Problem to burn a bootable nightly CD

Help
1

Hello.

I try to get a CD burned from on of the nightly anyboot images. In the end i always got something like a rescue floppy with only 3 files on it: boot.catalog, haiku-boot-floppy.image and README.html.

VirtualClone Drive mounting in Windows also shows up those files. I’ve used IMGBurn and Deepburner in Win7 and on linux with K3b and Brasero and also mounted the unzipped iso with the same result. I remember my last success install was with a “real” iso burned from the nightly hrev49237 and updated then with pkgman update afterwards.
So i did not recognize that i’ve got a problem with that.
I think i do something wrong or miss a step.

Could anybode help me?

Thank you

Jörg

iirc the anyboot is for usb sticks and you need to use a iso file to burn on a cd

The Haiku anyboot image is BeFS, which neither Windows nor Linux is able to read. I burn these to CD’s all the time and have never had an issue. When burning the image with Windows I use the IMGburn program.

Linux can read BeFS (BFS).

You did not do anything wrong. The anyboot disk is made of several parts, including:

  • A small partition in ISO9660 format, with the boot floppy image allowing to boot it from CD (this is what you see)
  • A larger partition in BFS format, where the Haiku files are stored (this you usually can’t see when burnt to a CD)
  • Some other ways to get the thing booted (boot sector and intel partition table for USB sticks)

Haiku itself should be able to access the BFS part without problems. This allows us to have all BFS features on the install disk, whereas the traditional ISO images had to use an emulation layer (called attribute_overlay) to add the ones required to boot Haiku.

This allows the anyboot to work for all cases: when burnt to a CD, and when written to an USB stick. We will probably later on update it to also support booting on EFI machines, which will require yet another part to be added (a FAT partition with the bootloader in it).

Thank you all and Adrian for the clear explanation. A newbee than i is a little confused if in Windows and Linux see a CD labeled “bootimg” and the named three files, mounted in Haiku the CD is labeled “Haiku” and you see the two folders home and system. One of my tries with one of the last nigtlies let me land in the debugger with a “panic, no boot partitions found”, so i thought it has to do with my CD.

With the hrev50766 i could boot, but now i has a hardware/driver problem, so i open another discussion.

I think the readme.html in the boot image is meant to explain how the CD is laid out. But no one reads those, right?

(we can improve it if the text is found to be confusing or incomplete).
