In the end it has let me re-install Windows,It's a bit messy but it works.

Thanks for your thoughts,time will tell if there is a fix.Phil

Well I will have to think of something else .

What i'me after is to run chkdsk to see if it sorts it out.

no not a thing.

Same thing,gets to win screen and re-boots.

Thanks. The machine goes to safe mode start screen then Win screen for about 3 seconds then re-boots.It was caused by power failure .Also I tried the Windows repair disc,and got message that it needed to format the hard drive. I've tried from F1 to F12 but cannot get to command prompt.

Can anyone help?I'm trying to get an Optima computer to boot to commandpromt to run chkdsk.Have tried all "F"keys without success.What can I try.Will not go to prompt in safe mode.
