I've an Acer Aspire 5630 with (Windows XP) and few months back I installed Windows 7 as the second Operating System. After that Acer recovery progarm key (Alt+F10) was not functioning. Last week I format "C:" drive and removed Windows XP. But the hidden partition containing recovery programs is still there. However, Alt+F10 is not functioning. Please help me in loading the recovery program to load Factory default programs.
