Hi i downloaded WinSetupFromUSB.exe and installed it on my Windows Vista HP Compaq Laptop what i did was i chose the destination of WindowsXP. and then, i formated the 2GB Kingston USB Flash Drive using HP Format Tool. then after that i press on Start. after that i restarted the laptop and the BOOT screen for WindowsXP started. i chose the first option, then it went back to the boot screen again with a second option, here are two things that i did 1. I chose again the first option it went to a blue screen (like the WindowsXP Installation Screen) when i went on the C:\ Drive it only has 1.9GB (which looks like my USB Flash Drive Capacity, and it does not contain my Main Hardisk, so what i did was i chose Drive C:\ but it went into an Error Screen saying that its corrupted.. F3 to Quit. then i restarted the computer. it says that its MISSING OPERATING SYSTEM 2. I chose 2nd option but it says that its missing a file.. (forgot what file it was though).. anybody can help? thanks a lot. this is for my ACER laptop. it has a defective CDROM Already so im looking for another way to install Windows XP in it. thanks

I have a HP Compaq CQ40 310AU and currently its running on Windows Vista Ultimate 64-bit (which is very very slow) I want to downgrade it to Windows XP but everytime i try to Boot using the Windows XP Installation disc. it freezes up on the "PRESS ANY KEY TO BOOT FROM CD" i have already tried 3 CD's but unfortunately it does the same thing. i tried using the CDs on my other laptop and my desktop and they work fine. but when i try booting up using the Windows Vista Installation Disc. it boots up ok. any idea on what i can do? thanks a lot
