Use largest continuous free space?

[nexgen]

Im about to install ubuntu and want to make sure if i used the guided option "Use largest continuous free space" that it wont affect my Windows Vista install at all because i used partitioner to delete a opensuse install i had and now i have 80GB unallocated free space and about 300gb for the Windows OS, so will that option use the 80GB unallocated space and leave windows alone?

Yes.

FYI: I NEVER leave computers to chance. Backup first. Always be prepared. It should word as planned. It did work that way for me. Then again I had backed up my system, so no worries.
