Q: Questions regarding Windows 7 Home Premium upgrade license

Networking on Win 7 Home Premium

I am looking to purchase Win 7 Home Premium with an upgrade license. 

First I wanted to know, if like previous versions, whether I have to retain prior version CD's in order to confirm my upgrade during installation? This install will be on a clean formatted partition and not over one of the XP's that I have installed. 

Second, when viewing the comparison of versions, I noticed that the next higher version noted easier for business networking connections. I just wanted to insure that it wouldn't be difficult to connect my 2 PC's at home currently connected wirelessly through a Linksys Router.

Third, I will be installing Win 7 on the master drive along with a working version of XP that I need to retain, while I am testing the new Win7 OS and making sure I will eventually be able to use it as the working OS. I will then use the XP as a backup. Having Ubuntu on a slave (2nd) drive, I understand that installing Win7 will redo the MBR to just this XP and the New Win7 and remove my Ubuntu bootup. Do you see any problem in running the Ubuntu GRUB LiveCD, resetting the MBR to boot Unbuntu which then links to the Windows Boot Manager where I can then select either XP or the new Win7?

1) Yes you need your COA and proof of purchase in order to use an upgrade version of Windows. Once you upgrade you can not use the Windows XP product key you upgraded from to create a Dual Boot system.

2) The wireless connection is not a problem for Home Premium. If there is going to be a connection issue it would most likely be because your wireless adaptor is not supported in Windows 7 although most are. The physical router should work with any wireless adaptor you buy as long as it support 811G or N if possible.

3) Perferred  Installation sequence should XP first, Windows 7 second and then Ubuntu.


Use EasyBCD to manager your boot menu.

These steps assume that you have Windows already installed and are installing Ubuntu to some free space on the drive. If that's not the case, you'll have to follow the steps a little more loosely than they're written.

The requirements for upgrade media though is that you have a previously qualifying operating system such as Windows XP or Vista installed to use it. From the Windows 7 End User License Agreement.

15. UPGRADES. To use upgrade software, you must first be licensed for the software that is eligible for the upgrade. Upon upgrade, this agreement takes the place of the agreement for the software you upgraded from. After you upgrade, you may no longer use the software you upgraded from.

So, if you are still denied, you will have to simply reinstall Windows XP or Vista and let it do the eligibility check.


Windows 7 Home Premium supports standard workgroup networking, you can network up to 5 systems and access resources concurrently, if you need to network more machines, Windows 7 Professional which supports up to 10 machines would be recommended. Windows 7 Home Premium also supports HomeGroups and also creates them, this feature is exclusive to Windows 7 only. Standard networking allows you to network either either Windows XP, Vista, Windows 7 or even Linux and Mac OS X.

Windows 7 Home Premium will do just fine for your needs wither wired or wireless.

If you need to join a Domain at your place of work, you will need Professional or Ultimate.


When installing Ubuntu with Windows, you should install it after Windows. If you install Windows 7 after Ubuntu it will remove GRUB and use its own MBR. For information about dual booting Linux and Windows, please see the following article:
