My one hard drive got messed up and so I got a new one that has 160 GB on it. Problem is, it is not supported by Windows 98 so I got a burned copy of Windows 2000 Professional given to me by my company. So I hooked up the new hard drive and turned the computer on and it said 'operating system not found' so I decided to put in my Windows 2000 disk but I found that my CD-ROM would not open, it's like it doesn't work anymore! Please tell me how I can put windows 2000 on my new HD and how I can work my CD-ROM. I'm very confused and need some help please, I'm not very good at computer hardware so any help would be appreciated. Thanks!
