when you can't even boot into safe mode...then a repair is in order...go here
for the how to guide...
we can try this first..
do these steps one at a time and try to boot up in between...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 light blue window with a dark blue band at the top and bottom. or a black dos box depending on on which cd you use... 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
boot from the cd again...
then type fixmbr
no joy ....boot from the cd again...
type in fixboot
nojoy...boot from the cd again...
Type in bootcfg /scan
and press enter
if it says total identified window installs: 1
Type in bootcfg /rebuild
and press Enter...
It will identify your XP installation...type Y
once you see this prompt.
You will be prompted to enter the load identifier...type in Microsoft XP Home Edition or Microsoft XP Professional
depending on whichever version you have...press enter
You will be prompted to enter the load options...type in /fastdetect
and press Enter
Type in exit
and press Enter
remove the cd and Reboot
if the above does not fix it...you will
have to find someone with a retail xp cd of the same flavor you have installed...
IE: if you have XP PRO installed ...then the one you borrow has to be XP PRO
