OK, I got a request from someone to tell them how to configure a Dell laptop's Media button to boot 7, and the power button to boot Vista. I thought I might as well put it here, so I don't have to continuously PM people
I haven't tried this yet, as I have nothing to back up my computer to yet,
so please do back up before attempting this.
First of all, go into Vista's partition manager and delete the Dell MD partition (the one around 2.5GB). Next, delete the green partition that appears (entitled free space) so that there is only unallocated space left. Next, you'll need to shrink another partition to have enough space for 7. Once that's done, right click on the unallocated space and format it, making sure to give it a drive letter (I gave it S: for Seven).
Next, with your Windows 7 installation disc in the drive, Shut down your computer. As soon as you turn it on again, repeatedly tap F12, this will give you the option to boot from DVD.
The most important step: Once the DVD loads up, choose Custom installation, not Easy. Make sure you install to the drive you made, not your existing Vista one.
Once all that's installed, boot up Vista again. Have your MediaDirect CD in. Open up a CMD window in admin mode, and type:
E:\dellkit\rmbr.exe DELL X Y
Replace E with your CD drive's letter, X with the number of the partition that you want the Power button to boot up, and Y with the number of the partition that you want the MD button to boot up.
For example, my Vista partition is the 3rd in the list, and my 7 partition is 4th, so I would type:
E:\dellkit\rmbr.exe DELL 3 4
Press enter, and that's it.
However, Windows may fail to boot up, because the MBR has been tampered with, in which case
make sure you have a Vista recovery CD at hand. You can boot that CD and run the command:
fixmbr
to fix the boot problem.
Hope all goes well, please reply to me telling me how it went, but remember to take
a full backup as I have not yet tried this and I do not know how it will go.
