I installed the new hard drive I bought ( an SATA drive, 2 terabytes), and I took out the hard drive that was in the computer, (320 gb). I formated the new hard drive by using the driver disk I got with the computer, and I re installed the os. First it said that NTLDR is missing, then it said NO BOOTABLE DEVICE IS FOUND, INSERT BOOT DISK. Then the blue screen came up saying windows is shut down to protect your computer ..... I tried going to the command console and typing BOOTCONFIG /REPAIR, and it said file cannot be repaired (I'm not sure if that was the wording). I repeated this several times with every system disk I have.
When I tried it with an OPERATING SYSTEM DISC for windows xp media center edition 2005, it loaded and started, but it said the hard drive was only 70 gb, it said it was an NTFS file system, (I think it was NTFS) there was only one drive listed, (C drive), and all of the other specs were completely wrong, and there was no sound. I formated the disk again, and tried to repeat loading one of the other os disks I had again, and I got the missing NTLDR, AND NO BOOTABLE DEVICE, and the blue screen again. Thank you in advance for any help you can give.
