Hello everyone,
I am newbie with Linux and hope I find a solution to a problem I have.

I installed linux suse on win. 7 as dual boots using the boot tool "rufu" under win.7 and it worked just great.
I now want to get rid of Suse and install Redhat instead, thus I created another USB boot with rhel-server.iso, unfortunately the Linux could not boot from USB.
the question is, how to create USB boot that works for Linux?

thanks in advance

Read the "Question Guidelines" link in my posting signature. Please do basic research first before posting, because some of the very first hits in Google for "how to create a bootable usb for red hat" are:
https://access.redhat.com/documentat...king-usb-media
https://access.redhat.com/articles/142303

...guides from Red Hat to do exactly what you're after, along with many others. There are also a couple of things to be aware of:

1. Your post is confusing; you say you already have SuSE installed...but ask how to create a USB boot for Linux?? Which is something you've obviously already done, since you're USING Linux now.
2. If you are not planning on paying for RHEL, stop where you are. DO NOT load it. You will NOT get updates/patches/bugfixes, and installing software is going to be MUCH harder. Either pay for support, or load CentOS instead, which is identical but free.
3. Why do you NEED RHEL? Because it's designed for servers, and consumer-grade hardware support can be challenging. Things like wifi, graphics, bluetooth, sound, etc., aren't ON servers, so support may be spotty.

Welcome to LinuxQuestions.

Unless you have a subscription to Redhat I suggest installing CentOS instead. Since CentOS is essentially a clone of Redhat I assume that it has the same problems with the same utilities creating a bootable USB drive.

I suggest creating the flash drive from SuSE and use the dd command.

Hi TB0ne, thanks for the reply.

1. I already searchd the forum but did not find the solution I'm looking for.
2. no, not Confusing as I did say I need to get rid of Suse and install RedHat
3. I need to install RHEL because I need to use SAP HANA Database Express which can be installed only on Suse or Redhat servers. And Suse server's requirements (RAM AND HD)are very high to my machine, whereas RHEL is much less.

I created ISO BOOT USB but unfortunately SUSE does not take it into account by loading the system.

Many thanks, I'll try this.

I find this hard to believe, since there are many, MANY threads here (and on the Internet), that specifically tell you how to create a bootable USB stick for RHEL.
Sorry, it IS confusing. You said in your first post that you COULD NOT create a bootable device for your system to load Linux from....right after you tell us you had ALREADY loaded Linux on it. Both can't be true.
So again, are you going to PAY FOR RHEL??? Because if you're not, you again need to load CentOS. It's identical but free.
...and you didn't say this in the beginning, adding to your confusing post. You said you needed to create a bootable USB for RHEL, and now you're saying you have ALREADY DONE IT? Why WOULD openSUSE know about it, and 'take it into account'??? You don't boot into openSUSE...you boot from the USB stick, and install your RHEL (that you're going to PAY FOR, RIGHT?) where the openSUSE is now, overwriting it and doing exactly what you're after.

Hi CentOS
I tried to install CentOs, unfortunately it says "no enough RAM available. How much RAM does CentOs need?

The recommended min requirements for CentOS 7 is 1GB. What are the specifications of your system?

My machine has 3 G DDR2, and 3 GHz Intel Pentium!
and I downloaded CentOs from here
https://www.centos.org/download/

I installed and run CentOS 7 as a VirtualBox guest with 1024 MB RAM.

Lucky you, unfortunately I couldn't install the VirtualBox or VMware-workstation.
The CUP refuse them.

I was just implying that it should work.

Please study basic writing skills, to write what you mean by: "couldn't install VBox"

Once that succeeds, go to: osboxes.org and download a centos7 .vdi (comes in a .7z)
If you need help using the www and Microsoft Windows, ask anyone nearby.

If your problem is: centos virtualbox install tutorial
Then simply putting those 4 words into Google, will help greatly.

hi , just off hand akrageb how old are you ?

basic library skills ( read as internet research/search - not just books in a building ) is something any junior highschool ( grade 6-9) should be able to do
( i learned to use a card catalog and reference books by the 3'd or 4'th grade )

there is a now very old saying RTFM

as in think of the internet as the worlds LARGEST encyclopedia and research tool there has ever been
and as a very large Textbook for basically every subject

so how do you study for an exam ?
by asking other people ? - no
by studying the required material ? - YES
