Use Ventoy
Ventoy is the best graphical tool for making bootable flash drives currently.
Use the Command dd
or cat
You can use
dd if=path_to_linux_image of=path_to_device bs=4M; sync
or
cat path_to_linux_image > path_to_device
to write a hybird Linux image into a flash drive.
Note that you
must use the whole device
(e.g., /dev/sdb
)
not just a partition (e.g., /dev/sdb1
)
on the device.
For a non-hybrid Linux image,
you can make it hybid using the following command
if it uses isolinux/syslinux technology.
isohybird path_to_linux_image
Be very careful when you run the above 2 commands
(dd
and cat
)
,
as they will erase the whole target device you specify.
Accidentally providing a wrong device will make you lose all data on it!
Use the Command zcat
This is an even more manual way, which is not recommended.
- `zcat boot.img.gz > /dev/sdX
- Mount the USB stick and copy a iso image to it.
- Umount the USB stick.
Use the GUI Tool UNetbootin
-
Ventoy is a much better tool than UNetbootin now. Please use Ventoy instead.
-
If you create a boot flash drive for Ubuntu in Windows using UNetbootin or other softwares, then you'd better format the flash drive as
FAT
instead ofFAT32
. Otherwise, you might get the error information: "BOOTMGR is missing".
Use the Universal Online Booting Tool netboot.me
Note that you must have an ethernet connection in order to use netboot.me. netboot.me is a fantastic tool for general purposes, but it has problems on some old computers.
