    Default missing operating system! can't go back to windows 7!

    hello everyone,

    I cannot access my windows 7 anymore, I was trying to make a bootable USB drive, i uploaded BT4 to the usb, and followed the directions on offensive security, (http://www.offensive-security.com/vi...b-install.html) I got up to installing GRUB, but never completed it, i think i made an error somewhere Im not sure.

    i might have partitioned it incorrectly? did i accidently format my w7?

    here is my sudo fdisk -l


    Disk /dev/sda: 120.0 GB, 120034123776 bytes
    240 heads, 63 sectors/track, 15505 cylinders
    Units = cylinders of 15120 * 512 = 7741440 bytes
    Disk identifier: 0xb2c45f44

    Device Boot Start End Blocks Id System
    /dev/sda1 * 1 272 2056288+ b W95 FAT32
    /dev/sda2 273 15505 115161480 83 Linux

    Disk /dev/sdb: 4110 MB, 4110417920 bytes
    127 heads, 62 sectors/track, 1019 cylinders
    Units = cylinders of 7874 * 512 = 4031488 bytes
    Disk identifier: 0x0009e87d

    This doesn't look like a partition table
    Probably you selected the wrong device.

    Device Boot Start End Blocks Id System
    /dev/sdb1 ? 409369 440697 123339962 f4 SpeedStor
    Partition 1 has different physical/logical beginnings (non-Linux?):

    phys=(870, 235, 61) logical=(440696, 102, 48)
    Partition 1 does not end on cylinder boundary.

    Partition 3 has different physical/logical beginnings (non-Linux?):

    Partition 3 has different physical/logical endings:
    phys=(370, 32, 37) logical=(28651, 88, 22)
    Partition 3 does not end on cylinder boundary.

    Partition table entries are not in disk order


    I'm not too sure as to what i did wrong, anyone have any pointers? Thanks.

    I've also tried the windows 7 recovery disc, but it doesnt display the OS.

    did i FUBAR?
