Re: USB Install Fails, Complains about CD-ROM
Hi Kent,
After doing the cp or dd to write the .iso to the USB, do you do a “sync” before you eject it? Writing to a USB stick can seem to go quite fast, but that’s because of buffering. Often it takes quite a while (a minute or more for a very big write on a machine with plenty of RAM) to clear the buffers and write thru to permanent media.
Just a thought,
Rick
PS: Here’s what I use to write a .iso file to a USB stick:
dd if=/debian-live-9.4.0-amd64-mate.iso of=/dev/sdc bs=1M conv=fsync status=progress
sync
eject /dev/sdc
Hope it helps!
