I burned it on XP 32.
Last time I waited few minutes after loading files and language setup window showed up, but windows didnt boot. I tried to fix startup but I get an error saying that I'm not using same version. I also installed Ubuntu so I could use its boot manager, but after choosing to boot 7 my PC restarted.
After that I tried to install it on other PC with similar motherboard (DFI LanParty DK M2RS) and I have same problem so I believe that there is a problem with chipset or SATA/ATA controler. Both motherboards have latest BIOS.
EDIT: I just successfully installed it on one more laptop and it works perfect.
