I have installed Ubuntu 20 alongside Windows 10, then removed Ubuntu and grub issues were also solved, now I am unable to install Ubuntu 20 again.

I am installing through USB and a black screen comes with some lines.

error message

It is when I am booting the installer. Ubuntu is not installed on my system.

  • What brand/model system? What video card/chip? Many need UEFI update, change from RAID or Intel RST to AHCI. Some need boot parameters. And Windows fast start up off. Also if UEFI updated, you may have to redo some UEFI settings you changed. – oldfred Aug 07 '20 at 16:07

  • actually I installed a day before Ubuntu alongside windows 10. Ubuntu was working little bit slow. Then I uninstalled ubuntu but grub issue was there due to which I was unable to use windows...then I made windows bootable file and then repair my computer....then troubleshoot, and command prompt...and wrote these commands: bootrec.exe /FixMbr and then enter...again bootrec.exe /FixBoot and enter....and then windows was loading properly....Now again I am trying to install the same iso file but this image comes..that I have uploaded here. – Navneet Kumar Sharma Aug 07 '20 at 16:45
  • Did a Windows update, turn fast start up back on? Have you updated UEFI? Often SSD also need firmware updates. There are many questions & answers on slow boot or slow system, if that is issue, best to review those as reinstall may not solve it. – oldfred Aug 07 '20 at 17:44

Looks like your installer is corrupt.

  1. Re-download the installer .iso
  2. Check the hash to verify a good download
  3. Re-make the install USB with the verified .iso.
