Although I've never had problems, I think that Zaine too went through serious annoyances... He started to recommend BootIt NG instead -- if I remember correctly...
I've used BootIt NG (BING) for years. It's a great tool. Only shortcomings: can't do imaging in Windows and no incremental backup. But it's always been perfectly reliable, and it's also (I should say it's mainly) a multi-boot manager.
I ran into troubles when going Vista (whether that's wise is another story), however, and desperately needed a workable replacement for I'm in the habit of taking snapshots of the system partition every few steps when setting up a new system.
I did a quick research (too quick, in hindsight, for I didn't dig deep enough on the wildsecurity forum) and heard many good praise of Acronis TI. I downloaded the trial version but soon learned one of the its main functions I needed (can't remember which one, probably something related to operations from the rescue media) was only available to registered users, so I registered.
It's a mistake.
Turned out the problem I had with BING was related to Vista's new partition and disc signature rules (see http://www.multibooters.co.uk/
for detail). What BING can't do, TI can't either.
Besides, TI has other Vista related issues, as said in my original post.
After I registered an official complaint on their tactics (forcing customers to upgrade for bug fixes), they offered me to try a beta version of TI Home 10 (not offered on the website yet). The new build is better, but most of the above issues remain. I've just reported my findings back to them. We'll see how it goes.
This raises serious doubt, however, on whether they've really solved the major Vista compatibility issues with the brand new ver. 11. They claimed ver. 10 to be Vista ready; it wasn't. Now they're saying the same thing about ver. 11, but I really doubt it.
