Ventoy is capable of that and I think other software also but I have never used Ventoy or heard of Easy2Boot. All you need to be able to do this is an installation of Grub2 and the ability to read and follow simple instructions. If you want to boot in Legacy and EFI mode, create an unformatted 1MB BIOS_boot partition and a 1-500MB EFI partition then install Grub2 in Legacy and EFI modes on the drive. You then just copy the iso files to the flash drive to a single partition or as many partitions as you want and manually create a menuentry in grub.cfg for them. I expect the last part is what most users want automated although there are example entries available for most Linux distributions online.

As to the primary question, my experience is the same as posted above, that turning off Secure Boot isn't generally that difficult. I'm not really sure why Microsoft wanted this as current windows boot without it enabled.

Another thing about Easy2Boot is that the download is an .exe file which requires Windows. Their site suggests using FAT32 filesystems on the USB which has limitations. Doing this manually with Grub2 allows Linux filesystems with larger partitions and files.

Well, that's an extremely helpful little bit of information for me. Thanks for that.

Well, now that I'm mostly using Linux, I'd like to make that choice mostly too. Even if I use Windows sometimes, and need a laptop for it, I'd like to use a Linux laptop for Linux, and Windows laptop for Windows. I'm trying to reduce windows seriously though. It's sometimes a necessary evil. But if I figure out my details, I can pretty much eliminate it mostly. See other threads for what problems I've faced, though recent shows you recent. HOWEVER, it's going to be awhile before I need to buy another laptop again though, unless for future work or school.

Why not? If you can share...

Though I was mostly using windows for awhile, Dell has been my favorite. I think as far as hardware, sometimes I "might" still like them, except for the price nowdays. That's why I've got an HP machine now. I needed something that would meet specs for school. Otherwise, I'd have bought nothing and be sitting in front of my Dell now. I still have my Dell, it's just not my main one. It's for guests and stuff now.

I'll continue reading later. I have to get ready and go now.

I won't purchase larger than 14", which many of them don't offer a 14", and for a few years I wouldn't purchase Intel because their processors were SOOOOOOOOOOOOO far behind AMD. Only Linux OEM I know of that makes a compatible system is Framework. But the problem with them is they want "pay us today for a laptop...eventually". I'm not cool with paying now for a laptop that will ship eventually. I pay now, it ships now. If you can't do that, I will find someone else. So literally not a single vendor that I can do business with currently.

I'm continuing reading now.

So I found out, that though windows only, what I needed to make for current setup, was 3 boot disks in order to cover all my current scenerios. First, is I needed a regular ventoy one, for most tasks. But I have what I now know as an IA32 machine, just one that I know of, and for that, I need version 1.0.30 of the ventoy software. However, there's one that still won't boot, software that I MUST use, oddly enough, Linux software, so I needed one easy2boot whether I liked it or not, for that sceherio. I can use my machine which is made for hardware that won't work otherwise for that. I don't know what I'm going to do when windows 12 comes out. But for now, I use windows 10 wherever I need windows, except for old windows xp servers. But I'll continue to reduce as much as I can with Linux instead. In order to do this, I need to finish my standard scripts, some code is already written, but I need to modernize it.

Oh. I generally prefer 15".

OK. That will wrap up THIS thread. Thanks!
