ntldr shows.no start or safe mode with F8.unable to run disc or floppy to REPAIR or format
HELPYou mean you do not have a floppy or  a CD drive?
What kind of computer is this?

OH, just now saw you are new here!

Welcome to CH.
Please give more information about your system.
What did you do to it yesterday?
How old is it?
A poll?yes i have a disk player & a flppy dr.but i dont have start to click on either one.you can put a disc in but it dont do any thing.an F8 dosent bring up safe mode thanksThank you for posting the additional information. It seems that you do have access to the Internet, or you are using another computer to COMMUNICATE with US here. Just in case you're not sure how the F8 function works, here is a video below that to makes it super easy:

do you understand how to get into your computer's basic setup? This is called the BIOS.
By the way, we STILL need to know the MODEL or type of computer you have and which Windows operating system you are using.

Note to moderator. This is not a poll, it should be sent to the hardware or software area as a problem to be solved

Hint:  Always post the "exact" error message text and/or numbers you're referring to.  You haven't communicated until the other party understands what you meant.  Words matter.  --dahlarbear
