Maybe we may go back in theme ?
BIG QUESTION
i just delete everything except win (and how ? if i delete Grub i can't load anymore win)
or there is some way to detect what is connected with the working partition with ubuntu 10.10 and delete the rest ?
PhotoComix,
If I remember correctly the Vista Loader is the name used by grub for either Vista or Windows 7. If you have either version of Windows, the grub installer identifies them in this fashion.
One of the easiest ways to determine the partition holding the OS is through the use of
gparted; this utility is present on the LiveCD, but is usually removed near the end of the install process. It is available in the Ubuntu repositories. If you have multiple drives in your machine, there is a drop-down box in the upper right corner that allows you to select the physical drive for gparted to examine.

Note that the /(root) partition has the boot flag set in the right column; this is the partition this OS boots from.
You may also want to look at the file
/etc/fstab. This file is a text file-table of the partitions used by the OS, and may include a scary looking UUID number. This is a
Universally
Unique
IDentifier that very clearly and unmistakably identifies the partition to the OS - it is basically a hash generated to ID the partition. Anyhow, in fstab, following the UUID would be the mount point where the OS can access the file system, followed by options the OS uses when mounting and accessing the file system. In older versions of Grub, there was an option as to whether grub would use the older partition naming scheme such as "/sda2" or use UUIDs.
This is my current fstab on the same system I am using right now:
# /etc/fstab: static file system information.
#
# Use 'blkid -o value -s UUID' to print the universally unique identifier
# for a device; this may be used with UUID= as a more robust way to name
# devices that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc nodev,noexec,nosuid 0 0
# / was on /dev/sda1 during installation
UUID=a019a2ad-aa7e-4977-a891-1a2562e619ec / ext4 errors=remount-ro 0 1
# /home was on /dev/sda8 during installation

# swap was on /dev/sda5 during installation

I don't know if you have(had) your partitions set up this way, but most "advanced" users are recommending installing so that the Linux OS actually uses three partitions.The first partition is the one used by the OS itself: /(root). The second is the partition where all your personal stuff will be stored: /home. Third is the swap partition: linux-swap. By setting up your partitions in this fashion, if you do get a messed up upgrade or if you totally screw up a program install, you can fix it by re-installing the OS into the /(root) partition and pointing the installer to the /home partition (Note: If doing this type of OS recovery, remember to tell the installer during partition to NOT format the /home partition, this is VERY IMPORTANT! If the installer formats the /home partition, all your personal files in your home directory will be lost.) Unless the installation script has changed, you may have to manually set up your partitions, which is an installer option.
If you need more help, let me know; since I like to experiment with my system, I've broke and repaired it many times and might be able to at least point you in the right direction. My current system is LinuxMint 9 (an Ubuntu-based distro), but before that I had LinuxMint 8 and it was the longest-lasting OS I'd ever had.
