How can I fix my laptop that has missing or corrupt file?
My laptop that is HP aspire one suddenly displayed a blue screen while I'm using it. The blue screen has this error message "System32/Drivers/Ntfs.sys"? But it has some instructions that tells me to press "R" to repair but it just restarts and nothing happen. I put my bootable cd to my cd rom but it doesn't work either. It just restarts continuously and system always stopped and display the blue screen.
How can I fix the missing and corrupt file on my laptop?
Can someone help me to this problem?
