Hello! I got Windows 7 32-bit on my computer at the moment, but I want Windows 7 64-bit. I've checked the Windows 7 Upgrade Advisor and it said I could run Windows 7 64, but I had to do a clean installation. And there's where the problem is. A time ago I changed boot menu to "boot from CD", and that was a pretty long time ago. I inserted the Windows 7 64-bit CD into the ROM and restarted me computer. During boot-up it said "booting from CD, push any button to continue(or something like that, I got my Windows on Swedish, so it might not have been the exact translate)". But, when I try to push ANY button nothing happens! I can't even get into the BIOS, but since I've been there earlier it should work, it might be a setting. Anyways, my PC is fully compitable with the Windows 7 64-bit version so there shouldn't be a problem. And the keyboard is Microsoft Sidewinder x6 (their own product!!!!)It's USB. My system is fully up-to-date! I appreciate any help I can get!
