Grub Boot Screen cannot open Windows

[xueyi...@gmail.com]

I made an entry for Windows 7 on the Grub Boot Screen, but when I attempt to open it, it shows the error "hd1 cannot get c/h/s values".

I've tried changing BIOS to UEFI mode, but it displays the same error. I've also tried changing the device boot order.

I've also tried to recover Windows through sudo mount /dev/sdC on both BIOS and UEFI mode, but the terminal states that the device does not exist.

I know that Qubes is working fine, and that I did not overwrite the Windows OS file (it still appears when I check the file system on Qubes).

I wish to be able to dual boot Windows 7 with Qubes 3.2 without losing any programs installed on Windows 7 and without messing up Qubes. What do I do?

Run os-prober and it should automatically create appropriate GRUB entries.

The terminal replies with "os-prober: not a shell built in".

Looks like you'll need to enable os-prober in grub first.

Is there any specific command to enter for that?

Easiest way is to manually edit the grub configuration files and just pass through from grub to windows.

There are many ways to do it depending on how your system is built and set up.

Google it, and there will be many ways to do it, or else you can inform us here for your setup, and the grub config is easy to do.

HDD Layout (Wether HDA HDB SDA SDB etc... And what the partition layout is completely. an 'fdisk -l' run as root will suffice.)

Then I can easily tell you what you need to add in where to do it.
