    Okay, I took you literally when you said you couldn't even boot from the live CD.

    So I'm curious how Wubi manages to run if Ubuntu cannot see your disks? Did you install it to an external drive? Why don't you download and run the bootinfoscript - that should be easier to figure out what's going on.

    Again my sincere thanks for all your kind assistance. If you find a sure fire way of fixing the problem then all well and good.

    I had a look at using a USB pen drive but it did not work as expected. It might be down to the fact that I have messed about with the drive doing various things and letting others have it to use. I am going to get a new pen drive and follow the instructions on the Ubuntu.com download page.

    Wish me luck.

    Again thanks
    If you are here to drink to forget please pay in advance.

    Intel Dual Core T2390 1.86Ghz; Intel GMA x 3100 graphics, Atheros AR242x802.11 a/b/g. 1GB RAM.

    Well, I made a USBmultiboot with Multisystem app and a cd-boot-liveusb.iso CD and so I could try a bit 11.04 live and check with GParted and the Disk Utility what I told you about Ubuntu not seeing my RAID structure. But this is the first time I succeed booting from a live device!

    Anyway, back to my 10.04 Wubi, here is my Results.txt:

    As the Wubi installation is within Vista, it is a matter of Windows to manage the RAID disks, I guess.

    Actually the same installer is used for both Wubi as well as normal Ubuntu (it's called ubiquity). Wubi just does some additional work to create the virtual disk, setup a custom boot mechanism, and create some 'preseed' instructions so that Ubiquity doesn't prompt you during the install process.
    In other words, if you can install Wubi on a RAID then you should be able to install Ubuntu.

    Interestingly you have two /boot directories as well:
    /boot/grub/grub.cfg /Boot/BCD
    This has been reported to cause problems with Windows.
    Also your Wubi grub.cfg looks like it could cause the Problem #2 described in the first post of this thread - so you might want to apply the "Permanent fix" there before it stops booting.

    So, why, when being with the 11.04 live USB, Ubuntu did not seem to see the RAID? Is there any instruction from within 11.04 live that could offer a picture of what it actually sees (I mean the RAID)?

    I am in 10.04.2 Wubi, so I guess I should apply first the Solution #1 and then the Permanent Fix; as Solutions #2 and #3 seem to be for upgrades to 10.10.
    I suppose it is capital to follow the right procedure to have a 100% clean Ubuntu boot. In my case, I always succeed in booting Ubuntu (in fact, I nearly never boot Windows), though I must admit that it is not a very clean one.

    Well the bootinfoscript seemed to identify the raid correctly. That's running under Ubuntu. Wubi is the same as Ubuntu: it boots natively (the main difference being the virtual disk) - and Wubi could not run if Ubuntu didn't see the root.disk on the raid.

    So, I'm no raid expert - but it looks like Ubuntu can see it fine.

    Solution #1 (and 2 and 3) are only when you cannot boot the Wubi install. Since you can boot it, you can proceed to the Permanent Fix.

    So, I guess that I'll first go and "clean" my Vista disks from within Vista itself, by allocating space for a new partition (the native Linux one(s): swap + boot + home) and then proceed to install Ubuntu from the USB live.

    Solution #1 (and 2 and 3) are only when you cannot boot the Wubi install. Since you can boot it, you can proceed to the Permanent Fix.
    OK. Thanks

    Re: Wubi megathread - Taking long time to Boot

    I'm posting this new query as a new reply because I don't see a button for a new question.

    I have installed ubuntu 11.04 32 bit within Win 7 using WUBI.

    At the time of booting, first it presents the choice of OS to choose from & then, when I choose ubuntu, it displays hd(0,0), no wubildr & the cursor goes on blinking for nearly one minute. Then, hd(0,1)is displayed & the rest of the booting process is completed normally.

    I think this is because hd(0,0)doesn't exist in the new numbering system. How to correct this anomaly so that booting occurs quickly without the initial delay?

    Re: Wubi megathread

    ssreddy555,
    Wubi uses grub4dos to search for the Wubi partition and boots it when found. Although this is perhaps annoying it is normal. I am not aware of a direct fix for this.

    Re: Wubi megathread

    Thank u.

    I was rearranging partitions to migrate ubuntu to partition from WUBI. In the process, somehow, it got corrected itself. It is now going directly to GRUB, without delay after we choose the OS.

    Coming to the issue of migration, I created sda 5 of about 45GB & a small sda 6 of about 1.5 GB for swap as detailed in this thread:
    http://ubuntuforums.org/showthread.php?t=1519354. This is in addition to sda 1, 2 & 3, where Windows 7 is installed.

    When I tried to execute the command for "migration with swap file" in the Terminal, as detailed in the above thread,It says sda 6 is not a swap partition. What does it mean? All the sda's are NTFS formatted.
