In case you need some support: Dual Boot Installation with Windows 7 and XP

Option Two is for you, 7 & XP dual boot installation when Windows 7 is already installed.

windows 7 professional 64 bit & Virtual PC XP mode

Kari: I have been studying the tutorial you mentioned. I have been experimenting with different computers and configurations. I have an old laptop: ACER, T2060 Processor @ 1.60 GHz, 1.0 GB memory, 32 bit Windows 7 Home Premium. ProE CAD runs fine , slow but a little faster than my old 800MHz and 512 MB memorywith Win XP. My new computer that I am trying to make work is: Dell XPS-8500, Intel Core i7-3770 @ 3.40GHz, 12 GB memory, 64 bit Windows 7 Professional. Is the problem 32 bit versus 64 bit? Do I need to install 32 bit Win XP as my dual boot? Is this possible?

There's absolutely no problems to have a 64-bit Windows 7 and a 32-bit Windows XP dual booting on a PC with 64-bit architecture.

A 32-bit Windows OS can only use 4 GB of RAM, so just remember that if you install a 32-bit Windows on that new computer, be it 7 or XP, it can not use "the last 8GB" (you mentioned it has 12 GB).

Like many other old school geeks I find dual boot easier to set up by starting from older OS i.e. install XP first, create partitions for Seven and then install Seven.

I ask some of our resident installation / dual boot geeks to take a look of this thread to get some fresh ideas for you.


EDIT: I noticed the tutorial link in my previous post did not work. It is fixed now.

windows 7 professional 64 bit & Virtual PC XP mode

Kari: You will not believe what I just did. I installed a copy of Win 7 home premium 32 bit in my new partition and my CAD program works fine, way better than in virtual PC. I can load my whole house model and now it repaints in less than a second. The graphics drivers need to be loaded in the new partition and printers and such yet. However the bcdedit would not open for me, I have not searched for an answer yet. When the computer starts I have two boot options, Windows 7 and Windows 7. I know the first is Home and the second is Pro but I would like to change the names so that it is more descriptive

Linux CENTOS 7 / various Windows OS'es and servers

Hi there

performance of a VM depends on many things but usually the amount of RAM available is generally the most important factor followed by the quality of disc drives -- for example if you are running a vm stored on a USB2 disc it could take a long time to start up.

Windows XP mode itself is a HORRIBLE solution -- performance is a DOG and graphics are a disaster zone.

Download VMware vmplayer --latest version is really good (and FREE) and with a decent computer your XP virtual machine can run at almost true native speed. The graphics have been fixed too so DVD playing on your VM is possible and a lot more "legacy" games playable too.

The only drawback to using VMware is you'll have to install an XP system as your virtual machine --but the effort is definitely worth while.

I'm currently running a Virtual 2003 server using VMware's latest software and the performance of my applications running on it are fine.

I've attached an old HP plotter on it --works brilliantly -- this hardware is of course no longer available --modern stuff would cost around 20,000 USD so I'm not getting rid of it any time soon. Even on the W2003 server I'm using the Windows 2000 driver for it (that was its last update !!).

(Another advantage of using latest version of VMware is that VM's can run in the background --and remote users can log on to applications without even having to have an account on the HOST --very useful for my windows 2003 virtual server.

Unity mode is also fully enabled too if you like that feature in XP mode.

I really say again for using a VM forget XP mode - it's HORRIBLE. It was a quick cludge made by Ms in a hope to get people to move away from XP quickly.

(Thank goodness Ms haven't done the same trick with Windows 8 running in "W7 Mode" !! although reading lot's of posts on the W9 forum perhaps Ms should have done this too !!).

I see you've fixed your immediate problem - but dual booting is usually inconvenient and best avoided if possible -- run a Vm with the latest version of VMware player -- then you only need to start the vm when you need it and it will run at almost Native speed !!!!!. VMware have done an EXCELLENT job on the latest versions --VMware workstation 9 (Paid) and VMware player (Free).
