GRUB doesn't recognize ubuntu or windows XP for dual boot


Sorry this post is a bit long, but I'm going to try and be as descriptive as I can:

I just installed Ubuntu Intrepid 8.10 on my brand new Lenovo Thinkpad T400. It came with a 200 GB hdd partitioned into two primary partitions: one for windows and one for recovery of the OS software. I wanted to keep this recovery partition so I was told to install GRUB into a third primary partition /boot (I assume that means that when you're in the partition editing utility on the Live CD you simply create a primary partition in ext3 format, give it about 100 MB, and mount it as /boot...but correct me if I'm wrong). Anyway, I did this, selecting the option to have GRUB installed in /dev/sda3 which was mounted as /boot. I believe this was meant to prevent overwriting the master boot record.

Anyway, after repartitioning I installed Ubuntu and rebooted, and the boot sequence took me directly into Windows XP (SP2), which I was told would happen. So far so good; I was feeling pretty good about the install. I went into the administrative tools section of Windows and changed the active partition to be sda3 (the partition I mounted as /boot), and this is where things got a bit confusing. Windows recognized the other primary partitions on the hdd, but for this partition that I had designated as /boot (and I'm 100% positive I specified "primary" when I created it, as I double and triple checked everything) it said that the partition type was "Unknown." Anyway, being absolutely certain that I had made it a "primary" partition, I figured Windows just didn't know how to recognize it for whatever reason, and I went ahead and made it the active partition.

Now when I boot, I must be going into the /boot partition because I see that GRUB loads, however it takes me directly to a command-prompt-type interface and there is no list of operating systems on my computer as I thought there should be. The screen simply reads:

[ Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists the possible completions of a device/filename. ]

grub>

I'm not sure what went wrong here. I know that when I resized my Windows partition it worked properly because I got Windows to boot, but then on changing the active drive partition I just went straight to this interesting GRUB command line. Now I'm not sure how to change the active disk partition back to my original one since I can't get back to a DOS prompt in Windows (since I can't boot either of the OS's on my system now).

Is there something I need to do to configure GRUB properly since it seems like it's merely missing some kind of pointer to the two OS's? Should I try repartitioning my hdd and reinstalling Ubuntu? And if I need to reinstall and the name of the partition in which GRUB is installed changes, how do I switch the active partition to that new one?

Any help you could provide would be much appreciated.
Thanks in advance!

can I suggest you either change it back to normal first partition and mod your windows to chainload grub
and I assume you correctly put grub into sda3....or

boot up the live linux cd and put grub into mbr....yep you lose xp bootloader links

edit the linux menu to have a chainloader for xp

see my signature for both ways

but yours for linux will be

title windows
root (hd0,0)
makeactive
chainloader +1

I'm surprised you got as far as you did - go here and post the file this creates. Can be done from a liveCD.

Windows generally won't recognize a Linux partition.
Creating a separate /boot partition isn't necessary but, if you want to do it the link below explains in detail how to on Ubuntu:

http://users.bigpond.net.au/hermanzo...boot_partition

You mentioned your two windows primary partitions and the sda3 for /boot. Did you create an sda4 to put Ubuntu on?

No, that's not the reason. Read the link aabove for details.
You also don't need Ubuntu on a partition that is set as active nor does it need to be on a primary partition. I expect that after your first re-boot when it went to windows, you had not installed Grub stage1 to the mbr and after the second re-boot you had but don't have the pointer correctly set. Read the link above, should be helpful and also post the output of the file syg00 suggested as it gives a lot of detailed info.

Yes, I created an extended partition (I assume that's the sda4 that doesn't show up in gparted, but houses sda5-8). I wrote down the details, listed below:

sda1 ntfs 120005 primary
sda2 fat32 6288 primary
sda3 ext3 /boot 98 primary
sda5 ext3 / 10001 logical (I assume Ubuntu automatically installs here?)
sda6 ext3 /home 10001 logical
sda7 swap 3997 logical
sda8 ext3 /data 49647 logical

The partition editor in the live cd makes an extended partion automatically if you select the "logical" option (there is no "extended" option, but I read in the Ubuntu documentation that it lumps logicals into an extended partition "automatically").

I do have a set of CD's that I made when I first got my laptop, that I believe contain the contents of the service partition. Thinkvantage had a utility that allowed me to write the OS to 3 DVD's as a backup, one of which is bootable. Other than that, I have virtually no data on the computer as it is brand new, so I'm not worried about backing up.

I'll try running the programs some of you mentioned and listing the output later, but I'm off to class now. Thanks for the replies, I'll reply back later this afternoon.

How do I run the BootInfoScript file you referred me to if I can't get on the internet? My wireless doesn't seem to be working when using the Live
CD. Does it come with the Ubuntu distribution? I do have access to a desktop also with an internet connection, by the way.

Also, am I correct in assuming the specifying a mount point for my partitions in the partition editor on the Live CD is the same as giving them a name? I mounted a /data partition as a logical inside my extended partition which contains the / partition and the Ubuntu install. Will this simply show up as a /data drive on the system or will Ubuntu just not know what to do with it since it wasn't one of the standard mount options??

Use the Live CD. Open a terminal window. Type: sudo fdisk -l (lower case letter L) and post the output.

In the terminal window type: sudo mkdir /mnt/ubuntu
sudo mount -t ext3 /dev/sda5 /mnt/ubuntu
cd /mnt/ubuntu
ls -l

after the last command you should see a list of directories and you will know if your installation succeeded.

to see if your boot files are there do:

sudo mkdir /mnt/boot
sudo mount -t ext3 /dev/sda3 /mnt/boot
cd /mnt/boot
ls -l

to see if your boot files are there.

If you want a separate boot partition, I would suggest some detailed reading of the site I referred you to earlier. Very good info on Ubuntu. Also, if you have your computer setup with separate /boot, root and /home partitions you will have to tell the installer where to install everything.

It's a script - download it to a USBkey; put the resulting txt file there too. Post the results from any machine with a connection.

I have downloaded the bootinfoscript file, but can't run it. I tried saving it to the desktop and running, but I don't know how to navigate to my desktop in the terminal. Ubuntu won't let me save it to another directory either...

I also noticed that in my grub directory, there is no grub.conf file. I tried making one myself, but I didn't have the permissions to save it to the grub directory. I don't know what's going on, but I think it must have something to do with using the Live CD.

Bmosov01, once you have the Boot Info Script on your Ubuntu desktop, just do the following from the terminal:
Code:
sudo bash ~/Desktop/boot_info_script*.sh
That will create a "RESULTS.txt" file in the same directory from where the script is run, namely your desktop; how about copying/pasting the contents of that file to your next post, highlight the copied text, and click the pound sign # graphic in the forum message box so that the text will get "code" tags put around it. The results of that script will help clarify your setup and hopefully what your booting problem might be.

Hi syg00...thanks for the script idea.

I like to state the obvious.

sda2 is the bootable partition as appears to be where boot is...but I have not asked him to read my troubleshooter as yet...to confirm that.....as the script says so

now the only question is....does the OP want to use windows to chainload to the bootloader in root of sda2 or install grub to mbr and use grub to chainload to bootloader at root of sda1?

I guess it might be easiest to just install GRUB to the mbr. This whole problem kind of came about because I was trying to avoid that, but at this point I'd just like to get this *%@# thing working. I know there is a command line option in the grub shell to install it to the mbr, so maybe I should just try that?

Bmosov01, please don't think that you are being "dense", after all, we all start out as newbies to Linux at some point; so I totally understand these things are not obvious in the beginning (especially if you come from using Windows), or at least they weren't for me either.

It looks like the only problem is that the Grub installed to the boot sector of your sda2 boot partition is for some reason pointing to the sda3 partition for Grub's menu.lst file, when Grub should be pointing to your sda2 boot partition for the menu.lst; that would explain why you get dumped into the Grub command line on start up, because Grub can't find the menu.lst. How about trying the following:
Code:
sudo grub
grub> root (hd0,1)
grub> setup (hd0,1)
grub> quit
And please post the output of the commands before doing "quit." The above commands will reinstall Grub to the boot sector of your sda2 partition and hopefully correct the problem. Next reboot, and let us know exactly what happens on start up. We can work from there if you want.
