So i downloaded opensuse iso on my pendrive with ventoy, but during installation I'm getting errors due to not matching 5SMD code or smh like that, is there a any way to install system to get a fixed iso?
Ventoy is great! Except that it doesn’t fucking work!
Just write your iso to a normal little usb with sd or whatever the distro recommends.
My ventoy keyring has a few extra usbs on it for this exact problem. I just boot something that will work with ventoy and use dd to make one of the extras into whatever it needs to be.
Did you check the MD5sum? If you did (and it actually matches), try using a different media creator. You can use something like Rufus or Fedora Media Writer (yes, you can install non-Fedora ISOs with it, the only extra feature it has is that it will automatically download Fedora ISOs you want). If other media creation tools don't work, try a different flash drive, as that's the next most likely issue.
Did you do a sha256sum or md5sum checksum after downloading the iso file and after copying it to the Ventoy pendrive ? (Linux uses caching for copying. Taking the pendrive out before your system has done a "safe remove" can cause problems)
