Ubuntu :: 10.04.01 And Win7 - No Grub Menu Pops Up
Oct 12, 2010
I finally got it and windows 7 installed on separate hard drives. Windows installed first, then ubuntu 10.04.01. Had to use the alternate ubuntu install cd to make it work. During the install it said there were no other operating systems installed on the computer and asked if grub could overwrite the master boor record. I knew this was something I wanted to do and if it was wrong it could most likely be fixed later. So that being said, ubuntu has taken over the boot of my pc. No grub menu pops up. Not sure how to add windows to grub to make it give me a choice. I did try pressing shift during startup to get grub to load, and nothing happened.
Here is my fdisk.
Windows is on sda and ubuntu is on sdb.

My machine is an hp 2133 mininote. It came factory installed with Windows vista, which repeadtedly crashed on me. To compenstate for this i installed gOS to dual boot with Vista. This was working fine but I was recently given a Windows 7 install disk, so I decided to upgrade. Windows seven installed without a problem but now I can't access the GRUB bootloader, windows 7 just loads automatically. I tried to restore it using the Super GRUB Disk usb utility but it didn't work, windows 7 still boots regardless.

I have Opensuse 11.2 installed (on hd0 at the time of installation) To install Windows 7 alongside I had to switch my hard drives (hd0 became hd1 and vice versa) What is the best approach to reinstall grub and get both Opensuse and Win7 visible in the grub menu?

Just installed Ubuntu 10.10 onto my new netbook from a USB stick. The laptop came with Win7 Starter, which I kept on a small partition. Installation was apparently successful, but when I start up the computer, it will go straight to Win7 and GRUB doesn't appear.

I am testing my crash recovery strategy for my linux system and I am having trouble with GRUB. I am basically restoring my backup (i.e. tar) unto a different hard drive, but I am having problems getting the machine to boot without me having to type the GRUB commands at the GRUB prompt that is presented when the machine boots up off the new hard drive. I have tried to restore the MBR in two ways (the 2nd one is the one that gets me to the GRUB prompt):
1. Get the MBR off the original drive and write it unto the new drive (all via dd), but that did not work at all: the machine hangs right away during boot up. It seems to hang right at the point where the BIOS tries to read the MBR.
Code:
On original drive:
# dd if=/dev/sda of=mbr+part.bin bs=512 count=1
On new drive (new drive is now in place of original drive):
# dd if=mbr+part.bin of=/dev/sda bs=1 count=446 conv=notrunc
2. By using the FEDORA rescue CD, I installed grub unto the new hard drive as follows:
Code:
# chroot /mnt/sysimage
# grub-install --root-directory=/boot hd0
reboot and remove FEDORA CD Using the 2nd option above, I get the GRUB> prompt during bootup. I can then boot into the system by issuing the commands that are in the menu.lst file, followed by the "boot" command. However, I would like for those commands to happen automatically, just like in the original configuration. It seems to me that GRUB is actually finding all its stage files because I doubt the GRUB program (the one displaying the prompt) fits entirely in the 446 bytes it has on the MBR. So, it must be loading its stage 2 (and stage 1.5??) files from my /boot partition. However, if GRUB is loading its stage files off the boot partition, why does it not load/read the menu.lst/grub.conf contained in the boot partition also?
Code:
# ls -l /boot
total 22888
-rw-r--r--. 1 root root 1274567 2009-05-27 16:39 System.map-2.6.29.4-167.fc11.i686.PAE

I have 2 hard disks. sda,sdb
In sda, I have 4 partitions, and I have windows 7 in one of the extended partitions [not in the primary partition].
In sdb, I have 3 partitions. 2 for storage, and 1 10GB drive for Ubuntu. Again, Ubuntu is not of a primary partition.
I had ubuntu 10.04 running on that for a long time. However, I wanted to reinstall ubuntu and use 10.10.This is what I did EXACTLY:Booted from Ubuntu install CD
Chose advanced istall
Selected sdb3 for Ubuntu
I installed GRUB2 on the SAME partition as Ubuntu aka sdb3 Installed then rebooted
I can boot into Ubuntu fine, but whenever I select Windows 7 bootloader from the GRUB menu, the screen goes black, and my PC reboots.
Boot Info:
Code:

my Setup is Fedora 14 x64 + radeon hd 4830 i've downloaded .run package from ati site with latest driver for x64 systems. installed it, but didn't edited grub.conf becouse i didn't understood anything there (probably didn't spent enough time to get things understand) Now i've lost possibility to enter my Fedora system. during boot it lost it's modern blue boot screen (with filling drop), it was replaced by standard old boot screen with triple-color stripe. after this boot screen monitor start blinking going on and off. and on last step i'm getting "Fedora 14 boot bla bla bla something" on screen. nothing works except Ctrl+Alt+Delete. system reboots showing successful daemons shutting sequence. How can i edit grub menu from initial grub screen is it possible to it's own 'e' option or 'c' from grub command line?

I installed Win7 on a 2-disk RAID0 fakeraid. I then unplugged those drives and installed linux mint on a separate drive. I did it this way because if I left the drives plugged in, linux would jack up the fakeraid for those drives and make windows upbootable, and installing linux to the fakeraid itself is just too much of a PITA. So basically, this is the disk configuration, and there's no chance of me changing it.
Right now, I can boot into either win7 or mint by pressing F12 for the boot menu, and then selecting the drive the os is installed on. It would be nice if I could just add an entry to the grub menu for win7. I've used the menu.lst file before, but apparently all that has changed with grub2. I've checked out some of the grub2 docs and poked around in /etc/grub.d, but frankly, it seems to be orders of magnitude more complicated than it should be.

I had a win7 installed on my system first. Then I installed Ubuntu and added grub2 boot option with win7 utility program EasyBSD. But then I accidently deleted win7 boot option from windows loader menu. Now I can only chose to load Ubuntu. How can I restore Win7 loading option? I have Win7 option in grub2 but it returns me to the previous screen, from which I have deleted win7.

9.10 has no menu.lst file and hitting ESC to does not bring up the grub menu. How can we set bootup options or boot an alternate kernel? I would really like to set the resolution at boot time so that my console (Ctrl-Alt-F5, for example) has 80 columns instead of 40. (What a stupid default, gigantic Commodore-64-like text!) It would also be nice if the Login screen could be set to the resolution that I want.
In previous releases, there were ways to do this. In 9.10, I haven't been able to figure out how.
Is there a document explaining all of the radical changes?

I just upgraded to 10.04 from 9.10 and when I choose to boot to my Win7 Pro it just loops back to the grub menu. I did choose the partition that Windows is on when I was upgrading and it shows up in the menu.

I updated Ubuntu and part of it was an update to grub. When it came up in the installation I told it to keep the old one and left everything as it was. Then when I tried to reboot into Windows it gave an error message. So I went back into Ubuntu and reinstalled grub and now when I select Windows it just loops back to grub.

I got ubuntu 10.04 lucid lynx along with windows (dual boot) and using Grub. On my computer, I have my C:/ (programs) and D:/ (data). I've never used my D:/ before that day that I've lost my windows partition on my grub menu. I usually use my D:/ with windows. The first time I used my D:/ to store data with linux, I lost my windows option in my grub menu. I'm not sure what I did wrong but I do want to restore my windows option in my grub menu.
After "fdisk -l",
I checked in /boot/grub and there is no menu.lst to modify. how I can get back my windows option in my grub menu ?

The first is I seem to have 3 GRUB installs. So whilst I update the one from my live session, the change does not appear in the boot up menu. I had installed 10.10 from a CD into a different partition (sda6), but that will not boot, so I have just deleted this and done another grub install and update. The kernel I am using has just been updated from 10.04 to 10.10 too, and it is this that I use and the Grub I have been working on (sda5).

Last night, I formatted my laptop(Asus w5f). And I installed win7 Home Premium. Then I installed Ubuntu 10.04. After installation, I restarted the computer. When I choose win7 at grub, comp. restarted itself. But When I choose Ubuntu, started properly. Now, grub is not starting win7. At ubuntu, I can see windows disk and files. But win7 doesn't start.

I set up a dual boot system with Win7 and Ubuntu 9.10. Ubuntu is the first OS listed in the boot menu. I would like to change the boot order so Windows is first. Also after running a few updates I now have multiple boot items listed for Ubuntu that I'm sure are no longer needed. Having never edited Grub and searching through the forum, I'm asking help. I going to guess that I want to edit grub.cfg. If so, what do I need to change within the following information?

Looks like Grub2 on my new installation of Ubuntu 9.10 is not picking up a Windows 7 installation on a RAID0 array (using the built-in RAID software from my Asus P5Q-Deluxe)
Here are the results of the boot info script:

I had XP Home on my dual boot Ubuntu 10.04 LTS amd64 PC & now installed Window 7 Home Premium 64-bit over old XP. Before installing Win7, as a precaution, I disconnected the hard drive where Ubuntu is installed. Now, naturally, the startup screen (grub?) still offers XP. Is there an easy way to re-detect & rewrite the startup menu with the Ubuntu install CD without re-installing Ubuntu 10.04 LTS amd64 again, like a GRUB repair or rewrite?

I have a major problem with Windows 7's MBR. I deleted Ubuntu's partition last night, and when I restarted, I saw:
Code:
error: no such partition
grub rescue>
I looked it up, put some code into a LiveCD terminal, and I thought it worked. But now, I says that I definitely need to put in a Windows 7 CD and do that MBR fix method. I did not own a Windows 7 CD; my laptop came with it pre-installed, and I have no recovery partition anymore.

My tech savvy friends built me a computer and put win7 64 bit and then installed ubuntu (upgraded to 10.10) and had grub so whenever i turned my computer on i could choose between linux and windows and everything was fine. The other day i couldn't boot into ubuntu so i went into my win7 partition and deleted ubuntu and all other partitions and/or extensions thinking that it would get rid of ubuntu. Now when i boot it doesnt recognize anything so i tried booting from my ubuntu cd (don't know if its 10.4 or version) and it will load and when i try to install it i get the grub recovery thing and then the initramfs thing and the error "initramfs Can not mount /dev/loop0 (/live/image/live/filesystem.squashfs)"
i don't need ubuntu but i do need windows as it has files and papers that i need this week.

I've resized partitions with some program - perhaps even gparted - but from Win7. partitions are indeed resized, but now I can't boot Win7, grub says:
"No such device found - No such partition found".
I tried to use some advices on similar problems I found here (like adding GRUB_PRELOAD_MODULES="part_msdos" to etc/default/grub and running grub-mkconfig after), but nothing helped. I guess I could restore win7 with installation dvd but I want to fix GRUB (and have both ubuntu 10.10 and win7)
