Expect to spend weeks if not months on it if you're new to GRUB scripts/components.When you are using Boot to VHD you must have enough capacity on the underlying disk to fully expand the VHD. unfortunately documentation on these is poor, and some modules are mutually exclusive, so have fun.īest of luck getting a robust boot menu script going. You'll also want to make sure you've insmod'ed any modules you need for your hardware as necessary (storage, USB, etc.). Which makes it difficult to make these future-proof.

Using the built-in GRUB menus won't work in many cases. In general you'll have to boot the kernels directly as shown above. boot=live union=overlay config components toram=.squashfs findiso=.

vmlinuz boot=casper file=./ed iso-scan/filename=. I just love the tool for what it is.Īssuming you loopback mount the ISO, I think these are the major args. I am in no way personally involved with Ventoy, nor do I have a stake in it. It's one of the very few tools I endorse without any hesitation or reservation. Ventoy is great!!! I'd recommend everyone to at least have a look at it. Until I discovered Ventoy, about a year or two ago, I would always be hesitant to recommend running Linux from USB, unless I knew the exact setup (or it involved someone with a decent technical skills). The situation certainly got better/easier with the years, but it can still be a gamble if an odd Linux distro will actually boot successfully from USB or not.

I honestly don't care to remember all the odd issues/failures I've encountered during those 17 years. Even if it does not support absolutely everything (last time I checked), it is by far the most hassle free and sure-fire solution.įor context, I have professionally deployed Linux on USB, ever since around 2004. Ventoy is indeed one of the best (if not THE best) tool for this.
