I ran bootscript on the live CD and this is what I've obtained:
Code: Boot Info Script 0.55 dated February 15th, 2010 ============================= Boot Info Summary: ============================== => Windows is installed in the MBR of /dev/sda => Grub 2 is installed in the MBR of /dev/sdb and looks on the same drive in partition #1 for /boot/grub.
After discovering that the "/boot" partition did not end on a cylinder boundary, I booted back up into the alternate cd, re-partitioned everything and re-installed.It worked fine after thatI can't seem to get Grub2 Installed.
GRUB2 won't boot. It hangs just after the 'Boot from CD' thing in my BIOS.I've had 1.97 working on my PC about 24 hours ago, but I decided to start afresh and go for Xubuntu 10.10.I'll post the PC specs in the morning, but in the meantime, does anyone know how to fix this?It's going to be a Xubuntu only system, and I've tried to repair the GRUB files via the Live CD and here.
i know i should look more through the forum, but i've been stuck on installing ubuntu on my computer for 3 days now, reinstalling, manual grub installing and so on, but no go. but i found a good thread on my still no fully functional ubuntu computer that explained very well for a complete linux noob how to install grub2 on ubuntu via the livecd. but since i was booting from the live cd meant that i couldn't bookmark it, and very little on this forum, as far as i can see, gets sticky, makes it very hard to find.
the basic problem is, i completly reinstalled ubuntu 10.10, and the bootloader (that i now know is named grub2) could not be installed. so i've found several guides, including the wiki, but it haven't really worked. now instead of explaining all of this over again, like all of you have probably done a million times, can you just post the most informative links here, so i can pick and choose,
So I have a really old (about 10 years) desktop PC manufactured by Packard Bell, and would like to get Lubuntu 10.10 running on it. I had previously burnt a CD with it, but boot time was incredibly slow on the machine and installation of Lubuntu crashed my system. As a result, I created a LiveUSB (as you do).
When I entered my CMOS, I discovered the BIOS on my machine isn't able to boot from USB, and I wasn't able to find a BIOS update for my AMIBIOS chip on the American Megatrends website. So I booted my GParted Live CD and created an ext4 partition at /dev/sda3, which I proceeded to install GRUB2 onto via the commands:
Code: $ sudo su # mkdir /mnt/grub/ # mount /dev/sda3 /mnt/grub/ # grub-isntall --no-floppy --root-directory=/mnt/grub /dev/sda
This, as planned, succeeded; I can now get into a GRUB2 prompt when my machine boots...! The only problem is, GRUB2 won't detect my USB...or any device other than my hard drive
So, is there any way I can get GRUB2 to find my USB?
P.S. The USB works fine on my laptop, which does support USB booting. I can also boot the USB on my laptop via its GRUB2 command line, using:
Code: grub> set root='(hd1,1)' grub> chainloader +1 grub> boot
Here is my problem. Grub2 outputs error: unknown filesystem. Then when i use "ls" command it outputs this: (hd0), (hd0,4), (hd0,2), (hd1) and when i "ls (hd0,4)/ or any of them it says: error: no such disk
So, heres my story. I dual boot vista and ubuntu from my main 320GB hdd. Today i tried to fresh install 9.10 on a different external hdd. The 500GB hard drive already had two partitions, a 30GB Fat32 and the rest NTFS. both of these partitions had about 17GB used on them. I installed off a cd and i shrunk the NTFS to allow for more partitions. I made a 4gb swap as logical at the end then a primary ext4 / partition in front of it. The drives are Fat32 sdg0, ntfs sdg1, then an sdg3 (which im confused about and says is extension), and sdg4 (with linux) and sdg5 (swap). When finished with the partitions it asked me to select where to mount the ntfs and i said /windows. When i tried to boot up it did not recognize my external apparently because it was plugged in via firewire. I switched to usb and it booted but then i got the error message in grub. Also, when i switched from firewire to usb the drive changed from sdb to sdg. How do i fix this problem? Will reinstalling ubuntu fix this? Is there an easier way? I tried reinstalling grub but it did not work.
I have to do but wanted to check first before I started messing around with my MBR.
Originally was running XP and installed WUBI 9.10 to play around with Ubuntu before doing a proper install. Got home from work tonight and removed WUBI leaving edited MBR with WUBI boot loader. I thought I might have to run fixmbr before installing Ubuntu but I assumed Ubuntu would write over WUBI edited MBR. Installed Ubuntu 9.10 and everything is fine but when I select XP from first boot option (Ububtu) it then takes me to another boot option which was from the WUBI install.
Basically to get to XP, I have to select it twice.
It's not a big issue but I know that this will annoy me and one day or another I will try and remove the second unnecessary option to boot into XP.
So if I have this correct I will need to run fixmbr from XP disc and then install Grub 2.0 from Ubuntu disc somehow?
Is this right? Is there another way I can delete the second boot option screen?
I'm using Ubuntu 9.10 and Windows 7. The problem is I share computer with my brother and sometimes with my girlfriend (but computer is still mine basically).
Now I'd like to set Windows 7 as primary OS, since they don't have much knowledge about computers. When I had Windows XP and Ubuntu 8.04 that wasn't a problem but now I don't know how to do it with GRUB2.
So what I want is s simple explanation how to change GRUB2.
I have 2 hard drives, first drive (hd0) is for data, second drive (hd1) is for the OS's. Windows 7 was installed on (hd1) a few months ago and wiped out GRUB. But today, I decided to go back to Ubuntu. I performed a fresh install of 9.10 x64 to (hd2), GRUB2 works and finds Ubuntu (both the newly installed x64, and the previous x86 versions), but it does not see Windows 7. The only goal I have right now, is to make Windows 7 bootable, once again.
My "sudo fdisk -l" (typing manually, so skipping the Blocks) Device Boot Id System /dev/sdb1 83 Linux -- where x64 9.10 is /dev/sdb2 f W95 Ext'd (LBA) /dev/sdb5 83 Linux -- where x86 9.04 is /dev/sdb6 83 Linux -- /home /dev/sdb7 82 Linux Swap / Solaris /dev/sdb8 87 HPFS/NTFS -- Windows 7
Things I've tried so far: 1) Automatically finding Windows: sudo update-grub2 2) Reinstalling grub via Live CD (9.10): sudo grub-install --root-directory=/media/(where sdb1 - x64 Ubuntu is) /dev/sdb 3) Forgetting Ubuntu altogether and fixing boot using Windows 7 - bootrec.exe /fixmbr; bootrec.exe /rebuildbcd
Now, number 3 is interesting, I found out that where Windows is installed, /dev/sdb8, is a logical partition, and cannot be made active (bootable). This led me to try number 4:
4) Updating /etc/grub.d with custom 40_Win7 file, and making it bootable (the GRUB makeactive, GRUB2 parttool command): echo "Adding Win 7 to Bootloader" >&2 cat << EOF menuentry "Windows 7" { insmod ntfs set root=(hd1,8 ) parttool (hd1,8 ) boot+ chainloader +1 } EOF
When I update grub.cfg after trying #4, it gives me the "not a primary partition" error. So now I am confused. Windows 7 was able to boot previously from this very partition, and I don't think installing 9.10 would change a partition type from primary to logical. So, why can't it boot? More importantly, what can I do to boot Windows 7?
How I can get Chainload into Grub2 to show up as an entry in Grub, I just installed Karmic a week ago on my laptop. I want to set Grub to use this theme. I'm using a netbook, how would I change grub's resolution to 1024x600.
