If you're a virtual pilot (like me) and want to install your FS software on a new IMac, this post might help you not making the mistakes I did. After buying a new IMac (3,06 GHz, 4 Mb), I installed Vista and fs9 with some add-ons (PMDG-737, FS2Crew and NL2000 scenery) as I had done on my previous mac and 'flew' away. Then I read in a tweak post that fs9 should not be installed in the c:\ disk where Windows and the 'My Documents' folder are located as it would slow down the FS. This posed a problem for me, since I had to create a third partition next to the one bootcamp had created for Vista. I tried to shrink my 300 GB Vista partition using the Vista Disk Manager, but it gave me max 75 GB. Defragmenting with Defraggler took me a day but didn't help. Then I found out about G-parted, which was advocated by many on the internet forums. I downloaded it, burnt the ISO on a disk, booted from it and managed to succesfully shrink the Vista partition to 80 Gb which left 220 Gb unallocated. I then rebooted and ... the windows boot option was GONE .... I could only startup the Mac system.Thereafter I spent hours and hours browsing on the internet and finding very little on this problem. Most FS9 and FSX players seem to install it on the windows partition, not creating a separate one. I tried the following steps:First I booted from my Vista disk, as was suggested on a forum. Tried the recover-option, but that didn't work like it did with others on Vista machines. Then it took me a couple of hours to read about testdisk (which is on the Gparted disk). I started it, put in the commands to recover lost partitions and make the disc bootable again but it couldn't find a problem. Subsequently it took me another couple of hours to read about rEfit. I dowloaded it, burnt it on a disk, booted form it, and .... it recognized the windows boot disk! That seemed to have been the trick. But when I tried to boot from the disk, I got the message the disk wasn't bootable. I then went back to the Gparted disk and expanded the 80 Gb disk back to the original size, but the result remained the same: I couldn't start up from my windows partition. The strange thing was that I could still see the partition when I was on the Mac HD and all seemed well. I posted my problem in the Gparted forum and at the same time kept on looking for answers on the internet.Then after having read dozens of related posts, I stumbled on a short discussion about using Gparted on macs. I haven't been able to find the discussion since and I am not equiped with enough knowledge to understand what was said about the root cause, but it had something to do with the boot partition which Gparted and Mac use different (or something to that avail). After having read that discussion, I re-opened rEfit, took a deep breath and used the partitioning tool. Entered Yes on the question asked, re-booted and .... BINGO the Vista boot-option was there again like before. After having selected it, Vista checked the disk and after a couple of minutes everything was OK again, as if nothing had happened. Thereafter I discovered that my Vista partition was beautifully defragmented and could use the disk manager to shrink my Vista Partition to 80 GB. Made a 220 GB partition with the wizard and now have the three partitions. I moved FS9 to the third partition and everything is working wondeful.So, if you are a fs9/X- and mac-user and want to install fs9/X on a seperate partition (it did improve my FS9 framerate somewhat), I suggest defragmenting your Bootcamp partition over and over until you can shrink it with the Vista Disk manager or some other Mac-tested third party sofware. And if you ever run into trouble using Gparted on the Bootcamp drive, I suggest using the partition tool on rEfit to correct the situation. I hope this helps someone else who happens to run into the same trouble as I did.Dirk
