I recommend it as #1 choice and has been around for years.
One person said it took hours.
Google turns up people with trouble but they also created trouble and had it to begin with.
Make sure your hard drive is ready and has healthy partitions to begin with.
That you have more than adequate space for both operating systems.
that means more than just 30GB for Windows as well as free space for Mac - 20% free after to operate afterwards for each.
The Paragon forums are not that much help that I have seen - rather quiet but I use their other products daily.
If you must, feel free and safe - but make sure to have backups!
And in the last months there is $20 WinClone 3 that I don't know about but has expanded its features and supported.
I have never before seen no feedback on www.macupdate.com very odd.
MacIntouch and MacFixit ?
Paragon has been supporting Mac and Boot Camp for years with this, and excellent NTFS and HFS drivers to add write support.
CampTune could also be used to prepare a drive for Windows.
My one complaint has been why do they have so many products that overlap? backup, manage, partitioning, I tend to buy the Suite for home users rather than the Pro edition that are swiss knife with everything. They have tools to move windows to and from another disk drive, system, or to/from a virtual image to physical.
