I too faced a similar issue once and then read the manual on Acer Website and then when i used to face problems with my Windows XP Home partition, I used to either reinstall Windows from previous back-ups or reinstall it fresh by pressing Alt+F10 keys. I purchased that laptop in 2006 and recently i had to discard Windows XP completely as the HDD is not working properly owing to overheating.
The HDD of my laptop is 40GB and cannot be replaced unless it is available. A technician saw my laptop and told me to service its parts and put oil to make the HDD work properly without heating up. Recently, owing to much of such problems i removed Windows XP and installed Ubuntu 14.04. It runs smooth and does not require forced shutdowns through manual power offs.

The hidden partition contains recovery software called NORTON GHOST ( in my laptop it was present), how ever it may differ as per configuration and price. I removed my Windows XP completely substituting with UBUNTU Desktop 14. Download Pokemon Emerald 386 Rom Zip. 04 because Linux is more stable and less vulnerable to virus attacks. Please do not go for UBUNTU if you do not need and if you do not know how to use it.
