Hi,

Do you have Syslinux installed?

V.

[jsmeix]

@celikozl
in general you may also have a look at things like
http://relax-and-recover.org/documentation/
and
https://github.com/rear/rear/blob/master/doc/rear.8.adoc
and
https://raw.githubusercontent.com/rear/rear/master/usr/share/rear/conf/default.conf
therein in particular the [U]EFI config variables
and also in general at
https://en.opensuse.org/SDB:Disaster_Recovery
therein in particular the sections
"Testing current ReaR upstream GitHub master code"
and
"First steps with Relax-and-Recover"

In particular regarding OUTPUT=USB on a UEFI system cf.
#2275 (comment)

So I think on a UEFI system you need to prepare your USB disk with

rear -v format -- --efi /dev/sdX

instead of plain rear format /dev/sdX as described at
http://relax-and-recover.org/documentation/getting-started
which I think is meant for traditional BIOS systems
(but I am not a UEFI expert so I could be wrong).

Thank You. I've installed Syslinux and Extlinux.
Now there is another issue.
After first command I tried the second one.
Can you help me on this?

But there is no

here.
Strange.

[jsmeix]

@celikozl
you need to use exact commands.
It is not rear format -- -- efi /dev/sdb1
but rear format -- --efi /dev/sdb
i.e. --efi (one argument) instead of -- efi (two arguments -- and efi)
and /dev/sdb (your whole USB disk will be wiped out and prepared for ReaR)
instedad of /dev/sdb1 (which is only the first partition on /dev/sdb).
Your existing /dev/sdb1 will be destroyed and recreated anew.

Because "no news is good news" I close it.
