When installed in dual-boot configuration, Windows Vista provides good performance and exceptionally realistic set of features. Such configuration allows you to boot from either of the operating system. When you try to install Windows Vista on a system using any other Windows operarting system, it asks you to select the target partition as 'Where do you want to install Windows?'. After you select the partiton and click 'Next' to proceed further, you might fail to do so with an error on screen. To solve such errors, you might be compelled to remove all the exisitng partitions and hence data from the hard disk. Thus, you will need a valid data backup to restore or use data recovery software to extarct the lost data.

“Error: uncaught exception: (failed UI_ASSERT)”

The installation fails after you receive this error message.

Such errors occur when the hard disk partition table is consisted of multiple partition entries. Parittion table is the data structure that describes all the exisiting hard drive partitions. The above error is generally encountered if the media is corrupt and its partition table contains several entries. In such conditions, all these entries point to a single byte offset location.
