Ubuntu not booting and initial ramdisk not loading

[bob466]

Well we seem to be getting nowhere fast especially when the OP says he/she is entering commands in Grub...how do you run commands in the Boot Loader.

OP has an old windoze computer...download the windoze version of Ventoy...install it to a Flash Drive of 8GB or more.
Download the Mint ISO (Mint would be simpler)..then drag the ISO into Ventoy and with secure boot disabled boot to Ventoy and install Linux Mint 22.3.

I agree. Posts #15 & 16 headed off in that direction, but then it all goes to hell in post # 17
