I have a Lenovo Yoga c940 with eOS dual boot. I cleared the eOS partition using Windows disk management tool and reinstalled eOS on the empty space. I want to do it one more time (for reasons that are not important). However, during boot now, I have multiple instances of Linux boot hard drive (with the same ID). Is there a way to clear the Linux partition, delete all options except windows, so that I can reinstall eOS and have only 2 options, Win and eOS?

  • You may not need to remove and reinstall eOS. This may be something relatively simple. Can you update your question to show a list of all storage devices and their partitions? This will make it easier to outline the next steps 👍🏻

  • Thank you for the comment Matigo. Actually I want to reinstall eOS anyway. I made a mistake during partitioning and the root folder is now full. But now I am afraid that if I clear the Linux partitions with Windows Disk utilty and resize again, I will have 3 Ubuntu UEFI options.

Did you try $ update-grub2 or $ update-initramfs -u?

  • I dont think this will work unless you delete the windows partitions first ... the -u (update) looks for partitions to include for the boot Commented Aug 12, 2021 at 5:34

U can use efibootmgr command to clear the unnecessary entries in your bios :


for usage
