@bcbc thanks a lot - everything worked perfectly.

You're welcome. Enjoy!

Ubuntered,

Try using Solution 1 for Problem 2, which mounts the root.disk and then edits the grub.cfg file.

Thanks for the quick reply. I've actually already tried that fix and it didn't work, it will probably work if I can figure out the correct dir. path, but I'm gonna need help for that. Keep in mind I'm new to linux. Here's the results I get. Thanks for the help

ubuntu@ubuntu:~$ sudo mkdir /media/win
ubuntu@ubuntu:~$ sudo mount /dev/sda1 /media/win
ubuntu@ubuntu:~$ sudo mount -o loop /media/win/ubuntu/disks/root.disk /mnt
Killed
ubuntu@ubuntu:~$ sudo cp /mnt/boot/grub/grub.cfg /mnt/boot/grub/grub.cfg.copy
cp: cannot stat `/mnt/boot/grub/grub.cfg': No such file or directory

Here's the Boot Info Summary

First backup the root.disk if possible.

Then try:

sudo mkdir /media/win
sudo mount /dev/sda1 /media/win
sudo fsck /media/win/ubuntu/disks/root.disk

Then (if that doesn't give you errors),

sudo mount -o loop /media/win/ubuntu/disks/root.disk /mnt

If that works - then continue with the rest of the instructions.

Actually I might run chkdsk on your Windows C: drive as well before running fsck.

Thanks, I'll give that a try, booting into window's now to run chkdsk on C:, I also have a backup of root.dsk just in case. I guess if all else fails I can always uninstall via wubi, then reinstall via wubi to fix boot problem and then replace my root.dsk with backup to get all my settings and programs back, I think that would work but I'm not sure. Thanks for your help, you guys are awesome!

Copying the root.disk back over will work. That's a convenient way to backup your Wubi install.
But backing it up after you are having problems won't help if the problem is on the root.disk itself. It's still a good idea to take a backup before attempting repairs e.g. running fsck

Alright, here's the results, looks like I might have some file corruption or something. Thanks again for all the help.

ubuntu@ubuntu:~$ sudo mkdir /media/win
ubuntu@ubuntu:~$ sudo mount /dev/sda1 /media/win
ubuntu@ubuntu:~$ sudo fsck /media/win/ubuntu/disks/root.dsk
fsck from util-linux-ng 2.17.2
e2fsck 1.41.12 (17-May-2010)
fsck.ext2: No such file or directory while trying to open /media/win/ubuntu/disks/root.dsk

The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>

I'm not sure if this is relevant, but when I created the partitions, (which I did with a linux live cd - ubuntu 10.04) I chose a ext4 (or something similar, not exactly sure) file system for the linux partition, however I later used windows disk manager to alter the partition to ntfs so I could see it from windows explorer. So what I did was:

1. used live cd to format drive
2. used live cd to create 2 partitions (ext4?- for linux & ntfs for windows)
3. Installed windows
4. wanted to install linux via wubi but was unable to access from wubi installer, drive would not show up in install paths.
5. used windows disk manager to make partition visible to windows, which changed it to ntfs
6. from that point I was able to install linux on the partition and dual boot.

However I have had some boot issues, windows boots fine 100%, but linux has been hit and miss, but if I retried or chose the recovery option it would boot ok for awhile then it would act up again. I'm starting to think I might have screwed this up from the get-go. Thanks for all the help, if you think this is fixable, let me know, and I'll keep trying what ever you guys come up with. However if you think a fresh install with some changes to the partition is my best bet, I'm willing to do that also. Thanks again.

just to reiterate, I can not boot into linux at all now, above paragraph makes it sound like I can. Don't want to confuse anyone. thanks.

p.s. I need to head to town for a few hours but will be back later to check replies-suggestions.

ubuntu@ubuntu:~$ sudo fsck /media/win/ubuntu/disks/root.dsk

Try root.disk

[Ubuntered]

Try root.disk

Doh! : \, dam, I actually double checked to make sure it was correct, and still missed it. Oh well, on the up side, I'm making progress.

Here's what I got:

After this, I exited terminal, shutdown and rebooted to hard drive, selected my Ubuntu partition and bingity bango, hot dam, it booted perfectly, first try. I'm very impressed with this forum, and would like to offer a special thanks to user "bcbc" who's quick responses and good advice, fixed this problem for me. . With strong solid support like this, Linux is getting harder and harder to beat.

You're welcome! Glad to hear it worked out.
