Hey all. I've been a "dual-booter" about 2 years now. I am far and away a Linux guy now, but I figured I'd put a copy of Win7 on my PC since I like to game. (Much easier than messing with Wine...) At any rate, I thought I'd let the community know that I was able to get Ubuntu 10.04LTS and Win7 with Daz's loader to coexist happily on the same PC. Note that this is a real dual-boot setup and not a Wubi or Virtual Machine install. This is how I did it, and it worked, but there may be other methods that work just as well. It's very easy. What you need: A copy of Windows 7 (appropriate for your architecture) A copy of Ubuntu 10.04LTS (appropriate for your architecture) Daz's Loader (only use this loader, explained below) A computer... Directions: 1. Make sure the hard disk you are installing to is big enough for both OS's. 160gb will probably be plenty big as long as you have another partition elsewhere to install games and store personal stuff. Make sure you have a new, blank partition to install Windows 7 onto. (You can, of course, set this up during the install.) Generally you want Win7 to be on the first part of the disk to improve read/write times and because Windows is picky about where the Master Boot Record is located. I make the Win7 partition about 80gbs. 2. Download a copy of Windows 7, burn and install per this guide. Remember you will probably have to set your boot order in your BIOS to boot from CD or USB to get the installation started (sorry I can't post links yet...) forums.mydigitallife.net/threads/7126-The-Official-Windows-7-Repository 3. Download and unpack Daz's loader and put it somewhere easy to find. forums.mydigitallife.net/threads/8632-Program-based-Windows-7-loader 4. Activate Windows 7 with Daz's loader and reboot. 5. Restart and you will see a menu with a list of options. Just select the first Windows 7 option. This will be selected automatically if you don't touch the keyboard. 6. Verify that your Win7 is successfully activated. Follow section 6.E. in the guide from #2 above. 7. If your activation was a success, restart Daz's loader and UNINSTALL it, but DON'T delete anything. 8. Insert your Ubuntu disc or USB into your PC. Reboot. Remember to select the correct boot device. 9. Install Ubuntu. When you get to the option of partitioning the hard drive, do this manually. I generally install Ubuntu 10.04 on another 80gb partition right next to the Win7 partition. Don't forget to create a swap partition for Ubuntu. Most modern systems with large RAM do fine with a 2gb swap. 10. After Ubuntu is installed, your system will reboot. The new boot loader menu will now show Ubuntu at the top and Windows 7(loader) at the bottom with some other options in between. You can change which one is the default OS in Ubuntu. 11. After making sure Ubuntu is installed properly reboot the computer and select Windows 7 as your OS. Once it's loaded, simply reapply Daz's loader and you are good to go! To make absolutely sure you did it right, follow the directions from #6 above to verify your activation. I have downloaded and installed Window's updates and downloaded and installed Ubuntu updates, including kernel updates, and everything continues to work/stay activated. The only problem I see is if something in an Ubuntu update changes Grub2. However, if you pay attention, it's usually possible to maintain your previous menu functionality even after Grub2 is modified in an update. One last point. This works because Daz's loader is based on Grub, hence why some of the other loaders may not work. Daz's is better anyway.
