Hey everyone, I'm at my wits end with this. I've never had any issues installing an operating system in the past and I'm rather embarrassed it's happened to me with what should be such a simple installation. I have partitioned a 260 gig hard drive. I have windows xp up and running on the first partition and I am trying to install windows 7 on the second partition. My problem is that after I initiate the windows 7 setup, it copies the files over to the partition, expands and then restarts. It gets to the loading screen and then straight away I get the blue screen. The only thing on it is: STOP: 0x0000005C (0x0000010B, 0x00000003, 0x00000000, 0x00000000) I've searched high and dry and some tend to think it's an outdated bios problem, which brings me to my next issue. My system is a HP Pavillion a1320a P4 2.93ghz duo with 2gig of ram, I went to the HP website and downloaded the bios update SP34920.exe and when I tried to execute it (using my admin account, also tried using "run as" and also safe mode) it goes through the motions, I click continue and then it tells me.... You must be logged in as Administrator to install this update. Update has been cancelled (9999). Smooth sailing so far, eh? So anyway, I email HP tech support and they send me the standard text book response back. Clear temp files and try redownloading the file and install. That is supposed to magically work, well, it didn't. I'm unsure whether I need the BIOS update to rectify my install problem. If I can't find any answers here, my next plan of attack will be to whack in a seperate hard drive and see if I can install it on that. Oh, and I ran the upgrade advisor and it tells me my system should be able to run windows 7 just fine (hah!) I'd really like to be able to keep XP, at least until I get 7 up and running, so completely reformatting and installing windows 7 really isn't a choice for me at the moment. Please if anyone can help let me know. Cheers!
