ok heres the story!! I decided to defrag my 250gb hard drive a few days ago and left it running for 2 days. When i came back all i saw was a blank black screen i tapped around da keyboard and moved da mouse about but nothing happened so i thought ok restart the pc. I restarted then scandisk started running so i let it run then the computer restarted again and scandisk ran again i let scandisk run like 4 more times then thought ok this is not right so i thought i had no choice but to reinstall windows again.I booted from CD and I formatted my C: drive and started the copying of files from the XP boot CD. About 30% the copying stops and says that a certain file cannot be copied properly, retry or skip the file. I retried but no repsonse so i skipped but then the next file has the same problem after a few skips or a few retries i get a blue error screen. I tried booting from CD at least 1- times already and everytime the file it stops on is always different but the percentage is always between 30-40%. I ran the recovery console option. used the chkdsk /r then restarted booted from CD and did the format and installation again but still no luck. At this moment i am Formatting C: from command prompt which i accessed via recovery console option. I tried switchin DVD drives, making copies of my xp cd but still failing to copy files. I checked my 250gb hard drive on my mates computer and everything seems to be there i also even check the hard drive that i am installin windows on and it functional i managed to recover some files using a recovery program but all i want now is for me to be able to reinstall windows back on. I have to boot from CD because if i don i jsut get the NTLDR is missing message which i assume has something to do with not having a Operating System.
