Hello, windows vista as deleted from my friend's laptop in an effort to download windows 7.
She's getting "invalid O/S" and can't get past the message.She's need to get online to download windows 7. How can she do that
How was it deleted? an operating system doesn't get deleted while downloading.
Were you downloading from Microsoft?
If you were downloading a pirated copy, who knows what virus was included.
The laptop should have a restore partition to restore Vista, however this will restore it as new from the maker and all data will be LOST.
Maybe you mean you were trying to install Windows 7 upgrade rather then downloading, if that's the case, you need to tell how this was done ie; the procedure you used in detail.
Downloading and installing are 2 entirely different functions.
