From: Jason Filippou on 21 Jun 2010 18:20 Hello list, I have had a laptop wearing Linux solely over the last few years and today I decided I'd install a Windows partition on it, with aim to dual boot. After preparing an NTFS partition by using the gparted live CD, I installed Windows 7 on the newly created partition. Thus, so far I have the primary partitions /dev/sda1, an ext3 partition holding my Squeeze installation, and /dev/sda2, holding my Windows installation. There's also the /dev/sda3 "extended" partition and the /dev/sda5 "swap" partition. Here's a gparted screenshot taken from within my debian installation to prove my claims: http://img199.imageshack.us/img199/1819/mypartitions.jpg When the installation was finished, I would only boot into Windows 7. Somewhat accustomed to this loss of the Grub boot loader, I booted from my Squeeze installation CD, entered Rescue Mode and reinstalled GRUB in the MBR of my only hard drive (that corresponds to the /dev/sda1 partition). However, even though I reclaimed Grub, Grub would not detect my Windows partition on bootup, and give me the options of boot into debian. I tried reinstalling GRUB on other partitions, but Windows was (and still is) unbootable on startup. I had a look at my grub.cfg and didn't see a "menuentry" corresponding to the windows partition, even after running update-grub. What are the steps that I need to follow in order to dual boot my system? The only OS I have currently access to through Grub is Debian (with the option of two kernels, but that's not really relevant).

Make sure it is installed and rerun update-grub. If it still won't detect your Windows you can try also writing a custom entry in the file /etc/grub.d/40_custom, but I bet the os-prober maintainer would want to know about it.
