I intend to use the same Windows 7 x64 installation both through BootCamp and Parallels. I understand that is possible. (??) I have already installed Windows 7 using BootCamp.

Symptoms Windows Virtual Machine installed from Boot Camp partition shows that it is not genuine and ask for activation. Cause Windows. Windows; Parallels. May 22, 2011. I partitioned my HD and ran Windows 7 on Bootcamp. Activating Windows7 in Mac Parallels. Windows 7 Activation In Parallels.

I've not activated it yet - should I install parallels and activate it through there or when I've booted into it through BootCamp? The hardware would appear different to Windows I presume.

I don't want to find myself in the situation where I'm asked to reactivate every time I switch. A few quick questions: - Does BootCamp degrade performance by a lot? (My OCZ Vertex 3 rated at 550/520 MB/s is returning just 290/280 MB/s in Windows under BootCamp - and a WEI score of only 7.1 [27 sec unoptimized boot] - my Intel X-25M G2 scores a 7.7 on a 2.5 year old HP dv5t [12 sec optimized boot]) - Is there anything similar to CrystalDisk for Mac?

Sorry for the bump but I didn't want to start a new thread with this one going unanswered. I'm in the same boat as the OP. I have Windows 7 Ultimate x64 installed in Boot Camp and Mac OS 10.6.7 on the other partition. I have Parallels Desktop v6.12090 installed (latest version). I have Windows activated in Boot Camp but it won't activate through Parallels.

My Parallels hardware environment gives Windows all 4 cores and 4 GB of RAM. This Mac has 4 cores and 8 GB of RAM available. Is it possible to activate in both environments?

Parallels has a support document out provides instructions so you can supposedly activate in both environments but it doesn't work. Nope, BootCamp won't degrade performance cause it's not emulating Want to bet?

Except for graphics, Windows runs much faster in the new Parallels than BootCamp. This is both reflected in benchmarking and Windows' own WEI scores. I have an OCZ Vertex 3 SSD installed in my 2011 Macbook Pro, and it actually takes 19-25 seconds to boot in BootCamp. It takes only 14 in parallels. The WEI score for the SSD (which would be 7.9 on normal Windows laptops) is only 7.0 in BootCamp. It jumps to 7.7 when I test it in Parallels.

The speed differences are also seen when I test using CrystalDiskMark - 289 Mbps in BootCamp, ~400 Mbps in Parallels. IOPS values are somewhat disappointing.

I presume the only way I will be able to unlock the full potential of my hardware would be to install Windows exclusively on the laptop without BootCamp and Mac OS X. Building Operating And Maintenance Manuals. But I need OS X to install EFI updates, for the extended battery life offered by GPU switching. Download Little Shop City Lights V3 0 0 32-te on this page.

Bootcamp is nothing more than a program which allows you to create a NTFS/FAT partition and allow a disc to run, and then inside of Windows, it is essentially a driver set.

I personally only use parts of the bootcamp drivers and then go to the manufacturers website for my products. My WEI score is considerably higher this way (although I honestly do not use Windows on my Mac anymore).

I am the original poster. I eventually used two Windows keys to activate - one for each 'hardware configuration'.

There might be a better way but it was the easy way out since I get free licenses from Microsoft. Except for graphics, Windows runs much faster in the new Parallels than BootCamp. This is both reflected in benchmarking and Windows' own WEI scores.
