How to Make a Bootable Flash Drive using ISObooter

[Max Headroom]

G'day rcrsn51, Unsurprisingly isobooter doesn't work w/ UEFi, Any Chance of Hacking it 2 Work as a Hybrid ie. BIOS & UEFi? :)K

Not by me, and maybe not at all. ISObooter uses tricks from Grub4Dos that are designed for BIOS systems. I don't know anything about UEFI.

G'day rcrsn51, I've Successfully ReMastered the following Puplet

http://murga-linux.com/puppy/viewtopic.php?t=106696

Burned 2 CD & Testes, But when I Add it 2 Me GumBoot ( ie. isobooter ) USB Flash Dr it doesn't work, Grub gives Error 15, File Not found, I've Tried Recreating the menu.lst File w/ Y & N answering about the Splash screen, Same Outcome

Also I'm having Trouble Getting Lobsters Photon 301 Tmxxine working...
it Boots as far as Linux initrd & then just Hangs!...

title photon301
partnew (hd0,3) 0x00 (hd0,0)/photon301.iso
map --heads=0 --sectors-per-track=0 (hd0,0)/photon301.iso (0xff)
map --hook
root (0xff)
kernel /vmlinuz pmedia=cd psavemark=1 pfix=fsck
initrd /initrd.gz

Wot am I Doing wRong? Please

Thanx 4 your Help

The "Dog" series use different names for their boot files, like "initrd1.xz". You will need to change some things in your ISObooter setup. Even then, it may not work.

Does your remaster boot when you burn it to a physical CD/DVD? If it does, I would expect ISObooter to work with "splashscreen=y".

Does the original, un-remastered ISO work with ISObooter? [Edit] I tried this and it worked.

G'day rcrsn51, I've just had 2 Upgrade Me GumBoot isobooter USB to a 32 GB USB3 Flash Dr, But Frustratingly the isobooter Script isn't working in either Linux or M$ Windows Virus Bait I'm Scratching Me Nut about whY, when in the past I've found this as So id10T Proof!?!

G'day rcrsn51, I'm Still Keen 2 get 2 the Bottom of this isoBooter issue, I Plugged it into Mint Linux, Clic'd on isobooter & it Opened the Scripts in the Default Txt Editor, So Checked the Status of if it was eXecutable & the CheckBox was Unchecked, Altho I had Previously Done it in Puppy, But when Tried Re- Checking the CheckBox it wouldn't accept it, I Dunno whY or How 2 Fix it?!?

Please Help...

:)K

[rcrsn51]

1. You never replied to my post of May 20.

2. I don't have any USB3 hardware, so I cannot comment on its ability to boot a Puppy flash drive.

3. I cannot comment on how Mint handles a script made in Puppy.

[Max Headroom]

Sorry rcrsn51, 4 Neglecting 2 Reply 2 that post...

the Answer 2 Your Question if Me ReMaster Boots from CD / DVD Media is Yes, But I Can't Remember if I got around 2 Testing the Original iso or Not, & of Course I Can't Test it Now Until I Fix the issue w/ isobooter...

Anyway it Turns Out that Me Previous 16 GB GumBoot isobooter USB Flash Dr was USB3, So I'll Rule that Out as the Problem, I Suppose I'll Try Another Flash Dr, in case it was a peculiar quirk w/ this SanDisk?!?

I Welcome Any Other Suggestions...

Thanks for isobooter, rcrsn51

I've made some modifications to make it work also with ISO's from the 'Dog' series.

So easy, successful with mintpup and Puppy Strecth, simply, two ISOs on same usb, grub4Dos, and answers to questions . Reboot, and then we go. Nice, nice,
I don't like big Linux OS, as Ubuntu or Debian. However i will try to add an old Ubuntu 11.04.
No need to format my pendrive (already FAT32), so ma previous data kept, ISO transfered between lot of files. But ISObooter finds them among the mess... Sensass.


Part TWO : now i launch Puppy Stretch.. Will it be a success ? Suspense..

[Pelo]

eh eh, success too..
My previous pupsave, still on the pendrive, loaded at boot.. We could we ask more... Some devs are really useful to thousands of puppy passengers, and of Mintpup of course
Isobooter should work as well with the other Debian dogs (XenialDog had untill now his own pendrive)

G'day rcrsn51, can yoU Please Advise the Best pmedia argument or edit 2 the menu.lst File that Helps Puppy Look 4 the Location of the Required Files ( sfs isn't it? ), Being that they're within the iso File on a USB, Not a CD or ide or sata... Sorry I'm Confused! is there a Universal Vanilla pmedia Helper Txt?

:)K

[rcrsn51]

Just to be clear, the "pmedia" argument is used by Puppy when it starts up - it has nothing to do with ISObooter.

Different Puppies handle this argument different ways, and how it works depends on your hardware. There is no "best" option.

You need to describe your particular situation.

[Max Headroom]

Thanx rcrsn51, 4 your Reply, because I've got 50 odd isos ( Puppies, Dogs, Other Linuxes & M$ Virus Bait installers ) on Me 32Gb USB Flash Dr 4 Demoing & Testing, it could be on any Variety of Hardware / Configuration, Hence the objective of a Vanilla Universal pmedia aRugment...

:)K

[rcrsn51]

The two sensible choices are "pmedia=cd" and "pmedia=usbflash". They should cover all the possibilities.

Unfortunately, some hardware doesn't like USB booting, no matter how you set it up. Here's the problem:

It's the job of the computer's BIOS to locate the first two Puppy files - vmlinuz and initrd.gz. It can usually find them on the USB drive.

It then passes control to Puppy, who tries to find its SFS file on the USB drive.

On a few computers, the USB system times out between those two phases. If Puppy cannot wake up the USB, it won't be able to find the SFS file, and booting will fail.

Traditionally, the "pmedia=cd" argument tells Puppy to look in lots of places. If it can find the SFS file on a hard drive, booting may succeed.

Thanx again rcrsn51, just confirming that it is allowed 2 have Both pmedia=cd & pmedia=usbflash for each iso? in the menu.lst on the line that says kernel or root if it's chainloaded?

And can the USB system Timing be dictated in the menu.lst?

Also Wot is the Typical Error Message 4 that issue & if I could be aware of it could I add a puppy Boot Option on the Fly?

Thanx again 4 Sharing your Wisdom!

[rcrsn51]

No. If you are booting with "splashscreen=n", you can have one or the other, but not both.

or root if it's chainloaded?

No. If you are booting with "splashscreen=y", you cannot use the pmedia option. For a Puppy, you are simulating booting from the CD, in which case "pmedia=cd" is already in place.

And can the USB system Timing be dictated in the menu.lst?

No. That is handled by Puppy.

Also Wot is the Typical Error Message 4 that issue

"SFS file not found"

& if I could be aware of it could I add a puppy Boot Option on the Fly?

It is possible to edit the GRUB menu on-the-fly, but it can be awkward.

Here is the basic idea:

1. Set up your Puppy ISO with "splashscreen=n" and the default "pmedia=cd".
2. If it boots, switch to "pmedia=usbflash" in hopes of improving the boot speed.
3. If #1 fails, switch to "splashscreen=y".
4. If #3 fails, try booting off a physical CD.

Hi Rcrsn51,

I just wanted to say "Thank You" for ISObooter. I've always installed pups + ddogs + all other ubuntu/debian-based OSes either using frugal (for pups & ddogs) and/or just using a separate, single usb or dvd to dd the ubuntu/debian OSes to. I had always wondered if I could put multiple ubuntu/debian OSes on one usb stick, just in the form of their ISOs, and somehow have that ISO launch so I could run it, and if I like, install it to somewhere else. I tried Yumi, but it is/was hit or miss for me.

Then, I I came across your ISOBooter thread here, and, well, all my questions were answered. It works fantastic. I tried it first with a large number of ubuntu/debian-based distros---all the ISOs launch just as if they were launched from their own DVD). Next up, going to try a couple handfuls of Pup ISOs.


You know, the number of things in all these different pups I like to use that have your touch & imprint on is quite a bit when I sit down and think about it. I come across your name inside many scripts when I am hunting & pecking around inside the pups. Wish I had just a little of your skills so I could do something similar for the puppy community. Thanks much again

[rcrsn51]

Thank you for those kind words. But most of the credit for ISObooter should go to Scooby's work with Grub4Dos here.

It contains the key piece of code that makes ISObooter work - how to link the fourth entry in the partition table back into the ISO, so the distro can locate all its files.

[Pelo]

Happy with isobooter but...
I installed Xenialdog alone on a 8GB usb pendrive, session is saved and boot script is modified by adding changes = Path.../changes.dat
I installed 3os (mintpup, dogStrectch, and Puppy strecth with ISObooter on another pendrive.. But i don't know where to act to get saves loaded at boot..
Any idea ?
