brokenman how do you make the ISOs we download to be bootable ISOs? What steps or app do you use to do that?
Thanks.
Thanks.
?? Is the syslinux package a part of the ISO file or something I download with USM? I will look and get back to you.brokenman wrote:After the ISO is produced a program called hybridiso is run on them. It is a part of the syslinux package I believe.

I remember playing with it a while back. I created an ISO that had multiple partitions inside that were transferred to the USB when using dd. From memory (which isn't so good) you can format what isn't used on the USB as you wish.Only question is, if you do that, can you use the rest of the usb, or is it just a dedicated iso usb?
Indeed. But I'm not one for keeping secrets so little worry.Bogomips wrote:If you pursue it, will be interested to know how you get on.
Not ISO Master in LXQT? Where did you get ISO Editor? USM?Used Iso Editor to make Iso, and AFAIK Iso Editor uses El Torrito for CD.

I believe the problem is within the .img file but what, why, how, etc. and how to fix.... No idea.btw how's iso hybrid investigation getting on?
