Install Windows from Partition with Grub

[Intrepid Ibex]

So how can I (e.g. after using dd) boot to this dd'd Windows Installation partition with Grub?

I just want to do this as installing Windows from Hard Drive is much faster.

- Thanks from all the help already

E: The solution was Unetbootin. Did nothing special myself (defined the .iso path and the partition (/dev/sda4)), the app did all the work.

Well, okay, either I'm gonna do this with grub(2) with:

menuentry "For when hell freezes over..." {
	set root='(hd0,4)'
	chainloader +1 # I dun have the Windows's MBR override here so maybe chainloading won't work
}

or with Unetbootin.

Try "sudo update-grub" from a terminal. Also set the boot flag on that partition assuming this to be the only win install.

Uhhh... I never had a problem with updating (/boot/grub/)grub.cfg.. Also thanks but I already have set the boot flag. The problem is to just adjust the correct parameters (chainload or not), the filesystem (dd or ntfs) and stuff like that.

Okay, weee, Unetbootin was the solution. I just added the Win 7.iso, defined the partition where I wanted it to (/dev/sda4) (USB Drive -> Show All Drives (Use with care) -> /dev/sda4) and (of course) just pressed *OK*.

This (I don't know how but somehow) created a working MBR setup to boot from the partition I put the setup into (/dev/sda4).

What really took me by surprise was that about 2 years ago ago I had no luck with Unetbootin what so ever (with either Ubuntu or Windows).
