Hi Ram,In case you plugged your media at any time on a Windows system, please be aware that Windows automatically creates a 'System Volume Information/' directory, along with a bunch of small files, on any file system it can handle, which would include the FAT16/FAT32 file systems typically used by an ESP.
The end result of this is that, for media such as Debian that includes an ESP in the form of an 'efi.img', validation checks of that efi.img file are likely to fail if the media was ever plugged on Windows...
Now, I see no clear hint from your testing that you used any Windows host in the process. But I thought I would mention that just in case.

Unfortunately I don't have one at hand, and there are none in the stores here. The only option seems to be to order one online, which will take a few days to ship. When I get the disks, I'll test using the installer with them. Thanks for the help! Have a great day; Ram
