+If Mageia comes with grub2, I am certain it will install alongside 
+Windows 7 with your confirmed GPT partitioning and in *either* BIOS *or*
+UEFI mode. The problem is that no one here can vouch that Mageia's 
+grub-legacy can handle this. (Though we hear from Thomas that his Fedora 
+16's grub-legacy could; Charles' single OS drive setup and Olav's claim 
+that he has no problem on MsDos with (u)EFI)
+
+Here, I think it is good to remember that some of these "transitional" 
+motherboards have 'fake' UEFI (to simulate UEFI) and EFI (an apple 
+thingy) is not UEFI. "Pure" UEFI requires GPT partitioning. Period.
+(BIOS can handle both). Oh, before I forget (again), UEFI *requires* 64 
+bits.  But we should thank Thomas, Charles and Olav for their input.
+Thomas has his working fine and it is one area we can explore later on 
+this post.

+What we can do (a workaround, no doubt) is to install another grub2 OS 
+or Thomas' F16 to run alongside your Windows7. Than we install Mageia in 
+another partition and have the other OS grub2 (or Thomas' F16 
+grub-legacy)  pickup and bootup your Mageia.
+
+
+If you choose with Thomas F16, Thomas will have to come in to help you 
+with it and of course a safer bet is to use Charles' single OS drive 
+(that way, you get back whatever we mess up).
+
+The choice is for you to make with the corresponding risks.
