Q1: How do I install Ubuntu, Kubuntu, Xubuntu, Ubuntu MATE, Linux Mint, Peppermint OS, LXLE or any other Ubuntu-based distribution?
See here for a list of guides:
Q2: Linux does not boot. How do I fix it?
When installing any number of Linux distributions alongside Windows, you have to always first install all non-Linux products and at the very end the Linux product you want to ultimately serve the bootloader with. The reason is that the most recent installation overwrites each previous one. In your case Windows has overwritten what Linux has installed.
Before messing around, create a backup of all important data. Once you have verified the backup has completed successfully, do the GRUB2 reinstallation by following each step in a guide carefully and precisely. Don’t skip steps and don’t skip sentences.
Q3: How do I backup? What backup software to use?
