Installing Linux. partitions???

[hu4228]

I put installing file in my pendrive. and now, writing this from the 'try out without installing'. of ubuntu. now I want to install it but it asks me...

should I unmount the partition?

Image didn't post. What partition is it asking to unmount (the hard disk itself? This makes the most sense as, as I recall, it'll auto-mount the actual disk but needs to have it unmounted to actually change partitions and format)

If that's the case, it's fine. The only devices you wouldn't want to unmount is what is housing the currently-running system (your pen drive)
