How? I plugged my USB Flash drive with Wintoflash Windows 7, clicked the Autorun, but It cannot fully delete the Drive C and D unless I boot my laptop using the Windows installer in my USB flash drive.
Do you have a windows install dvd/usb? You are going need to reinstall windows after you format your system hard drive. Just go to BIOS and select the dvd/usb as boot disk. Start the install and format C: and D: from there. You should have no problems.
I searched on the net and I found out same problem with other people. I did a system recovery (just like him) and the Acer eManagement Recovery (which I think is used to reformat an acer laptop) is gone afterwards. I cannot find also the Acer folder which is supposed to be found in start menu.
