No, it should be bootable. I don't ever install an OS without first wiping the previous on off, including partitions.
In order to install the upgrade version of Windows 7, you must have a qualifying Windows operating system installed and activated
. You cannot install an upgrade version of Windows 7 on a blank hard drive. The installation procedure does not ask you to insert a Windows disc in the drive for verification, the actual qualifying operating system must be installed.
If you do not have a qualifying Windows operating system installed with a genuine license activated, then you cannot use the upgrade version of Windows 7 - you would need a "full version" Windows 7 license.
1. A qualifying Windows operating system must be installed.
2. The qualifying Windows operating system must have a genuine license (product key) and it must be activated.
3. To upgrade, boot to the qualifying Windows desktop, insert the Windows 7 Upgrade disc in the DVD drive.
4. When the setup menu appears, select Custom (advanced)
to initiate a clean install procedure.
