My new Desktop computer does not have a DVD/CD drive so I will have to
install MGA 9 on to the SSD via a USB Drive. Never done that before so
is it just a case of copying the ISO file from the old Laptops HD on to
a USB drive (5GB or bigger) and then inserting that USB drive into one
of the USB sockets on the new Computer and THEN booting the Computer

Might I have to get into BIOS and tell it to check for a Bootable USB
drive .... or might that be the Usual operation??

(A task for the week-end, maybe.)

TIA

For most 'standard type Micro based systems' you will have to :
1. Set via bios to offer BOOT from HDD, SSD, USB & CD/DVD
Warning leaving this on at all times will result in a slower boot
process as bios will check what is available (subject tot he bios used).

Or

2. Optionally set bios to boot to specific device when needed other than
HDD/SSD.

Or

3. As a one off boot to specific device.

4. Boot to a network device which can be off site, such as a network
install but this usually requires a local storage devise to be used for the
initial s/w load.

As a rule and to reduce boot times option 3 & poss. 4, tends to be used.

Not all system allow you to specify a USB device (although my kit that is
now over 10 years old does) and likewise using a CD/DVD and a DLT device.

Both could be refused due to security settings.
Mine is set to Not allow remote booting of any kind, i.e., only local.
Ditto the O/S will not allow root login remotely for the same reason.

Remote mean anything that is not from the system console (keyboard, monitor
etc).

Yes this does mean that if away (holiday, etc) you cannot reboot the system
but there are other processes to do this if prepared in advance).
I turn off automatic upgrades when I will be away to help prevent s/w
induced problems of this nature.

How to boot from the usb drive varies from computer to computer. You may need to do it
from the bios setup screen, or use the bios setup to enable it.

Unless it's a very old system, it will be using uefi. See
https://wiki.mageia.org/en/Installing_on_systems_with_UEFI_firmware#Using_a_USB_stick

The package isodumper is made for safely copying Mageia iso images to a usb stick, so if you
already have Mageia on one of your systems, install isodumper and use that to copy the iso
to the usb stick.

Forgot to mention. Some systems will only show the option to boot from a usb drive if a
bootable usb drive is currently plugged in, so copy the iso to the usb stick before and have
it plugged in before looking for the option.

Seems point 2 (Dump the ISO to the USB stick, using either IsoDumper or
the dd command. More information here.) is what I want.

The package isodumper is made for safely copying Mageia iso images to a
usb stick, so if you already have Mageia on one of your systems,
install isodumper and use that to copy the iso to the usb stick.

Ah!! O.K., so can I extract 'isodumper' from the MGA9 iso that I already
have on the Laptop and then use that 'isodumper' to dump the MGA9 iso
onto a USB stick??

Thank you, David.

the dd command. More information here.) is what I want.

If you want to use dd, use "dd if=/path/to/iso/file.iso of=/dev/sdx bs=1M". The critical part
is to replace /dev/sdx with the correct value for the usb stick. Put in the wrong value and
you may end up overwriting the partition table on your hard drive.

Make sure it's a block device like /dev/sdf, not a partition within the device like /dev/sdf1.

The dd command may appear to finish while the usb stick is still writing the iso from
buffers in memory. It's critical to ensure it's finished before rebooting or removing the
usb stick. Before isodumper I used htop sorted by the S (state) column, and waited
until at least several seconds without any kworker process showing a state of D
(device wait).

If you don't have htop, and are just relying on dd, a good rule of thumb is to wait 10
minutes after you think it's done.

The isodumper program will only allow choosing a usb stick, not a hard drive, and will
ensure the writing has finished. If you've downloaded the sha3 file for the iso image
into the same directory as the iso image, then isodumper will check that the iso file
has the correct value, ensuring the download has not corrupted the file.

It can also check the gpg signature of the sha3 file, if you have imported the Mageia
iso signing key into gpg.

It isn't included in any of the iso images. It hast to be installed from the repos in an
existing Mageia install. If you don't have an existing Mageia install then you will have to
use dd itself.

If you have Mageia 8 currently, isodumper is available ...
https://mirror.math.princeton.edu/pub/mageia/distrib/8/x86_64/media/core/updates/isodumper-1.35-2.mga8.noarch.rpm with either
https://mirror.math.princeton.edu/pub/mageia/distrib/8/x86_64/media/core/updates/isodumper-gtk-1.35-2.mga8.noarch.rpm
or
https://mirror.math.princeton.edu/pub/mageia/distrib/8/x86_64/media/core/updates/isodumper-qt-1.35-2.mga8.noarch.rpm
for the gui front end.

The gpg release signing key can be obtained from one of the pgp public key servers such as
https://pgp.mit.edu/pks/lookup?op=get&search=0x835E41F4EDCA7A90
(note very slow, but it does work. Or you can extract it from below ...

$ gpg -a --export 0x835E41F4EDCA7A90
