I have a ASUS X552M laptop with Windows 8 running on it, I wanted to install Ubuntu in dual-boot. However, the installation froze so I had to restart my computer, then I couldn't boot Windows I got PROCESS1_INITIALIZATION_FAILED error, I tried to work around this by deleting the bootcat.cache file or disabling the secure boot option, none of this worked.
So I backed up my files from a Ubuntu liveUSB and wanted to restore the laptop to factory settings. So I tried hitting the F9 key and choosing restore system. Now, I got a message to insert a Windows installation disk but I got none, I have a 20GB partition called RESTORE for this situation but I can't access it, it asks for an installation disk. I was trying to look for a solution but I only got to something called ASUS Backtrack, now I don't know how to use it in my situation, it's a windows application but I have no way of starting it.
I'd appreciate any advice I don't know how to proceed now.
Can I use a Windows 10 installation media if my laptop was shipped with Windows 8 but immediately upgraded to Windows 10 after start-up? – David – 2016-12-29T11:00:45.003
Now just after starting the installation I get: "Windows could not prepare the computer to boot into the next phase of the installation. To install Windows, restart the installation." – David – 2016-12-29T12:02:19.250
