Hello! I've been having a problem installing Windows 7 64BIT on my HP Inspiron, I've tried a Dell Startup disk and the regular Win7 disk. When It gets to the completion, it restarts, then for 5-7 minutes it does Completing Installation then it goes black, then comes back 'completing installation' for 10 seconds then I get a bubble with an Error that last .5 seconds. So I do not have time to read it, then the computer shuts down. I have tried all last night, this morning for a few hours, and this is my last resort. I would love any help, I have looked all over the internet for a solution....nada. Thank You!
