I am in need of some help with a win 7 installation. I bought an older HP Compaq desktop with no hard drive ... 240 W BTX power supply - Active PFC Intel Core 2 Duo E7600 Processor (3.06-GHz, 3MB L2 cache, 1066 MHz FSB) HP 4 x 1 GB PC3-10600 (DDR3 1333 MHz) DIMM I tried to install Windows 7 Pro 64 bit SP1 and it keeps hanging at the startup logo. I bought the machine without a HD and am using an old 80 gig Maxtor Diamondmax plus 9. I downloaded and burned a disk using Startup Disk Creator that comes bundled with Ubuntu. I did a sha1sum check and verified the disk after. Actually I made 2 disks since I couldn't get the 1st one to install either. The first time I tried it went past the point where the logo is displayed and I entered country etc but when I got to the part that asks where to install I realized the drive wasn't detected. So I went back and reconnected the sata cables and checked the bios to confirm it was being recognised. I'm not sure that I have the right windows Iso but I did install Win 7 pro 64 bit SP1 on an identical machine I bought a week before and it installed and activated flawlessly. Really could use some help.
