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.

Can you edit your question and explain exactly what isn't working? You state you can boot both OSs, so what is the problem? How does the title fit into the issue? – Paul Jul 23 '12 at 4:08
Pault: I can boot booth OS but I need grub2 to boot Windows? What if I doesn't want Linux anymore? What if my Linux get corrupted? I've tried to boot from my Windows to no avail? Btw. After an update of Linux this happens exactly to me. – Betterdev Jul 23 '12 at 7:52
Are you saying that you are testing Windows Recovery just in case something goes wrong? – Paul Jul 23 '12 at 13:18
Paul: I don't understand? I got problem to boot at all my OS. Now I'm wondering why I can't boot with Windows Recovery my PC and only with chainloader? Do this sound weird? – Betterdev Jul 23 '12 at 13:40
It is just unclear. You have said that you can boot both OSs successfully, and you have said you have a problem booting all of your OSs. These cannot both be correct. – Paul Jul 23 '12 at 23:25
