Grub does not show Win7 [Somewhat solved]

[Teunis]

I hardly ever use Win7 but yesterday I noticed it's no longer offered as a boot option on this fully up to date HP TouchSmart.
Last time I used it is some weeks ago so the option probably disappeared during the last kernel upgrade.

Running os-prober does show Windows 7 as installed but update-grub does not add it to the options or even recognise it.

Any suggestions where to look?

I think something broke there. :P

I would first reinstall the grub-pc package, then boot a Live CD, mount the Kubuntu OS partition, and reinstall grub to the MBR of the applicable hard drive, using the "root-directory=/mnt/kubuntu" option to put everything needed in /boot/grub.

If you really need to get to windows you could try SuperGrubDisk
And you can manually edit an entry to grub for windows too

I've gone the way of an entry in /etc/grub.d/40_custom and it works. 8)
Still a weird error...

menuentry "Windows 7 (loader) (on /dev/sda1)" {
insmod ntfs
set root=(hd0,1)
chainloader +1
}
