Unetbootin not suitable for SME10rc1 USB install

Unetbootin not suitable for SME10rc1 USB install
« on: April 26, 2021, 02:06:19 AM »
I could not install SME10rc1 from  a USB stick made with unetbootin.
In this post from CENTOS https://tinyurl.com/y5s9zkb8 i found the following:

"Not quite: unetbootin is not suitable for using with the CentOS isos which are what is known as hybrid - meaning that they can boot on both UEFI systems and on Legacy BIOS ones. The bug is that unetbootin rewrites our isos as it copies them and removes that ability from them so they only boot in legacy BIOS mode. If you boot a USB stick created like that on a UEFI machine it will fall through and boot in Legacy BIOS mode and not in UEFI mode. This can corrupt other UEFI operating systems that are already installed.

If you are wanting to write a CentOS supplied iso to a USB stick then all you need to do is copy it to the stick using dd. The same is true of any other hybrid boot iso image."

Somewhere else I found a recommendation for Win32Diskmanager which I used to make a USB installer stick. That worked. There was also recommendation for dd and Rufus both of which have Windows versions.

Cheers

Ah - thank you for that. Your link was very helpful.

I had been using unetbootin for some time to create bootable USB install kits and assumed it would still be good to go. Ah, well.....there is a lesson in everything.

Still, Win32diskmanager worked. I was going to try the "dd" command next if necessary - there is a "WinDD" utility which is the equivalent of the Linux "dd".

No worries, dd is the goto if you use a linux destop, me? win10 :-) I use Fedora Media writer...although I found one of the later versions was a a bit buggy and problamatic went back to a later Ver 4.1.4 and have not had a problem

Rufus works well for me, but I have to choose the DD mode when creating.
