Grub lists Windows partitions but will not boot into Windows

[bard]

Fresh install of Linux Mint 13 today, with the intention of dual booting with Windows 7. Installation went fine, but I can only boot into Linux Mint, not Windows 7. Grub lists two Windows 7 menu options, but selecting either of them causes an "unknown file system" error and dumps me into a Grub recovery prompt. There, I have to manually reset the root and prefix options, as they reset hd0,msdos6 when they should be hd0,msdos5.

I have found a few similar troubleshooting guides so far, but so far no amount of updating/configuring Grub has been successful.

I ran Boot Repair twice, once to fix grub errors, once to rebuild the MBR, but it didn't fix anything. Here is the log:

fdisk output:

Thanks in advance!

Some reason grub is installed to windows partition also, so you can repair windows boot using windows´s installation DVD or repair CD by running command Bootrec.exe /FixBoot

You can download 7´s recovery CD from here:
