I did not remount and check after the dd but only after I loaded slack15 iso.

Using more sensible values such as: “dd if=… of=… bs=1M” will lower execution time tremendously.

This may be due to:
~$: man mkfs.vfat
“…
BUGS mkfs.fat can not create boot-able filesystems. This isn’t as easy as you might think at first glance for various reasons and has been discussed a lot already. mkfs.fat simply will not support it 😉 “

I believe that depends on the size of the required install and the operating system in use. If you’re installing a windows OS I believe NFTS is the desired format, and in other cases FAT32 works. Although fat32 has a size limitation so sometimes you’ll need exFAT instead.

lsblk will show you partitions of drive /dev/sdb
Try to use /dev/sdb1 where sdb1 is the partition of that drive

P.S. If “sudo mkfs.vfat /dev/sdb” gives “Partitions or virtual mappings on device ‘/dev/sdb’, not making filesystem” error, try overriding with -I ( sudo mkfs.vfat /dev/sdb -I )
