All discs come up as executable bits and will not run; how do I get ubuntu off if cds will not run?

There is no single best so no it's not, nor is Windows and nor is Mac.

If you use:

wine /path/to/filename.exe

It should fly. You can also use playonlinux which may help

you can install wine by going into System>Administration>Synaptic Package Manager

type wine in the search box and select it, then click the big green arrow to install.
winetricks might be there as well (i don't use wine tricks)

when installed, click configure wine and press enter to accept the default, unless your games run only on a specific version of windoze, then you'll have to set up wine.

right click on your game then click open with wine.

I am using Wine and when it starts it still says the executable bit.

Ok now the executable bit is gone but the computer cannot find its autorun software

Ok ok wait a second I used Wine q4 and am finally getting some results but Assasins creed still does not want to let me install lets see what I can do; i'll try again.

Ok I have been working on this for another hour now and finally installed assasin's creed but now Wine cannot locate the disc when I press play...

Is the game in the wine appdb and known to work?

I just researched that and found that there may be many bugs when playing so how do I uninstall ubuntu completely, because I love gaming?

Just reinstall windows and delete the Linux partitions

Ok sweet so all I have to do is put in the windows 7 disc and windows will start running and I can install it; I wont have to start windows through wine?

Yes. You will see the partitions but just delete them (this will destroy the data) and partition as you wish for Windows. Your only OS will then be Windows

THank YOu actionparsnip have a Merry Christmas and a happy New Year! :)

So I finally got a Windows Vista CD how do I reformat my partition hardrive to NTFS?

as actionparsnip would say, we only support ubuntu here. if you need help with windoze, you should try a windoze forum.

anyhoo. you don't need to format to ntfs. the installation does it automatically.

wow thanks and I know you may not care but because you guys are so helpful I am definietely going to dual run ubuntu with windows Thank you so much ~!!!! The community truly is amazing :)
