Help with booting my device

[mahesh]

So recently i have installed Ubuntu on my LENOVO IdeaPad Duet 3 10IGL5-872 with Intel Celeron N4020 - RAM: 4 GB - 64 GB eMMC - Intel UHD Graphics 600 hibrid laptop and my first boot was completely fine. But when i tried to do a second boot something happened to the system and i can not boot into the laptop. Plus whenever i boot from the flash drive it tells me that there's a file missing and that might cause some errors.
Here is the the link of the boot repair that i did from the live USB---> https://paste.ubuntu.com/p/Tqm5T8jsd7/
