I re-installed ubuntu with a new partition

oot@glavkos-laptop:~# fdisk -l

Disk /dev/sda: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot Start End Blocks Id System
/dev/sda1 * 1 1020 8192000 c W95 FAT32 (LBA)
Partition 1 does not end on cylinder boundary.
/dev/sda2 1020 6797 46403320+ 7 HPFS/NTFS
/dev/sda3 6798 19458 101692091 f W95 Ext'd (LBA)
Partition 3 does not end on cylinder boundary.

/dev/sda7 11861 12082 1783183+ 82 Linux swap / Solaris

This time Grub works fine ...but i can not still load my Vista.
I try to load Vista from the sda2 partition ...If i try sda1 (i think the recovery mode), will that affect Grub again?

You can use an Ubuntu installation disc or USB drive to do this. Boot into the USB drive and use the the Linux system to repair GRUB. ... After repairing the GRUB boot loader, you should be able to restart your computer again. The GRUB2 boot loader will appear and boot Ubuntu normally.

If you do see the GRUB boot menu, you can use the options in GRUB to help repair your system. Select the “Advanced options for Ubuntu” menu option by pressing your arrow keys and then press Enter. Use the arrow keys to select the “Ubuntu … (recovery mode)” option in the submenu and press Enter.
