gpart

okay, so I hang on to my version of antix (that offers unetbootin) making a bootable usb-stick, because gpart is dragging me down. And just adding this, I coud go for the commandline like
Code:
dd if=/your/path/distro.iso of=/dev/sdb1 bs=64K

.
That is putting fun back into your distro.
Sure, unetbootin uses all of the media. But thanks, anyway.

It's been more than eight years I have been using CD or DVD media at all, and since I took off the CD-Drive I am really lazy to put it back, just to burn once in a while a CD.

SOLVED at least it works for me.

I may should say this topic can be set as solved under the condition that it works for me.
It is about a usb-stick with an iso-image on it, Made on a linux machine putting a linux-distro on in, bootable device, to test the distro. I did not like it, disarded it, went back to gparted, formatting it as msdos fat32. This worked well, linux tells me, full space available.
The point is, this device goes from a linux to a BSD and rarely to a Windows machine. That is why I needed the msdos fat32 format. While linux says that everything is okay, BSD mumbles correctly, that there still is a boot partition on the drive.

Once again it works for me this way, not claiming the solution for encrypted partitions or slicing and dicing. So this is a particular solution, but probably helpful for others, who are not using encrypted slices or something just made for ufs. Although there is a slice1.


Code:
# clean the whole partition
gpart destroy -F da0

# set a mbr on the same
gpart create -s mbr da0

# fill the partition
gpart add -t \!12 da0

# format ins msdos style (fat32)
newfs_msdos -F32 /dev/da0s1

Resuming, some things take time. Damn thing.

This would or could work for make it bootable for ufs or BSD, I did not try yet


Code:
# clean it all
gpart destroy -F da0

# set a blank BSD partition 
gpart create -s bsd da0

# set the whole partition for usage of FFS(2)
gpart add -t freebsd-ufs da0

# format it (ffs(2))
newfs -U /dev/da0p1

This is an approach for flash drives


Code:
# Think twice about the name of your device
# clearing the MBR
dd if=/dev/zero of=/dev/da0 bs=2m count=0

# formatting it
newfs /dev/da0

# test test test
mount -t ufs /dev/da0 /mnt

# note da0 may, or may NOT be the correct device - check messages

You've managed to make something that is really quite simple very complicated.

To format a USB stick into FAT:


Code:
dd if=/dev/zero of=/dev/da0 bs=2m count=1
fdisk -BI /dev/da0
newfs_msdos /dev/da0s1

It's a good idea to do this any time you buy a new flash drive.

To create a bootable USB stick first CD into the directory the .img file you want to work with is in. (I have also used this method to make a bootable USB stick from a Kali and a Debian .iso file.)

Now use the following command:


Code:
dd if=./distro.img of=/dev/da0 bs=512k

That's all there is to it. You almost had it the first time but were not using BSD naming scheme on your GhostBSD box.

I realize this is an older thread but wanted to clear that up.
