My netbook dual-boots between Win7 and Ubuntu. Been that way for a couple of years, works fine.
But I have a lot of Windows stuff, a lot of time and effort invested in it, and Ubuntu only rarely gets used. So I want the space back.
I think I can probably use Paragon's Hard Disk Manager suite to remove the partitions and redistribute the space (I have a primary and an extended partition. The extended partition contains all the linux-relevant partitions and an NTFS partition that I set up to be shared between the two OSes. So undoing all that it going to be fun and I'll probably do it a bit at a time, for safety.)
However, Grub has moved into the MBR and I can't work out how I'm going to make it go away.
The general answer courtesy of Google is to boot from the Win7 installation disk, start the recovery console and use fixboot.
I can't do that. I don't have a Win7 installation disk or a DVD drive.
I can't even work out how to install the recovery console. I'm obviously being stupid today.
