I have computer laptop dell inspiron r15 without any OS n5110 preinstalled

I bought a windows 7 ultimate retail how can I do a windows OEM 7 dvd to my laptop using the key to selling to retail?

The product key will determine which path he comes (selling retail or OEM). So if the COA sticker attached to your Dell laptop (look at the bottom or in the battery compartment) is for Ultimate, then using that key with the copy of Windows 7 Ultimate you purchased installs it as an OEM license.

If you have purchased a license for Windows 7 Ultimate retail and use the key provided with you won't be not able to convert it from the OEM license is already at retail.

If my suggestion, just install your license as is.
