[QUOTE="Dieter3, post: 1632466, member: 201904"] Hello All, I have what I think is a very odd problem, but probably stems from my understanding (or lack thereof...) of Apple's fusion system and/or Bootcamp. Machines in question are iMac 14,3 that originally had the 1.1TB Fusion drive (128GB + 1TB). The 1TB drives are slow rotational and only SATA II even though the bus is SATA III. Win7 under Bootcamp booted very slowly as a result and general performance is lackluster. Need performance over space, so removing the 1TB drives and replacing with SATA III, 240GB SSDs. - WOW. Goes without saying, but NOW they jam. PROBLEM - Installing Bootcamp destroys the OS X partition, and formats the 128GB SSD as MS-DOS!! Huh. So, here's my process - HELP! 1) Boot in recovery, use terminal app to determine and destroy logical volume group. 2) Install OS X Yosemite from Apple on the 128GB SSD card. 3) Disassemble machine, install 240GB drive, reassemble, boot. 4) Run Bootcamp - gives a couple of options at this point - to create a partition on the 240GB drive or use the whole drive - EITHER OPTION = destroyed OS X partition. 5) What I have been doing is setting the Bootcamp partition size to 160GB so I've got a spare partition to use for data excess. 6) - Windows installs just fine (after telling setup to format the drive as NTFS) and runs perfectly. But as stated - OS X is destroyed at this point, only the 10.10 Recovery Partition comes up if you hold down Option at boot, with Windows. 7) Boot from external HD with OS X, run disk utility to reformat the 128GB as OS X ext.journaled, and re-image the drive. 8) - NOW OS X and Windows co-exist happily together. But what's up with that? This has never happened to me on a non-fusion Mac. So, I've gotta be doing something wrong, out of sequence, or otherwise as it relates to the fusion system. Any suggestions on a different way to do this process? Thanks all. [/QUOTE]
