Hey I am posting because I get Error Code 13 when trying to boot windows 7 64bit. I am using Daz's Windows 7 loader v1.7.7. When I slect a different method of loading in Grub it then will give me error code 15. I am using Raid 0, could that be a problem? My system is custom built by me. Here are the specs: Pentium Core i7 920 OC'ed to 4.2ghz Thermo-Electric Water Cooling 6gb Corsair Dominator @ 1600mhz 2x MSI Nvidia GTX280s in SLI 2gb Dedicated video memory 2.5 TB Hard drive space (2 TB in raid 0) MSI Eclipse MOBO 1000 Watt Antec PSU Creative Sound Blaster X-Fi Fatality Champion Series I appreciate what you guys are doing, and thank you in advance for any help.
