Hi, i thought id share my experience. I have a A150, 160G, 1.5g ( mod ), Dell1390 ( mod), touchscreen ( mod)! :p As you can see since i got it i have modding it a lot to fit my needs. I first installed osx in the entire partition to see if i could live with the issues of not sleeping and no card reader, and yes i can, also OSX is very fast in my system, so i decided to go dark side and triple boot the thing. I read a lot and people say mbr, efi, hfs+, fat, af, all this acr that we just love and i thought i'd try a simpler approach, its called, lets see if/how it works. So i started with a fresh install of osx. I Used this tutorial ( thx guys ), to install the osx. [URL]http://forum.insanelymac.com/index.php?showtopic=129774[/URL] Except that i did the following in the step 6 of the above: I have separated my Hd in 4 partitions: 1 OSX = 80 G HFS+ 2 Linux = 25G FAT32 ( dont worry ) 3 Win = 25G FAT32 ( dont worry ) 4 Common = 30G , this reminder i did it so i could easily share files between all three OS'. And so on i continued with my install and update of OSX. After everything was ok, i restared, made sure it would come back to OSX, all beautifully setup. Proceeded to install Windowz. Windows you know, usual, just make sure you place it on the right partition and quick format it with FAT32. After the setup restared the machine i had a disk error problem, im not sure what was it but it displayed the boot for the windows with two options for the same windows installation, the first option did not work and gave me a disk error but the second continued the installation. Ah, you might also get the windows install ( before this ) telling you that needs to mark the windows partition as active for the installation, but you dont have many options as it will do it anyway. Ok i finished installing windows, got in the sytem and ok, restarted with the linux disk. Press F12 to select the DVD drive and boom, lets go live installation of Linux 8.10 During the install make sure you know what you doing during the partition steps ( use manual ), select the 2nd partition you created, use ext 3 with journal system, mount it to "/". and proceed. After it finishes the fun will start. Now was the part where i had most of the problems but thanks to a bit of googling and all of you great community that writes in the posts ( and hey im here too ), i got it fixed easily. Lets make it simple as i said. So having the 3 OS's installed confuses the boot loaders so when i restarted i got the GRUB without the MACOSX option ( expected ). So i knew i would have to edit the GRUB menu list to reflect OSX, so use this: [URL]http://forum.insanelymac.com/index.php?showtopic=85508&st=0&p=606752&#entry606752[/URL] After you do that, you will be able to ( given you edit the menu.lst ) select the 3 OS's from the GRUB boot list. VOILA! There you go, triple boot without complications. Now going foward i wanted to have rEFIt working on, i installed in OSX but nothing comes up when the machine is restarted, so im not really sure as of why, and i dont care much for now, if you have any suggestions they are much appreciated, but if not, life goes on and i will figure it out sometime. I am updating my Ubuntu now ( im writing this on my mac mini ), wireless works fine under ubuntu first shot. Ah, the best part is the touchscreen works on all three systems :D Have a wonderfull and safe holidays!!! Fred
