Hey guys. So here is the problem. I recently acquired a old DELL Precision 450 Series Workstation, its pretty old but still works fine. Anyway I also have a laptop which is my secondary computer and I took the 2.5 HDD out of it and then plugged it into a sata to usb 2.5 hdd adapter, most of you know what it is so yeah. So when I changed the BIOS boot order to boot to USB, everything goes fine, until the OS tries to load then I get one of the famous Windows boot screens, Windows cannot boot blah blah blah this could be due to a recent hardware or software change. please insert your windows installation disk. I dont have the disk anymore so I went around on the web and found and trustworthy site to download an ISO, I then used the windows 7 usb/dvd download tool to burn it too a disk. heres where the problem is, I dont even think it is recognizing the disk, I tell it to boot to the IDE CD/DVD drive and it just black screens and tells me to retry or go to the setup utility, I have tried it with two working cd/dvd drive and I really can figure this out, I am running Windows 7 Home Premium 64 bit.
