This issue seems to be isolated to SSDs from doing some basic research. When I try and install windows 7 x64 on my SSD I get the error: Code: Setup was unable to create a new system partition or locate an existing system partition. My SSD can be seen in my PC on the left and I'm running FW v502 I have it in my SATA3 port which is a marvell 91xx controller with AHCI enabled. I tried in IDE mode, in a SATA2 port, also using the specific AHCI driver from the mainboard site. Got the same error every time. I tried the diskpart commands from here: http://www.overclock.net/t/1156654/seans-windows-7-install-optimization-guide-for-ssds-hdds Also did nothing. any ideas? The only way I was able to get it installed in the past was installing from within Windows installed on my old HDD already. I just want it to work I'd even be willing to buy a SATA3 HBA card if it was guaranteed to work.
