Greetings, I downloaded the RTM 64bit ISO and put it on my USB drive, rebooted and wanted to install it as secondary OS. The setup went up to the install type dialogue, I chosen custom install since I don't want to upgrade from existing Windows version. In the custom partition list I've chosen the 2nd partition on internal HDD which I prepared as 26GB big NTFS filesystem with default cluster size. Surprisingly the setup said it can't install it there without explaining why, with reference to see some setup log. Where is the log located, and what is wrong? The setup even refused installation when recreated and formatted the target partition using setup partition tools. It looks that the partition is OK but there's something else preventing setup from finishing, I need some more detailed information. I already have installed Win7 activated with BIOSmod and it works without any problem. Thanks for any guidance.
