In reality, the windows bootloader on the MBR is not even a bootloader. It's only a small piece of code that continues the boot process where the boot flag is. That's why it's easy to reproduce it even with linux tools.
The thing is that grub2 is not designed to work on a partition, and that's where you have to install it if you don't install it on the MBR. If vista doesn't even work, I think you are giving too much thought to the windows bootloader. Simply use grub2 and you can restore the windows bootloader when you want to.
If you do install ubuntu/lubuntu, note that you can't simply delete the ubuntu partition in future. It's better to restore the windows bootloader first, test that vista is booting, and only then delete the linux partitions on your disk.
But all of that is not very important or urgent, we are talking about IF and WHEN you want to remove ubuntu.
More important is the fact that your hdd doesn't have unallocated space on it. Almost all hdd belongs to the vista partition. You need to shrink it so that unallocated space is created.
But shrinking vista is best to be done by windows Disk Management. If you can't boot vista, you can't do that.
How did you plan to create the unallocated space for ubuntu?
If vista is not working, personally I would back up all personal data from it, and reinstall it on a smaller partition, so that it leaves space for ubuntu on the end of the disk. That will have two benefits:
1. Ubuntu will have space to install without shrinking any partition.
2. You will also get a working vista installation.
In this situation it's pointless to keep vista and on top of that you are getting so worried about it and its bootloader.
