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.
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.
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 I tried to create my own menu entry for Windows XP but it seamed to me that it was superseded by the Windows 7 boot loader.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I don't know how to bring back a menu entry that was over written / Superseded by another OS being detected by update-grub; in this case Windows 7.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 Windows XP didn't boot any more because it was replaced / Superseded.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 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.
I 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)
root (hd0,4)
kernel /boot/xen.gz-2.6.18-194.17.4.el5
module /boot/vmlinuz-2.6.18-194.17.4.el5xen ro root=LABEL=/1 rhgb quiet
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 RelatedThey finally got the MCP89 kernel patch finalized and released as a Ubuntu DVD in the daily build of Lucid Lynx (good job!). I tried it, but even after following Ubuntu's Wiki-guide to fix various problems, a lot of my Mac's functionality broke and I don't want to take up that battle yet (of trying to get everything to work perfectly {I'm a perfectionist}).So I want to remove Ubuntu and GRUB2 from my system. But even with some experience with problems like these, I'm in the ultimate pickle. OS X uses the GUID Partition scheme and EFI, whilst bootcamp has a BIOS/MBR emulator to run Windows. I installed the GRUB bootloader to the MBR (I think {In "/dev/sda" during the install}). I use rEFIt to chainload into GRUB2 to boot Ubuntu, and I want to remove that icon, return to booting Windows 7 using it's own bootloader, and restore the GB's that Ubuntu took back to the Windows 7 partition.
I'm lost and (for the first time in a while) WAY over my head. I have no experience with EFI/GUID. (I just got my first Mac a month ago)
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)?
View 2 Replies View RelatedI am actually facing a vague problem here. I was previously running Windows XP and Ubuntu . Ubuntu was installed Windows XP The problem is
1. First I tried to do some disk partitioning. That ended up with some error.
2. Ignoring that, I went to install Windows 7 over Windows XP but I was not able to proceed with Windows 7 , because the partitions were corrupted.
3. So I used Ubuntu LIVE CD (Grub was lost at this point )and used 'testdisk' and recovered the partitions.
4. Now installed the Windows 7 successfully.
5. Now again I moved to Ubuntu Live CD to write the GRUB. After which I tried restarting
6. Now Ubuntu is booting perfectly as before. But the problem is with Windows
7. The GRUB loader instead of showing Windows 7, it shows Windows XP !!! . and there is no other entry for windows. When I tried opening it, it says "error, cant read file" and further inout moves back to the grub loader list again.
"How do I change the entry to Windows 7 from Windows XP and boot Windows7 successfully " I tried it a couple of times, same thing happens . So how to change the entry?
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?
So I have my netbook triple-booted with Windows XP, vanilla Ubuntu, and Kubuntu Netbook (Installed in that order).
I however would love to remove Kubuntu Netbook from my computer, but unfortunately, since I installed it last, it is the Linux OS that owns the current default GRUB files that the BIOS reads first.
Can someone please tell me what to do to remove the Kubuntu partition and restore the default GRUB to my vanilla Ubuntu so I can still use my computer? I've done this incorrectly before and freaked myself out because whilst trying to access the GRUB, my computer couldn't find it because the partition that the files were originally on was gone. Haha. I don't even know how it got fixed.
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 3 Replies View RelatedI currently dual boot and wish to know how to remove the Windows partition/drive while still allowing Ubuntu 9.04 to load safely as my main OS. I know how to restore windows partition by;
If MBR gets damaged boot from MS Windows Xp disc, Select "R" for "recovery console", select main windows installation drive (admin password usually nothing, just press enter) and type "FIXMBR" this will allow you to boot windows again, but Ubuntu partition will be unbootable and require installing ubuntu again to dual boot.
But this leaves Ubuntu partition Un-bootable as it removes the grub menu, how would I do the same for Ubuntu and make window partition un-bootable so I can remove it?
Ubuntu's update manager recently updated the Grub menu.lst file. It let me decide if I wanted to keep my old menu.lst or the new one. After deciding that I was fine with the new one, I found out that I can no longer boot into Windows 7. I had previously edited menu.lst so that Windows would be at the top of the list, however, I didn't notice that this had put it into the automagic update area, and I realize now that I should have just edited what the default number was instead of moving around the entries.
Anyways, I can no longer access my Windows 7 OS via Grub, and I was wondering what sort of fix I can have for this. I've tried running update-grub, but it hasn't fixed the problem. The Windows bootloader is on the first partition of the only hard drive, as far as I can remember.
I need to remove an entry from my grub boot loader does anyone have a simple way to do this?
View 6 Replies View RelatedI 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?
I have windows 7 in RAID 0 and installed Ubuntu 9.10 to another Sata drive. Ubuntu is working fine but if I try to boot windows in the Grub2 loader it goes do error and lets my to restart. I have finish the windows system recovery and setup repair several times and it won't find any problems. I can't get to windows loader.

I have a asus eeepc 1101ha. With Karmic,it would boot into w7 without problems.I installed Lucid on another partition,and after that the w7 grub entry would leave me with a blinking cursor in the left top corner, and hang.
I booted with the w7 dvd, ran bootrec.exe to restore mbr and bootmgr, and the booted into w7 to confirm. It was working. Then I booted with the live dvd, mounted the lucid partition, and installed grub. Now choosing the w7 entry would ask for the boot media, and pressing any key would bring me back to the grub menu. Lucid and karmic boot without problems.
Installing grub from karmic now gave the same error. Running update-grub didn't change anything.As I had to use w7, I booted again from the dvd, and restored again mbr and bootmgr. Booted into w7, used it, then once again to the live cd, to reinstall grub, and once again the w7 entry in grub makes grub ask for the boot media.I've attached my boot info script.Ah, I also played with the bootable flag for the /dev/sda1 partition, but it didn't change anything.
After installing ubuntu 10.4 netbook remix edition to my laptop, I then found that GRUB hadn't installed at all, and it went straight to windows 7 each time. So I rebooted from my live-usb and got into the terminal, and typed
Code:
sudo grub-install /dev/sda5
Which then gives me
Code:
No path or device is specified.
Try `/usr/sbin/grub-probe --help' for more information.
Auto-detection of a filesystem module failed.
Please specify the module with the option `--modules' explicitly.
menuentry "Windows 7 (loader) (on /dev/sda1)" {

insmod ntfs
set root='(hd0,msdos1)'
search --no-floppy --fs-uuid --set 3850d16450d12980
chainloader +1
}
This is automaticly genarated after installed ubuntu 10.10. It shows black screen with a flashing cursor after press enter. Grub 0.97 also does this with:
title win7
fallback 2
find --set-root --ignore-floppies /bootmgr
chainloader /bootmgr

But the wierd thing is my usb stick can boot windows 7 succesfully with the same configuration. Whats wrong with that? How can do with grub.cfg?
ok so sounds like everyone elses issue that i`ve seen on here but i had it all working properly until i booted into ubuntu and updated grub somehow and when it told me to reboot all i got was a grub rescue error.
Now i got ubuntu 10.10 installed to try and fix the grub 2 error but now cant get it to boot windows from the menu.
i was dual booting windows 7 and ubuntu 10.04 with grub2 as the boot loader then I had to reinstall windows because of some issues, during the installation I had to DELETE the partition windows was installed on then create a new one, this was the ONLY Primary partition in the hd and it was the partition grub2 installed on.
After the installation finished, i loaded an ubuntu live cd and reinstalled grub2 using the graphical tool "boot-repair", it worked and windows 7 appears on the list but ubuntu does not!. I tried sudo update-grub2 (found a tutorial to make this command work in Live CD) but the problem still exists. I also tried booting using the command line (set root=(hd0,1)....etc) but it doesn't work, windows boots when the value is set to 1 but when I try 2 I get an error.
Is there a way to verify that the ubuntu installation is still working and how can I make it appear on grub2 if it's still working. As I said the deleted windows partition was the only Primary partition and the / & /boot & /home & swap were all logical, do I need to set / partition to be Primary in the installation?

Is it possible to remove the entry 'Other operating systems' from the Grub menu display? I mean that it can be commented in menu.lst,but will it affect other OS(Win XP in my case) in any way?
