HOWTO: migrate wubi install to partition

[bcbc]

@WeFY-KVQqr, first off, congrats on being #200

So, this grub problem is still largely a mystery. It doesn't always affect everyone the same way. And I've had installs where it boots fine for a while, but then later stops booting. This latest problem you've found is a new wrinkle... there's nothing wrong with the grub.cfg, but it only shows a partial list of entries. But if you hit 'c' - drop to a grub command line - and manually load grub.cfg (configfile /boot/grub/grub.cfg) you'll probably see it reboot (mine does).

Unfortunately the grub developers have declined to take an interest, so the best we can do is workaround the problem. That permanent fix I describe is to restore the /boot/grub to what it looks like on a fresh Wubi install (prior to any grub-pc updates). This does fix your problem, because - even though you don't have the 'classic' symptoms mentioned in the Wubi megathread, I believe it's still part of the same problem.

Since you can still boot Wubi, you should boot it, go to terminal and apply the fix (those four commands I showed). Then also go into Synaptic and lock packages grub-pc and grub-common (locking is only required if you intend to keep using wubi).

PS I didn't examine your grub.cfg in detail, but in my tests I did compare the before and after - and there was nothing wrong that I could see to explain it. Luckily I was able to reproduce the problem quickly so it makes it easier to diagnose/fix.

Thanks for the feedback
PS I updated post #1 to add it to the known issues.

bcbc, thanks man! It did the trick.
However I had to deviate a little bit from your advise.

The third command

 
sudo cp /boot/grubold /boot/grub

refuses to work because boot/grub has been created in the previous command and after all this command would not make much sense because it boils down to copying the contents of grubold back to boot/grub which is the location where the contents did come from and which would mean no different situation than it was before.
So I've looked it up in the original thread. There I saw this command:

 
sudo cp /boot/grubold/grubenv /boot/grub

and that one does work although I don't quite understand why it works because the original grub folder has a lot of files and after this operation it misses most of them.


This brings me to some other questions:

- There are many updates for Ubuntu 10.04.1 including a new Linux kernel version (2.6.32-28 this time). Is it save to apply them or will they (and especially the new kernel version) once again not make it to the grub menu?
I'm not planning to do this with the wubi installation but only with the new migrated installation.
- Looking back on this complicated business. I rather get rid of the whole wubi stuff after all. Is it safe to perform a regular grub-install command now as pointed out in your first post and will it still be possible to boot into Windows after doing this?

Sorry about that typo - I swear I checked it more than a couple of times
Anyway... that command just copies the grubenv file to the new /boot/grub. That's the same as on a default wubi install.

There's no issue I am aware of with running kernel updates etc. in wubi other than kernel updates automatically regenerate grub.cfg. But since you've made that permanent fix - it has no negative effect - and I'd be surprised if you see that same problem again.

Yes it is safe to install grub2 - you can first boot into the migrated install, run "sudo update-grub" and confirm that it sees the windows install from the output or by looking at /boot/grub/grub.cfg.
Then install it to the drive MBR as described.

using Ubuntu 10.10, I also tried this, I came up with several roadblocks.
When I rebooted I got a grub> prompt only.
after some searching I used my win XP cd to fixmbr and then I got my boot menu back..
however Windows refused to boot and I ultimately wanted to get rid of wubi on the windows partition. I was able to boot to the wubi install or the newly created copy on sda5.
I edited the boot loader and then it only tried to boot into Windows, which it wouldn't, I got a black screen and it locked up.. I said screw that and am cloning it back to the way it was right now..

I assume the Ubuntu will still be on sda5, so my question is, how do I disable wubi without uninstalling it (until I get this working), and how do I go about getting the grub loader to pick up Ubuntu and XP so I can then uninstall wubi.

I am sorry I used wubi now.. nice to tinker with but updates cause unending problems..
If it wasn't such a pain to get my print server working I would just get the data and do a fresh install..

Run the bootinfoscript and post the results. Did you do the manual conversion?

[fubar65]

I used the script, not manual, it seemed to go fairly quickly and it looked like it worked..
I cloned it back and Windows and Wubi are both working now, everything is on sda5 but when I try to update grub and reboot, even windows is gone from the loader, I get several versions of kernel for my wubi install to choose from, nothing more..

thanks for the reply

the biggest reasons for doing this is stability with updates, I don't want slow downs due to fragmentation and wireless has a lot of problems connecting, but I think that is the b43 driver..

I used the script, not manual, it seemed to go fairly quickly and it looked like it worked..
I cloned it back and Windows and Wubi are both working now, everything is on sda5 but when I try to update grub and reboot, even windows is gone from the loader, I get several versions of kernel for my wubi install to choose from, nothing more..

thanks for the reply

I can't see any problems with either the wubi or the migrated install, although it seems like you upgraded your wubi to 10.10 from 10.04.1 - is this correct?
The reason is that you have the 'extended wubi grub menu' and one of the symptoms of this as has recently been discovered is the 'missing' menu items on the Wubi grub menu. (Read back a few posts in this thread).

But this shouldn't affect the normal Ubuntu...

So if I understand you correctly, the migration seemed to go ok, but you ended up at a grub prompt when you rebooted.
You restored back, but now the Windows and migrated install from the Wubi grub menu doesn't show? Is this correct?

First thing I'd do is do the "Permanent Fix" shown (see post 1, known issues, or as described one or two posts back). That should get all your Wubi grub menu entries showing again. Then boot the migrated install from the wubi menu and check it's working fine.

Then try and install the grub2 bootloader again - see if there is any error output from it. Sometimes Grub2 detects the presence of other software using the space between the master boot record and the first partition and outputs a message. In that case, it doesn't always work. But it's hard to know this during the migration as I believe the script suppresses that output (a newer version coming soon handles chroot errors better).

So to do this, boot your migrated install from the Wubi grub menu (after applying that fix) and run:

sudo grub-install /dev/sda

If you see any weird output or errors, then likely it won't boot - so just fix the MBR with lilo before restarting:

sudo apt-get install lilo
sudo lilo -M /dev/sda mbr

or boot from your windows repair disc and just run fixmbr (fixboot not required). If you use lilo, ignore the big warning screen.

If everything looked good, then try booting it again.

how odd, I just booted it up and there it was in the boot menu, the install on sda5..

I did indeed upgrade from 10.04 to 10.10 in the hopes it would fix the long login times to the wireless network.. it didn't help at all.

I am not sure why this showed up in the boot menu but it did..
first thing I did was edit my boot.ini file to remove the wubi reference, then I moved the 2 wubi boot files to another folder, then I ran the sudo update-grub and sudo install-grub /dev/sda

then I rebooted and the proper boot menu showed up, I am now in Ubuntu 10.10 with a true dual boot system, thanks, the guide does work, I just had a few hiccups along the way!

now if I can get the damn wireless to work better I'd be all set..


Th@nX for the guide and info!


edit - I uninstalled the network manager and am just using Wicd and it is working much better, 5 reboots and it logs right in to the wireless!
it's the wife's laptop so she will be happy too, brownie points for me!!

So i figured I would upgrade my wubi 10.04 to 10.10 in the process I found that I will need more disk space as my 30gig wubi just isn't cutting it.

Extending the virtual disk for wubi requires making a larger virtual disk and migrating it over to that. So I figured I might as well just migrate to a real partition.

My upgrade has already started and can not be stopped.

My question is will I be able to migrate a 10.10 version of ubuntu to a actual partition on the physical disk using this script or not?

Also... As it stands the computer has two physical disks. 500 gigs each.

The first disk has windows and a few default partitions from manufacturer.

Second disk has about 150 gigs free and my wubi virtual disk is on this disk.

Is there anyway I can repartion this disk while booted into my wubi install to have 120 gigs for ubuntu and 2 gigs swap.

Sorry i know I asked many questions. I just need to know if these are possible and i will hunt down appropriate threads for the off topic ones.

Thanks!!!!

@Jack-87
Yes you can migrate 10.10 with the script.

No you cannot split a partition while the partition is mounted. You should do it while booted from a live CD. If you don't have an ubuntu cd (or usb) yet you should get one.

It's also a good idea to back up your data, prior to upgrading, prior to partitioning.
