[QUOTE=roadworker;2734188]And if you have a windows recovery disc instead of a recovery partition,you can try cholla’s fix too…[/QUOTE]
The chkdsk is the same as error check it just takes a right click on the OS hard drive /Tools/Error Checking then schedule for next boot.
Although not the ideal way SFC /Scannow can be ran from inside Windows & even better in safe mode. As roadworker posted the best is to run from the recovery console command window.
roadworker’s other suggestions are also recommended ones.
If you follow the procedure in this link & you don’t need to copy sdelete into it for this to work. It will boot you into a recovery command window from a flash drive.
