* bootable-usb: Add extra caution about unmount Not unmounting an USB partition before an image is burned could cause file system checksum errors leading to other issues (including kernel panics) when trying to boot from the USB drive. This commit adds an extra caution note to warn the users about the possible issues they could find when this step is not followed correctly. Signed-off-by: Jair Gonzalez <jair.de.jesus.gonzalez.plascencia@intel.com> * bootable-usb: Add o_sync to the dd command Update the example 'dd' command to burn an image, by adding the 'oflag=sync' option. This allows to reduce the flashing time in conjunction with the recommended 'bs=4M', enables a more accurate progress indicator, and allows to remove the additional sync command, while preserving some cache optimizations.

content. Back up your data before proceeding.

Not fully unmounting the USB drive before burning an image could cause

file system checksum errors in it. If this happens, burn the image again

ensuring all the USB drive partitions are unmounted first.
