(by "change" I mean get rid of Win and permanently change to Ubuntu) while keeping all the data in my computer (Videos, Pictures and some movies) intact and accessible while using Ubuntu.
I would advice against this. If you want to keep your data and keep using a Windows formatted partition you will at some point need to fall back to Windows for maintenance of those partitions.
If you want to keep this data make a backup and format d:, e: etc into ext4
so it is native Linux and restore that backup to the Linux versions of these folders.
Otherwise I would suggest you shrink the windows partition, create an unallocated partition and install Ubuntu into that. You will then have a system with 2 operating system (or a dual boot) and Ubuntu will happily let you use the Windows partitions to store and retrieve data from. That can be used to clear out your Windows partitions by moving your data to Ubuntu and then reformating those partition to a Linux version (ext4
).
Like wordpad, excel, word, spreadsheet, database etc., you know for projects and stuff)
If you want to keep hanging onto Windows: go dual boot. WINE is not worth your time.
Wordpad you do not need in itself as it is just a text editor. We got plenty that do a better job. Excel(=spreadsheet) and Word can be done with LibreOffice Calc and LibreOffice Writer. It is sort of the same but also a bit different (and some of the basic things are done differently so it can be annoying if you are used to Word). But the learning curve is not that difficult. Database: MySQL is the leading database and available. If you are familiar with Access the learning curve is not too difficult.
Again: I would advice to go dual boot. Get the hang of Ubuntu, get used to the software in Ubuntu, move your files over to Ubuntu, shrink Windows as much as possible and if you ever reach a moment where you can say "hey I do not need Windows anymore" remove it either from grub or actually from your system.
Prepare for a disappointment but do your best to get the hang of Ubuntu. If you can not switch for whatever reason you can easily revert to Windows.
As an alternative you can also install Windows INSIDE Ubuntu using virtualization (with VMWare or VirtualBox). Works best with solid machine with lots of RAM though.
