Thanks for the Easy BCD explanation! I got the Dual Boot loader working... but not OSX. When insterting iDeneb 1.4, I press f8, and put -v; Then it stops saying this:

Waiting on <dictID="0"><key>IOProviderclass</key><string ID="1">IOResources </string><key>IOResourceMatch>/key><stringID="2"> boot-uuid-media</string></dict>
Here is a screenshot: http://i156.photobucket.com/albums/t...g?t=1246351912

I searched this problem, but couldn't find any working solution:
I tried using JaS.OSx86.10.5.4.Client.Server.Intel.SSE2.SSE3 distro... same result

Tried booting with several commands (-x -v, -f, -s, -x, etc...)... same ending

Tried disabling USB legacy support in BIOS, but afterwards my 2 keyboards didn't work when boot says "press any key to continue installation or press f8..." and time runs out... and i'm obliged to type a command... I didn't try with PS2 keyboard but I saw that OSX doesn't support them... But in the BIOS and in Windows keyboard and mouse work perfectly

On another forum, someone said to extract one of the RAM cards so that you will only end up with 2GB.. I did this and boot freezes at another point of the log, saying:

Extension "com.apple.driver.ApplePCIconfigurator" has immediate dependencies on both com.apple.kernel and com.applekpi components; use only one style

This message also appeared when I tried before... but it just continued (see image)... but the weird thing is that it only happened once... I reebooted PC, (still with only 2 GB of RAM) and I got up to the first message instead of this one... So I inserted again my 2nd 2GB RAM card

I searched here for my problem... but didn't find anything which contained "Waiting on <dictID="0"><key>...<stringID="2"> boot-uuid-media</string></dict>"

On the saw a compatibility list on a wiki for OSX x86 10.5.6. My motherboard doesn't appear, but sever motherboards appear which contain my chipset (Intel G31M) so I thought i'm still might have a chance to install OSX

Is there a good known solution for this?
Thanks, Hugo
