When you start your machine , tap the F8 key about every second ( in certain XP versions holding down "CTRL" key does same). This should bypass/abort normal load attempt. When offered choices: Use your up/down arrow keys to select "Safe Mode" & hit ENTER key. Don't worry about visual changes you see: They will revert back to normal at next normal boot. Now Follow This:
Disk/repair (Check Disk) (like SFC)
Left click on My Computer(open)
Right click on "C" or your OS drive if another letter.
Left click Properties and then click Tools Tab.
Left click on "Error Checking"> Check Now.
Left click to enter check mark in BOTH boxes offered.
Left click on "Start".
Computer will have to reboot to begin repairs.
Just leave alone (you're locked out anyway) 'til process finished.
In regular mode will take about 1 Hour (more/less)
In Safe Mode about 2 hours.
If computer normal after process complete you might want to create a new
restore point and Label it POST ERROR REPAIR.
This is based on using an onboard back-up copy of sys
files if copy is ok ( even if current are corrupted).
If copy is corrupted, it may tell you to insert XP or SP2(if patch applied) disk or to indicate location of SP2 info to get new,
clean copy inserted. Good to have disk at hand.
Since this start-up by passes most of everything, many items blocking normal start are not loaded (only absolute minimum are used).
Ok i got a difficult situation. I installed a software that messed up my computer for sure. Now i am unable to open Windows xp sp2.When i start my Toshiba laptop it tells me that windows can't be open because the system file is corrupted. Then it suggest me to run the windows cd to repair that. Everything seems easy but the hard thing is that even when i insert the windows cd in the middle of the file loading it says : *** file unavailable, impossible to setup windows.
So i think it's a virus that doesn't want me to repair it...
my question is: is there anything else i can try?
if not: what is the best way to access my harddrive in order to save my important files?
