BOOTMGR gone, wont boot to Ubuntu from CD

[BorgCymru]

OK I had Ubuntu 7.10 64 and Vista on this box but Ubuntu started to play up. So I downloaded the newest Ubuntu CD and did another install over the old one. Not formatting the HOME folder or / folder.

Now when I try and boot I see the GRUB but if I select Vista it says BOOTMGR is missing.

I can boot into Vista from the Ubuntu CD but not into Ubuntu. I really don't want to lose my settings on the Ubuntu partition.

Use Super Grub. You can boot Vista, fix its MBR, etc. Then reinstall Grub:

Burn to disk and boot from it.

OK used the Vista repair disk, couldn't make head nore tails of that Supergrub.exe thing.

Now I get

ERROR 22 PARTITION is missing

when I try to boot to Ubuntu.

Windows is not an other-OS-friendly OS. Its bootloader only looks after the related OS. I think when you installed the new Ubuntu, your Grub setup got messed up and the new Grub/new Ubuntu needs to be edited. When you try to boot Vista, your Grub bootloader is not looking after this OS loading so Vista thinks the bootloader for Vista is 'missing.'

I'm just guessing at all this so I advise you to search here for any instances of Vista/Ubuntu dual boots and even Windows (XP, for e.g.) dual booting with Ubuntu.

Boy, I sure do see a lot of instances of this very same problem on these forums !!!

I suppose that is just one of the reasons that I don't use M/S windows.

BUT after all this time, you would think someone would have come up with a solution to this problem !!!

And I know Ubuntu can't control what Windows does but it looks like to me if they know what it is doing, they could fix Ubuntu to work its way around the problem.

[Pumalite]

Read Super Grub's Documentation. It can do just about everything for you if you learn to use it.

[BorgCymru]

Vista is working fine, its the Ubuntu that has the problems. It says it's not there. or hiding. I really want to update it from the live CD so I don't lose my info and stuff. How can I do that now ?

[SeePU]

Doesn't that mean your grub entry is messed up? You have to re-edit your menu.1st file and put in your new Ubuntu install location? Your new install probably over-wrote your previous file?

Someone else should recognize the problem. I'm just learning so I will know how to partition and use grub. I want to have around 4 or 5 operating systems ultimately so I'm trying to learn a lot about grub etc.

Boot your Live CD and post:
sudo fdisk -lu

[BorgCymru]

I've just done another install of Ubuntu, and I still get the error 22 . This time I DID format the / partition. Still wont load from GRUB or live CD boot for first HDD options.

[Pumalite]

Boot your Live CD and post the command I gave you.

Edit menu.lst and change 'groot' and 'root' of Ubuntu to (hd0,1)

[BorgCymru]

how do I do that through the live CD ?

Thanks

sudo nano /media/sda2/boot/grub/menu.lst

Reboot.

[BorgCymru]

Ahh here might be the problem. that file is blank

[Pumalite]

It cannot be blank. You just post it.Review your commands. Copy and paste in the Terminal.

[BorgCymru]

Thats exactly what I did and it came up as NEW DOCUMENT

I thought it was very strange seeing as I had posted the contents before.

[Pumalite]

sudo mount -t ext3 /dev/sda2 /media/sda2
Enter
now try again.

[BorgCymru]

ubuntu@ubuntu:~$ sudo mount -t ext3 /dev/sda2 /media/sda2

[BorgCymru]

Sorry for slow reply.

OK after getting nothing I re ran the first lot of code you said.


ubuntu@ubuntu:~$ sudo fdisk -lu


I noticed that it now said HDa instead of SDa. So following the instructions but using hda I can now boot into Ubuntu.

BUT

I can no longer see my home partition.

Post:
df -h
mount

Tried a new instal again still getting ERROR 22 now again :(

I'm going to re partition the whole drive I think, seems its got a bit messed up. I'll get another drive to back things up and start again.

[Pumalite]

Good luck.

Thanks :)
