I have a Dell Studio 1555 laptop that came preloaded with windows vista 32 bit. I am curious if its possible to install Windows 7 64 bit OS on this machine?
welcome to the community
Would like to inform that the system has the required hardware configuration that supports win 7 however, we do not have compatible drivers on the support website. You can try installing the driver for vista 32 bit which may work.
please let me know for further help
Thanks & Regards
I think all of these models are compatible with Windows 7 64 bit but to be sure run the Windows 7 Upgrade Advisor.
With regards to drivers, although Dell do not have a driver set listed on their drivers and downloads page. Their range of drivers is vastly superior on their ftp website you will see they have practically a full driver set listed for WIndows 7 32 bit and Windows 7 64 bit. I have provided an unofficial set which have got several users going without problems (mostly from the ftp website). You should install in order.
