Wubi grub error

[Newbie]

I have installed Kubuntu 9.10 through Wubi. After the last update I get this message when trying to boot into Kubuntu:

GNU GRUB version 1.97~beta4

Minimal bash-like editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists possible device/file completions.

sh:grub>

If I use the command ls, I get this message:
(loop0) (hd0) (hd0,6) (hd0,5) (hd0,4) (hd0,2) (hd0,1)

and with the command ls /boot, I get:

2.6.31-17-generic-pae

I have tried to use this command at the grub prompt:

set root=(loop0)
linux /boot/vmlinuz-2.6.31-17-generic-pae root=/dev/sda1 loop=/ubuntu/disks/root.disk ro
initrd /boot/initrd.img-2.6.31-17-generic-pau
boot

I starts ok, but when I use the command boot, it stops after a little while and writes a lot. I have noticed these sentences:

unable to mount root fs on unknown-block (8,5)

2.6.31-17-generic-pau swapper not tainted #54 Ubuntu

I tried changing sda1 to sda2, sda3, sda4 etc. without luck so far ....

I really hope someone can help me solve this problem so I can start using Kubuntu again

Re: Wubi grub error

Sorry, don't know anything about Wubi. Do know that Wubi-GRUB has had some bugs, make sure you are not hitting that wall.

Re: Wubi grub error

If you haven't already you might want to familiarize yourself with the Wubi forum and guide. I lot of useful information there. I have never used Wubi, but many people have. So help should be forth coming.

Re: Wubi grub error

I tried everything to correct this following many forum suggestions and could not get it to work. I learned that there is a known bug that prevents Wubi/Grub installing correctly.

Sorry to say, but I ended up installing 9.04 and hope it will be fixed when 10.04 is released.

You could try the suggestions on this bug report to fix it...

this is a well documented bug.

follow the instructions in post #210.

Not many people use Wubi here. They are not familiar with this bug.

Re: Wubi grub error

Thanks for all your replies...... seems like I should just forget about the Wubi install. Does anybody if there is a way to access the files and some KNotes I made on Kubuntu / Wubi?

um, the fix I pointed to didn't work?

What happened when you tried it?

if not, try post #149, that also worked for this error, for me.

Re: Wubi grub error

to acsess your files in the wubi install you can try this from a live cd

Boot the Ubuntu Desktop CD, or another LiveCD, then mount the windows partition:

sudo mkdir /win
sudo mount /dev/sda1 /win

Replace sda1 with the appropriate device (a = disk, 1 = partition number), then mount the virtual disk therein

sudo mkdir /vdisk
sudo mount -o loop /win/ubuntu/disks/root.disk /vdisk

Now the content of the virtual disk will be visible under /vdisk. 7.04 users will have to install ntfs-3g first and specify it as fstype to gain r/w access.

To check the filesystem you can use:

sudo fsck /win/ubuntu/disks/root.disk

hears the guide I got this from

https://wiki.ubuntu.com/WubiGuide#Wh...%20bootloader?
