I take it you burned both from the same .iso image.
Did you verify both?
Can you tell us exactly how you burned them? The exact command line?
I'd check the checksums of both the image and the two media.
Mount the image or media, then CD into its root, and run md5sum. E.g.
for the image:

0

--------------------------------------------------
cd out and umount afterward.
If you pulled in checksums for the image, you can check the whole image:
--------------------------------------------------
root@hawk:/crc/isos/debian/10.x# sha512sum --q -c debian-10.4.0-i386-netinst.sha512sums
root@hawk:/crc/isos/debian/10.x# fc -s 512=256
sha256sum --q -c debian-10.4.0-i386-netinst.sha256sums
root@hawk:/crc/isos/debian/10.x#
--------------------------------------------------
But that won't work on the DVD or CD. For those, use the md5sum file
on the media.

Does anybody read signatures any more?
