Ubuntu Installation :: GRUB Looks Like Not Finding 9.10?

I bought new Sony VAIO NS31S. It had preinstalled Windows Vista. I wanted to go back to Ubuntu, cause I used it (but never been really understanding how its working) on my previous notebook. I downloaded Wubi with Ubuntu 9.10, installed, rebooted - everything was fine. I even had connection to the web (what I was very suprised to see, cause I had troubles with that Net provider on my old hardware with U 8.something).

I removed several programs, mainly games or accessories for PalmOS, etc. On the second hand I installed Kadu, Google Chrome (here I couldnt use Software Center, it was installed form downloaded package), Netbeans, and then some errors occured, so I allowed system to get updates. After installing them I switched off computer, and today (the whole story was yesterday and day before) I wanted to boot Ubuntu, but GRUB gives me command line & some info(in a while I swith VAIO off, go to the old machine, and try to rewrite text from GRUB here). I TABbed, and there was a list of commands, so I tried some of them, and It looks like my system is gone. On Windows side I think its all ok - here's my folder hierarchy:

Code:

/ubuntu
//disks
root.disk
swap.disk

[code]....

if there are /'s before files name it means its a directory. else its a normal file. Whitespaces shows what belongs where.if there already has been topic like this. Ive searched this forum for 'wubi' 'vaio' and 'grub' and there was nothing I thought might be simillar. Is it possible to switch off double system choosing? I mean Windows gives me choice to boot Windows or Ubuntu, or use some windows recovery tools. If I try to boot Ubuntu, there comes GRUB, which gives second choice of choosing Windows. But this is smaller problem, then nnot booting linux I rebooted once again. Here's what GRUB says:

Code:

GNU GRUB version 1.97~beta4

[ Minimal BASH-like line editing is supported. For the first word, TAB lists possible command comletions. Anywhere else TAB lists possible device/file completions. ] So I pressed TAB, found some commands (there's quite lot of them, so as for now I wont write them here).

Code:

sh:grub> ls
(loop0) (hd0) (hd0,2) (hd0,1)

Code:

sh:grub> linux
error: no kernel specified

Code:

sh:grub> boot
error: no loaded kernel
