Previously, I had Windows 10 installed on my PC. Due to some problems, I thought of shifting to Ubuntu. By following this post, I had downloaded the 18.04.4 version's iso file and used unetbootin to burn it onto a pendrive.

The burn was successful and I could boot Ubuntu in live mode. Thinking everything to be all right, I started the installation process. After configuring the installation, a message was shown that We're sorry, Ubuntu installer has crashed. Then when I tried to check the disk for errors from the boot menu, it said that error found in 1 files. It's most probably the casper/filesystem.squashfs file that's causing the error. enter image description here

Now I don't have even the Windows OS because in the process, my HDD got formatted. It's my mistake that I don't know much about disk partitioning. What to do now? I am still able to boot into the live mode from the pendrive, only problem is that I can't save anything to disk. Can I burn a new ISO to that pendrive from this live mode?

I have now successfully installed Ubuntu and checked that everything is working perfectly. According to me, either there might have been a problem in the downloaded iso file or the UNetBootin software. Then I had redownloaded the iso and used Universal USB installer to install it.

For those who will be installing Ubuntu, I have some advice for them to prevent any problems :

  • After downloading the iso file, check whether the file have downloaded properly or not by matching the checksum. See this https://ubuntu.com/tutorials/tutorial-how-to-verify-ubuntu#1-overview

  • Before installing Ubuntu, select Check disk for errors from the boot menu to check for errors in the installation media.

  • Install Ubuntu on a separate partition in the main disk to avoid any data loss.
