do these steps one at a time and try to boot up...if it boots normally stop running the rest of the fixes they won't be necessary...
..download the following file: rc.iso
....then run chkdsk /r from the rc.iso cd...
if you don't have a burning program that will burn .ISO files go here
and get burncdcc ..a small FAST no frills iso burning program...
NOTE...do not put a blank cd in until burncdcc opens the tray for you
1. Start by clicking on BurnCDCC.exe
2. Browse to the ISO file you want to burn on cd/dvd ....in this case its rc.iso
3. Select the ISO file
4. click on Start
make sure in the bios the cd drive is the first boot device....put the cd in the cd drive..boot your computer....
when you boot from rc.iso you will get a blue screen and it will say setup is loading files...
then it will say its starting windows...
you will get to a screen that says ...do you want to install windows or 2nd choice it to repair windows..
press r to repair...you will get to a ...C:\>.......this is where you type in chkdsk /r
type in chkdsk /r
note the single space before the /
While chkdsk is running, you will see a black dos box... Chkdsk will display the specific stage it is checking as well as the percentage of completion of the stage. You cannot do anything else on your computer while chkdsk is running. When chkdsk is finished, it will automatically reboot your computer.NOTE
this can take a long time to complete..it may even appear to hang or get stuck at a certain % for a couple of hours...then complete...it may even back up and go over the same area...this is normal...let it run...there are 5 stages
DO NOT TURN OFF YOUR COMPUTER WHILE RUNNING CHKDSK or you can have severe problems...
remove the rc.iso cd and reboot...if it does not boot into windows
