I installed Ubuntu with WUBI in Windows 7 64bit, and I had installed Mandriva 2011 with a disk. I tried to learn Linux with Ubuntu and misused mke2fs; after I reboot my computer, Windows 7 and Ubuntu has crashed.
As I have Mandriva, I boot into Mandriva and found

Partition table entries are not in disk order
I think I may used the following command
mke2fs -j -L "logical"/dev/sda2
but I had forgotten what kind of partition it was before I transfered it into ext3. perhaps ntfs
Data was not lost, and I can view my files as I could in Windows. In Mandriva, there are following disks:
117.2 GB hard disk, files in it is the same as my Windows D:, and Ubuntu was installed in it; 119.0 GB hard disk is my G:, with my personal files in it; 12.0 GB is the same with Mandriva / (with means root), 101.3 GB hard disk with nothing but lost+found; DELLUTILITY should be Dell computer utilities pre-installed in my computer; logical is the disk which I had spoiled, I can view nothing but lost+found; and OS is the C: in my Windows.
After I boot, grub lets me choose Mandriva or Windows. I chose Windows and it tells me:
FILE system type unknown, partition type 0x7
Error 13: Invalid or unsupported executable format
I doubt something wrong with windows MBR or something

I can boot into Linux, but not Ubuntu, it boot into Mandriva. I don't have a boot disk.
Help me find a way to make it work again.
