How to un-do a dual boot W7/WXP PC

When I bought Windows 7 a few years ago I wasn't confident in it so I set-up this PC with a 2nd partition, put W7HPx64 on it, leaving the first partition with Windows XP x64 Pro, using EasyBCD of course. Lately since I've not used XP64, I want to use Acronis True Image to restore the W7 partition to a SSD, and that's it: one drive, an SSD, no WXP at all.

How to go about doing this? Just restore the W7 partition to the SSD and repair the boot blocks? How exactly to do this?

I'm sorry; this is probably an old question but I could not find any threads on it nor anything in the wiki.
