I'm trying to reformat my mom's old Compaq Presario SR1303WM. I've set it to boot from the cd-rom and I almost had it. But after deleting the partitions and starting a clean install it would only load the programs to 20%. After that it locked up and wouldn't do anything. I had to shut down and restart. Now, it won't load from anything. Of course the old OS is gone so it won't start up on the hard drive and it won't boot from the cd. It just keeps going to a black screen with "Error Loading Operating System". Can someone please help me. I know they can't get a new computer and I just want to get a new install on this one to speed it up for them. They had a ton of malware and such on it. Any help greatly appreciated.
