Hi everyone,
I experience some weird behaviour with the FreeDOS ISO
I flashed FreeDOS to an USB.
when i plug the USB in i can open the partition and browse the FreeDOS
directories
However, when i tru to boot the drive the Acer does not detect it.
Then i tought, to flash it againg but then by usin Unetbootin.
BUT Unetbooting does not detect the USB either
So i look with Gparted. and when i select the drive this-one says
UNALLOCATED SPACE
Then back to MKUSB.. BUT MKUSB no longer sees the USB
But in PCman i can just browse the drive withouth issues..
I don't understand what happens. Maybe you can run some commands and
post the output in a reply.
- Run the system, where pcmanfm can see the drive with FreeDOS
- Open a terminal window
- Run the following commands and post the output (copy and paste to an
email window),
df -h
sudo parted -ls
sudo lsblk -f
sudo lsblk -m
Then i installed the Diskutillity from gnome
And thisone sees the USB but it can't remove or edit the partition.
So back to Gparted, this time Gparted does NOTsee the USB.
back again to diskutil
unmounted and remounted the partition
back to gparted and now it again sees /dev/sdb as unallocated diskspace.
Warning: /dev/sdb: unrecognised disk label
Is there something that i'm missing? Something that diskutil can do that
gparted can not? And MKUSB why does that no-longer see the USB stick?
Try to remember what you have changed in the computer, for example some
setting in a BIOS menu.
Can you see make the system see another pendrive (with some other content)?
Is there anotherapplication then Diskutilliy or Gparted that is able to
at least let me remove the partition and format the stick?
What happens in another computer?
I'm sure i'm overlooking something.
What happens after shutting down, waiting for 5 minutes and cold booting?
The unrecognised disklabel is that caused by the FreeDOS iso or could it
be a bug in MKUSB?
I'd like to try to flash FreeDOS with Unetbootin but cant figure out why
Unetbootin does not see the USB at all.
Read about FreeDOS at its web page, and use a method and tool that is
recommended to install it into a USB pendrive.
For example this page
https://www.chtaube.eu/computers/freedos/bootable-usb/
suggests to first expand with bzip2 before flashing. mkusb is made to
expand files compressed with gzip and xz (but not bzip2), so you must
use it in a two-step procedure, first expand, then flash alias install
into a USB drive.
So check with sha1sum, that the download was good,
sha1sum FreeDOS-1.1-memstick-2-2048M.img.bz2
187ce046066b7a70039a46d7c3a24dd52a8dc049
and create 'FreeDOS-1.1-memstick-2-2048M.img' with the following command
bzcat FreeDOS-1.1-memstick-2-2048M.img.bz2 >
FreeDOS-1.1-memstick-2-2048M.img
and use it with the following command
sudo -H mkusb FreeDOS-1.1-memstick-2-2048M.img
in a computer, where the target pendrive is recognized.
You can also use dd or some other tool to get it into a pendrive by the
*cloning* method. Do not use Unetbootin.
