I remember some time ago installing Vista on a new partition of a "Ubuntu / Vista" machine, and the Ubuntu boot menu was gone?

So now there is a machine with Vista and a few Ubuntu installations (Ubuntu 8 and 9.04), and then another boot selection made by Wubi.

So there are 2 boot selection menus, one after the other. The first one with a few choices, and the second one with 2 choices.

So now if Windows 7 is installed on this machine, will it wipe out one or both of the boot selection menus? In that case, will making a partition bootable again involve some work?

If that's the case, I may as well boot to all the partitions first and make sure I copy the data over and delete the partitions I don't need, and keep the needed OS to a minimum and then install Windows 7, so there will be less work to make the partitions bootable again.

Yes, it will cause problems. Use EasyBCD to fix it after, it works really well and it's free.

You should be able to simply boot off the Ubuntu DVD and reinstall Grub in the MBR without difficulty. In my very limited test, Windows 7 did eliminate Grub as part of its install process.
