I have an Asus laptop with Win10 installed. I previously had a distro of Linux installed with its own GRUB. Today, I decided to change the Linux distro, but I first checked whether Win10 UEFI was still there. It's not.
I tried unsuccessfully to recover it from Windows. When I rebooted the PC, I started having troubles. It said, "no operating system found" just after the Asus logo disappeared.
I had a CD with Ubuntu and I tried to start a live session to see what wasn't working. All partitions were OK, so I tried to remove other Linux partitions (thought it was a GRUB conflict). I also tried to repair the Windows MBR with syslinux. All I got when I restarted was another prompt-style error message saying "Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press any key".
This is my situation, I have no UEFI to access in safe mode for Windows, I have BCD problems on Windows, and I have no Windows installation CD. The HDD is correctly read in the BIOS menu and is correctly set as the first boot option.
When I was on Ubuntu live, I saw that all Windows files could be read, and all partitions were okay and working. However, I used Gparted and now the file system of Windows is corrupted. I did find another Win10 installation CD, but it is for another type of Windows 10.
What should I do to recover Win10 without loss of data?
