I have acer aspire V5-573G, I tried to install Windows 10 on my machine using USB key. I have booted to USB key, formatted hard drive and tired to install it, but it gave me error "Windows cannot install required files. Make sure all files required for installation are available, and restart the installation. Error code: 0x800701E3".
After searching through the internet I found that you need to upgrade to Windows 10 from windows 8.1 and shouldn't do direct install. Then I have installed windows 8.1 pro and then I proceded to upgrade to Windows 10 but after sometime the update failed and restored to previous version of windows and it showed error "The installion failed in the FIRST_BOOT phrase with an error during BEGIN_FIRST_BOOT operation".
Please Help, How to install windows 10.
