This blog post is going to assume that we're writing to `/dev/sdX`. Please change this to whatever disk you're actually trying to write to. I bear no responsibility if you accidentally write to your OS drives.
|
||
|
|
|
||
|
|
Make sure the disk you wish to write to is unmounted.
|
||
|
|
|
||
|
|
```bash
|
||
|
|
sudo umount /dev/sdX
|
||
|
|
```
|
||
|
|
|
||
|
|
For good measure check `lsblk`....
|
||
|
|
|
||
|
|
Then perform the writing operation
|
||
|
|
|
||
|
|
```bash
|
||
|
|
sudo dd bs=4M if=/path/to/distro.iso of=/dev/sdX conv=fdatasync status=progress
|
||
|
|
```
|
||
|
|
|
||
|
|
`fdatasync` will wait until the data is physically written into the drive before finishing.
|
||
|
|
|
||
|
|
Once that operation is done we can check to see if it is performed properly. This step will only work for ISOs that have prepared a file similar to `md5sum.txt` that Ubuntu provides....
|
||
|
|
|
||
|
|
```bash
|
||
|
|
sudo mount /dev/sdX /mnt
|
||
|
|
cd /mnt
|
||
|
|
md5sum -c md5sum.txt
|
||
|
|
```
|
||
|
|
|
||
|
|
Hopefully you'll see all `OK` and we're good to go!
