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?

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.

What you can do is re-install GRUB2 manually, as stated here or here.

You also have a choice on boot repair disks, like these.

Q3: How do I configure the GRUB Menu?

Grub Customizer

By default, this software is primarily available on Ubuntu.
To install it on non-Ubuntu distributions, see the following:

Q4: How to dual boot Linux and Windows?

Dual boot installation guides:


  • Windows 10 is technically in almost all cases equivalent to Windows 8/8.1 . Therefore most guides applicable to Windows 10 are also applicable to Windows 8/8.1 and vice versa.
  • 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.
Q5: How do I backup? What backup software to use?

Q6: Installation of Linux fails. How do I fix it?

First make sure the following things are correct.

If you are on Windows

  1. Download the ISO image of the distribution you want to install.
  2. Go to the distribution’s download location, once the download finished completely.
  3. Shift + Right click the file.
  4. “Copy as path”.
  5. Press Windows button + R.
  6. Enter “powershell” without the quotes and press Enter.
  7. Enter following command: Get-FileHash paste-here -Algorithm SHA512 | Format-List. Replace paste-here with the path you copied in step 4, by right clicking into powershell. This process can take some time, so be patient.
  8. Check if the hash output is the same as provided on the distribution’s website.
  9. If it is the same, proceed with further steps. If it is not the same, repeat step 1-9.
  10. Now download Rufus.
  11. Open the program and burn the ISO to the medium of your choice in DD mode (very important).
  12. Optionally, enable bad blocks check, if you aren’t sure that your live medium is good to go.
  13. Once the burn process completed succesfully, retry the installation, once again.

If you are on Linux

  1. Download the ISO image of the distribution you want to install copy the path to your downloaded ISO file.
  2. Open a terminal and execute sudo apt install -y rhash.
  3. Execute the following in a terminal: rhash --sha512 /path/to/file, replacing /path/to/file with the path you copied in step 1.
  4. Check if the hash output is the same as provided on the distribution’s website.
  5. Burn the ISO image, as described here.
  6. Once it is burned, check the hash of the CD itself, as described in step 3, but this time replacing /path/to/file with the path to the actual CD.
  7. If the hash is again the same, then retry the installation, once again. If not, repeat all above steps.
Q7: What is the difference between BIOS and UEFI? How do they work?
