When I updated my dual boot (Windows and Linux) PC my grub menu.lst file was deleted and I could no longer boot into Windows or Linux.
Finally I have succeeded in installing grub2 and I can boot both OSs but I cannot repair my Windows OS with the recovery console.
I've still some problems with grub2 and Windows 7 but I expected to repair it from the recovery console.
I assume the mbr of my Windows disk is ok because it works with the chainloader from grub2.
The problem is I cannot boot Windows without the chainloader or grub. It even failed to write a new boot sector because Windows cannot detect the filesystem. This happens to me with the bootrec.exe /FixBoot command. I also cannot command bootrec.exe /RepairBCD it gives the same error.
