I've tried to create installation media on both a DVD and a flash drive, without success. I've done my best to follow the instructions, but I imagine that I've missed a step somewhere, so I'd like to review my procedures with the learned people of this forum.
My steps in trying to create a bootable DVD:
1. used jigdo to obtain debian-8.7.1-amd64-DVD-1.iso
2. used brasero to try to burn the image to a blank DVD
3. got this error message:
mount: /dev/sr0 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/sr0,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so.
When I did the dmesg | tail, I got this:
- Code: Select all
mzimmers@debian:~$ dmesg | tail
[ 2304.226170] UDF-fs: warning (device sr0): udf_fill_super: No partition found (1)
[ 2304.242089] sr 2:0:0:0: [sr0]

[ 2304.242117] isofs_fill_super: bread failed, dev=sr0, iso_blknum=16, block=16
Most of that is Greek to me, but I notice the "no partition found" message. I'd have thought that brasero would take care of any necessary partitioning for me...not so?
When I copied to my flash drive:
- Code: Select all
dd if= debian-8.7.1-amd64-DVD-1.iso of=/dev/sdc
and then went to the boot menu in my start-up, I saw two 16GB devices listed. I wasn't expecting this, but I tried them both. When I selected the first, I got nothing; when I selected the second, I went into a GRUB menu. (My GRUB is sort of messed up; I'm dealing with that in another thread.)
Any suggestions? Thanks...
