Smart BootManager is an os independent BootManager which has easy to use interface and many other features. The main goals of SBM are to be absolutely OS independent, flexible and full-featured. It has all of the features needed to boot a variety of OS.
Smart Boot Manager erased my existing boot sector and made my machine un-boot-able. Make sure you have recovery disks made and recovery console installed before you experiment with this one. I wish I did because it wiped out my XP partition without even letting me know it was going to change the boot sector. Best not to try this on any machine you can't sacrifice!
It ruined my partition table without warning me. After an innocent choice of the "Boot it" command, it asked me to confirm saving modifications, and that was it. The menu is obscure. It show unreversible operations, such as marking a partition active. It made a mess, but we can understand that software sometimes can't handle well a given device or a recent filesystem type. What I can't understand is that it does not warn you that it's just about to make a mess.
This deleted the NTFS table for my drive!!!!!!! Fortunately I had a Linux install disk, ran testdisk, and restored my partitions. BAD! Very BAD!
