I've tried to upgrade an Acer Aspire Z5801 PC from Windows 7 home to Windows 10 but I've ran into some problems doing so.
After a successful installation of Windows 10, the following occurred:
- During boot, I'd be greeted with a black screen that has a blinking grey-ish dash located in the top left-hand corner of the screen, it'll blink for a bit, move down and then proceed to the Windows logo screen. Here, it would get stuck and sometimes proceed to a reboot where the grey dash screen will pop up once again. After that, it would get to the Windows logo and load up the OS as normal - What does a grey blinking dash screen typically mean? I got this while attempting to install Windows 10 on my previous two attempts, it usually led to the failure of Windows 10 upgrade.
- Complete disappearence of my Wireless Network Adapter. It's gone, nowhere to be found. Ethernet appears fine, but no sign of wireless? I even tried to get a Windows 7 driver and see if it would work, it said it installed but it still doesn't show on Device manager, even if "show hidden devices" is ticked. Reverted back to Windows 7 and it got recognised again. I tried a USB wireless adapter (Netgear wg111v3) and that worked fine. So why isn't the built-in card working?
The Get Windows 10 app said this PC was ready to go. Why say that if it just gives me problems?
