Hi, can anyonte tell me a usb boot program you used and worked? tried several and none made a decent usb boot, i wanted to test mageia but seems to be the only distro i cannot create a boot usb. tried rufus, lili, etc
Is there a simple usb boot program for windows that works?
Thanks

I had a similar problem. I was only to boot after using the dd command to copy all.img to the USB which was then used to install Mageia 3 over the internet.

There are some propositions and more information in
Wiki for that purpose.

Try this command:
- Code: Select all
$ su -c "cp Mageia-3-LiveCD-KDE4-en-i586-CD.iso /dev/sdb && sync"
Use
dmesg to be certain you select the correct thumbdrive - here
/dev/sdb.
All data on this device will be overwritten so disconnect any other external drives to be safe.

Are you sure that this works? What about boot sector of USB thumbdrive?

Have you tried it?
I did and it booted just like one written with the dd command.
I'm not sure if there's advantage of one over the other.

Did you really fully erase thumbdrive before test? Including boot sector?
I might be wrong but AFAIK cp doesn't write to boot sector.

You're writing directly to the raw device ... no partitioning, no boot sector, the whole device will get overwritten. Should work.

Yes, it works. It's the way Debian does it. Notice that you are writing to the device /dev/sdb NOT a partition /dev/sdb1.
