I have an error message on my computer that says: invalid system disk, replace disk and then press any key.
I am horrible with computers, so I asked some friends and one of them told me how to open the CD disk and take out the disc that is inside. I did that and I restarted my computer again. The same 2 lines appeared on the screen. Every time I press a key, the same thing happes again. I am confused about what to do. The friend who was helping me was talking to me on the phone, so he was not able to see what was going on with the computer while he was helping, so he said he wasnt sure if he was guiding me in the right direction. He said my C drive might be corrupted or that I have a virus. I am using another computer to post this message. Do you know how I can fix this problem? Any help would be appreciated. Thank you.
